Subject: Westy interior light/radio mod.
Date Posted: 07 Feb 07 at 20:04

Following on from another thread (see below) here is a useful upgrade for owners of later Westfalia T3's with the blade type fuse box.

Thing is, your Westy has 2 batteries, the second battery handles the heater (where fitted) and the fridge and nothing else.
To me it seems a bit daft to have this spare battery and yet run your interior lights, radio and cigarrette lighter (Or aux. power socket) from your main "car" battery, running the risk of flattening the main battery when camped up and not plugged into the mains.

The modification outlined below will remedy this oversight and allow you to run your interior lights, radio and fag lighter from the auxilliary battery, how it should have been.

Im just doing some wiring mods in me Westy, and remembered a conversation with Mr Baxter at his garage and he said the other day that he was going to rewire his Atlantic interior lites, radio etc so they work from the leisure battery. 

I have just done said mod, heres how.

No. 3 fuse in the main fuse box works the lot.
the RED multiplug on the rear of the fusebox, terminal no. 12 has 2 thin red wires coming out, these are the feeds.
I just cut them off at the plug, connected some 17AMP cable and ran a feed from the leisure batts through a 15amp fuse, then removed no. 3 fuse from the `box for good measure.
Now all the interior fluros in the rear, radio, front interior light and fag lighter socket can be used without fear of flattening the main starter battery.

I'm a renegade from the lT forum- with a Westy Florida. Given this mod, would I be right in thinking ithat this is a Westy thing and interior lights etc on my van might also run off main battery and not leisure batteries?

Take a look at the fuse box where the wiring runs to (the wiring mentioned in the above post), try pulling the fuse that runs this circuit and see if the interior lights, radio etc stop working.

Disconnect your main battery and see if the lights and fridge workl

Fridge only works when the engine is running, or it would flatten the batt in super-quick time  Has a relay to control it

Good easy try for the interior lights and radio though

I worked out with your help by removing fuse 3 that I need to do this mod.  I just need to clarify the process so bear with me :)


1.  Snip off red wires from no.12 at rear
2.  Run 17amp cable from the leisure battery (which currently I dont know where it is and what route to take)  to no.12 at rear.
3. Fit no.12 with a 15 amp fuse
4. Remove no.3 fuse for safe measure

Do you need to disconnect battery when doing this and what materials and tools are needed e.g. connectors etc?  Not sure where to buy the materials either??

As you can tell it is the first time for me doing somik like this, so bear with me please ;)

Take care,

J

Always disconnect the negative lead before messing with the juice.

You seem to have got a bit muddled there mate, the pin no.12 red wires are in the back of the RED PLUG on the back of the fusebox (NOT no.12 fuse) they are easy to spot as they are red and paired together into the plug terminal. Cut these at the plug, then connect to the 17A cable with either an inline crimp or solder the joint and insulate it, make sure you put an in-line fuse holder or similar between the leisure battery and the joint (nearest the battery is best). Leisure batt goes under the front seats usually.

IF IN DOUBT, GET SOMEONE TO DO IT who knows what they`re doing, it`s only 12V but can still cause a wiring fire !

I'm not sure why you should cut these wires when you can just pull this terminal block apart (two spade block 5inches from the fuse box) push back the male spade connectors retaining prong to pull out the spade from the block and then plug the male spade connection onto the end of your new cable with a female fitted (reconnect the block) Nothing is cut so you retain the original connector, just needs a few turns of insulating tape and done!

All I need to do now is to change the radio switched live, to a permenant one, so I can use the radio/CD without ignition.

that block connector is only for the lights though.
Not the radio or accessory sockets.

I just did mine, super simple, I also took piccies but you can't really f**k it up, it's that simple.

Basically a red wire goes up the left hand door pillar and feeds the front interior light(s) and then goes on to feed the rear fluro's.

Easiest way to find the wire is to drop the fuse box down, and look for the single red wire that runs off in the direction of the pillar, in it is a connector, just unplug it and your lights should now stop working.

leave it unplugged and connect in your new wire from the new fuse box you just fitted to run your auxilliaries from. Tape the old supply wire up so it doesn catch owt.

right sorted, apart from where the brown cable goes. I know it is an earth
as it is strapped to metal.

You dont need to cut cables, take connector blocks apart or anything :)

This is my method and feel free to correct me :)

1. Remove fuse no. 3
2. Run 17 amp wire with a 15 amp inline fuse from the leisure battery to
the fuse box and place a spade connector on the end of the cable.
3. With your radio on try placing the spade connector into the fuse
holder no.3. First try the bottom connector and if the radio comes on the
you are done

Do u think, only difference is that you are not messing with the fuse box
wiring and can put back to standard just by putting the fuse back in :)

To be honest I couldn't get the way described in thread to work, but then
I am no mastermind :) I found it only did the lights and not the stereo.
Thinking about it all I had to do was remove the supply coming from pin
12 and replace that with the new suply from leisure, doh.

any ideas where the brown earth cable secured to the metal beside the
fusebox goes m8? bit stuck.

Appreciate your help dude

id be a bit concerned about that wire plopping out to be honest...

but It would work I suppose.

And as most T3s seem to have a fuse box area that resembles a rats nest full of tapeworms... I guess one more wire aint gonna hurt

It will work, but I can't tell you how, you will have to find out which fuse does the accessories you want to change then unclip the wires from the back of the fusebox and plug in your new wire.

not rocking horse science, the early fuseboxes are dead simple.

Just a quick note - someone mentioned in the thread that the fridge only works with the engine running.  Infact, the 12v heating element only works with the engine runing - but the cooling fan cuts in and out whenever the temp around the heat exchanger gets above a certain level - either on gas, 12v or 240v. Normally only happpens in hot weather or if the bus is in direct sunlight and the interior temp gets up a bit.

Thank you....
I have done this mod and it does work without changing the original specs.

It also was simple to remove two weeks later when I discovered that for some reason my second battery wasnt fit to start the eber any more.
I take it that only the main battery gets recharged first, and on short runs the second one never gets a "shot". No really sur though and everything works ok in the original configuration, so i'll leave that as it is.

Right...i have the early type fuse box with the bullet fuses. A technician from Summer town  motors in Broughnton, S.Devon. has so say done a similar mod that runs all the interior lights, fridge, water pump and stereo from the Aux battery. This was about 2 years ago and all has seemed to be fine.
 
However, since i rebuilt the interior after the respray the water pump for the tape is switched by the batt. indicator switch on the front of the westy cooker...rather than the tap micro switch. The tap still has a live and switch live. i have tried tracing all the wires and finding out what is going on and it all seemed as it should do. unfortunately being a bit of a numpty i messed about with things that i dont know about and tried conecting the live feed from the tap to the water pump direct. nothing happened accept now the interior lights dont work and niether does the stereo. The water pumpo does but still only switched by the batt. indicator switch. I have checked all of the fuses in the fuse board with a continuity tester, also the two fuses in the little boxy thing behind the drivers seat, also droped the fuse board and checked for inline fuses and they were fine, also taken the seat off and looked for any fuses there that may have b;lown...all fine.
 
Please give some sugestions as i dont want to re-feed supplies to the stereo and interior lights when there is probably just a fuse blown somewhere.

If it`s been modded it could be a fuse hidden anywhere Confused. The pump etc runs through a fuse in the small fusebox behind the drivers seat. Check that it`s all Ok in there, it`s prone to overheating and getting a bit cooked so check the fuse holders are all OK, if it looks crap then fit a new fusebox of  the same type.

Hello
 
I'm new to this excellent forum, and found this a very useful thread.
 
I've just attemtpted to install a blaupunck radio/cd in my newly acquired 1990 Atlantic.
 
I've got the thing connected up okay. It works - but it switches off, when i switch-on the headlights! having looked behind the fuse box, there are all manner of previous lash-ups and wires hanging about. I've tidied these up as best I can, taping and insulting. But why the radio circuit is affected by the headlights I can't determine, and not sure how to.
 
I most definately think radio/interior lights etc should run from the leisure battery and would like to make this modification, thereby i hope also removing the headlight issue.
 
One question.
 
Where does the earth that runs from the radio go to? can it be that it's the earth that is somehow connected to the headlights circuit? If so, then changing the 12v supply would make no difference?
 
Thanks for any help!

Couldn't tell you where the earth runs to via the wiring loom; but if you want to wire a fresh earth connection to the radio, if you look behind the fusebox, in the top left corner you'll see a terminal ring screwed to the bottom of the A post - should be some spare terminals on there, just run a wire from your radio to this earth ring.

Hi All
 
Just about to start this mod.....any thoughts on the best route for the wire from the leisure batt (behind drivers seat) to fuse box.  There's not really a good route up the door pillar so Im thinking under the carpet and foam underlay - is this OK?  Bit concerned it will be more subject to wear and tear.

Ran mine under the carpet, sandwiched into the underlay with some protection over the top of it. No wear on it as it`s covered.

I ran the wire under the carpet and underlay following the edge of the wheel arch then up along the edge of the seat.  I wrapped the wire in insulation tape and gaffa taped it to the floor.
 
Ive driven and lived in the van every day for the last 3 months (in Spain).  I checked the wiring today and all is well - no wear at all.

Carried out this mod on a westy today, but the wiring at the rear of the fusebox was slightly different. Connected the aux battery supply to the wire from pin 12 of the red plug (only a single wire) which then connected the interior courtesy lighting, the strip lights and the radio to the aux battery, but the cig lighter socket was dead (despite working earlier). I replaced the 15a fuse into position 3 and the cig liter was then live (remember this is with the wire from pin 12 disconnected).
After a little head scratching and looking at the wiring diagram, i discovered an additional supply from pin 11 which feeds direct to the cig lighter. Once this was cut and connected to the aux batt supply, everything worked as it should.
Maybe late van's have a slightly different wiring loom??

That's strange, I came on to post something very similar, I cut the two wires that go to pin 12, connected to the aux battery, only to find the cig lighter dead, again replaced fuse 3 and it's OK again. I'll have a look at pin 11. Cheers.

Yes, pull the radio out, find the red wire that is only live with the ignition on, cut the wire, tape up the end from the ignition side of things and forget that end, then pick up a 12v live feed  from the fusebox, one that is always live no matter what the ignition is at, there will be a few spare spade terminals at one end of the f`box in a cluster, run a cable from there, through an in-line fuse holder, connect to the wire that you cut to the radio and Roberts your mothers brother Wink

It is drawing 0.3 amps so lb wont last that long. Has anyone got away of rectifying this with out putting a switch in the radio feed wire. Thanks Simon C.

Trouble is most modern car stereo systems need the permanent live to remember station frequencies. Any constant LCD display should NOT be drawing a third of an amp...this sounds way to high. A solution could be a solar panel of sufficient output to match the small battery discharge.

T3's never had an ignition feed for the radio.
So, that current draw you did have, has always been there, just on the starter battery.
 
I have a 2 position switch, one for camping and one for general driving.
One position lets my headunit get switched on and off via the ignition, I leave it here all the time.
When I go camping I flick it the other way if I want the radio on, that lets me listen without the keys in. that feed is taken from liesure battery.

Sorry to jump in on such an old post but I've been a bit behind the times in getting this mod done.

Anyway recently I did the mod to my Atlantic 1.6TD JX - connected terminals B11 (cigarette lighter) and B12 (radio and interior lights) to a fused power feed from the leisure battery.  All works fine......I thought.

However, during a recent trip abroad I had lots of problems starting the vehicle after leaving it for a couple of nights - turned over and over, clouds of smoke and eventually started (luckily).  Once it had been running and is warm it runs and starts fine.  I'm guessing (until I can do some proper tests) that there's a possible problem with the glow plug circuit.

After a minor fix to the glow plug feed connection whilst I was away (it was pretty poor), the vehicle again started OK - until yesterday!

Then I noticed that I had turned off the cut-off switch for the aux battery - as I'm apt to do when parking up for longish periods.  I presume the PO had installed this or maybe it was from new.

My question is.....is there any way the aux battery being disconnected could affect the glow plug/starting circuit (I can't see anything from the wiring diagrams I've downloaded).  It may just have been that this was switched off when I was trying to start the vehicle whilst I was away - and by switching it on to get power to the interior fixed my problem (nothing to do with the glow plug feed wiring).

The plan today is to do a controlled starting test - with the aux battery connected - to see if things have improved.  After that I'll get the multimeter out and check the glow plug circuit is operating properly.

I did mod last night (all except fitting new fuse - so left disconnected at battery for now) and found glow circuit not working afterwards :( 
My guess is I dislodged something while pulling out the fuse box (mine is not as neat as the Baxter pic). It could just coincidentally have failed because _something_ usually breaks when I look at the van.  I was too annoyed to debug so gave up and drank beer.


FYI my Altantic wiring is 'one short length of red wire from B12 to another connector block' (as per couple of other posters) which then connected up a number of wires (3 or 4 I think) so I don't think the Baxter 'wire going up door post' would have connected everything back up again. Other wires may be radio, lighter, some strange socket on dash, and vanity mirror light.

I eventually ruled out anything to do with the light/radio wiring modification having any effect on my starting.

Seems as though my glow plugs were knackered and I didn't help matters when I tried to start the vehicle whilst still connected via the mains hook-up (apparently this is not advised Unhappy).  The timing of the problem was just coincidental.

A new set of glow plugs and a fully charged battery and I was good to go.
