Hello,

you can find some wiring diagrams here:

I think the lighting circuits I found in those are for US vans, which I think is different (might be wrong about that). I can scan pages from Haynes for you tomorrow if it'll help -

Starting with you brake lights you have a short somewhere clearly - this wiring starts at the master cylinder - I'd start there, and work your way back. I've seen the loom in the dash damaged before, resulting in shorts.

It's possible the short is in the engine bay too - there's a white circular connector in the little black box which you can undo - as far as I remember the lights get fed through here too - you might have a problem in there.

What do the connections at the rear lights look like? You might conceivably have a problem there - it daisy chains from one to the next.

As far as the feed to the side lights go, it's a case of tracing that back too, but it sounds like you just need to trace wires back and try and find a bad connection.

As always - it's a good idea to clean up all your earths while you're there.

Good luck finding your faults

I still use bug diagram to save time as colours hadn't changed on the lighting or indicator circuits on T25s. In fact I laminated mine and keep it in my Haynes manual in the van. Handy.

Hi all
Just an update on my lighting issues with sometimes one side working then not then opposite side working .
Tried all I could then got a auto electrician round , turns out the loom in the engine bay had melted itself to the exhaust underneath giving the faults above different supply as van moved along up and down etc .
So it's now remade off and clipped clear .
Keep an eye on yours .
Cheers Steve
