Does an accurate wiring diagram exist?
Discussion
Hi All,
I've recently picked up my '99 Chim but have found out last night that the headlights don't work, side lights are fine, main beam works, just no dipped lights, can hear a relay clicking in the dash when turning the switch between positions so think the switch is OK, haven't yet got down into the depths of the fusebox to look at that, but as each side is fused separately it would be odd for both to have gone.
I'm thinking it's more likely the mainbeam/dip relay or something.
I bought the RV8 resource stuff thinking a wiring diagram would be on there but unfortunately the one it comes with isn't much help, does anyone know if there's a proper one anywhere?
Thanks
Ed.

Well I finally got around to having a play today and working out what was happening.
I seem to have the fuse layout posted above, thanks for that it was useful!
From this I decided to make a jumper wire to link the relay out and test the circuit, the lights worked! Brilliant, so now I'd worked out that the issue must be to do with the switch, so started pulling the bits out of the dash.
First of all, which idiot thought ribbon cables were good in a car? they're a pain! Luckily I've got some connectors that will fit so will shortly be making up some proper wiring harnesses for the switches and getting rid of the ribbons.
Decided to take out the control unit and open it up to work out what the circuits were, but when opening it up could smell that "I've got a bit hot and died" smell. This turned out to be a track on the PCB that had burnt out! So with a little link wire soldered in to fix the PCB I now have lights again!
If anyone else has an issue with this unit be careful with the link wires, this is a multilayer board so hold it up to the light to see where the tracks go.
I think the failure was possibly caused by water ingress into the unit once, there was some corrosion on the board which had linked out a couple of pins, all of this is cleaned off now.
