I have fixed a few just by adding in some suitable jumper wiring.

Unless data bus switching or whatever. Indeed, but the wiring diagram shows that the feed from the switch goes to the light via connections to the relay board. These connections are shown jumpered. I suspect that it might be to accommodate some peculiarity of regulation in a non-UK market. Chris -- Remove prejudice to reply.

To eliminate the switch, use a suitable piece of wire to join together the Grey/Yellow and Grey wires if a pre-'95 car, or Violet/Yellow and Violet if post-'95. If the light then works, the fault is still the switch. Chris -- Remove prejudice to reply.

I'm sure you could. But since the fault is likely a soldered joint failing, it would be nice to just re-flow the lot. And it's near impossible to separate the two boards to allow this. -- *Marathon runners with bad shoes suffer the agony of de feet* Dave Plowman dave(a)davenoise.co.uk London SW To e-mail, change noise into sound. |
