Reversing Light Fault

Postby CallMeLegend » Fri 04.09.2020, 18:06

Missy's reversing lights don't work, I have checked the following.

Fuse - OK
Power at fuse - 12v
Power at reversing light switch - 0v
Reversing light switch - OK

From this is appears there is either a break in the Green wire somewhere between the fusebox or there is a bad connection at the LH front harness connector. My question is, which one under the bonnet is the LH front harness connector? I'm going to pull this & check for 12v at the Green wire.

I'm not home right now, so using the phone.
This is difficult to explain in few words, but I recently had an electric fault on the fog lights that was down to the ground wire connection with the shell of the bulb enclosure.

Is your Elan orange?
If it is, I'll send you pictures on Facebook of what I'm trying to describe

So as you have +12v at the fuse do your indicators work? both fronts and rears? If they do then I would check the LHFHC under the dash on your LHS (the green wire feeds the reverse lights, switch makes connection etc etc.) I know you know what you are doing but i would double confirm that i don't have +12v on the green bullet connector to the switch with the ignition on, its a b*^#h to get your hands in there but that's where they typically fail.

No 12v at the bullet. Just a case of tracking down where I lose 12v between the fuse box and the switch.
