Re: Russ's 2.1 SED Auto now in Mandarin

Just to clarify how the modification should be done. I have done this, but why the reversing lights are getting power without anything connected is odd.

On some cars,reversing lights will be permanently ON when the wiring/connector is disconnected from the reverse light switch.russ92xmsed wrote:Thanks very much Chris for your explanations.
I think from what is going on, there must be a short or a power feed direct to the Rev lights.
At the moment, the wires 8&9 are not connected to anything and are isolated. Yet the Rev lights still come on when the ignition is on.
What is very frustrating is that none of the wiring any where else has been touched.
No, it just means that the fuse is between the battery and the bulbs. The fault is almost certainly downstream of the fuse, as the fuse is before the switch in the circuit.russ92xmsed wrote:Thanks for that advice. I tried it and on mine it's fuse 23. The lights go out when it's removed. So therefore it must be a fault before the fuse? Which means its in the engine bay, and most likely to do with the inhibitor wiring. That narrows it down... sort of!
Thanks Chris. Had a feeling it wouldn't be that obvious.xantia_v6 wrote:No, it just means that the fuse is between the battery and the bulbs.

Neither of us have yet turned up a wiring diag for your RP, Russ. Both those above are for later cars.
Re: Misha's point about rev.lights being able to be on when rev.light switch is disconnected, this is highly unlikely.
Russ, does your owner's handbook, if you have one, confirm the fuse number for rev.lights? Probably of academic interest, anyway!
Just a thought...Was the car ever wired up for towing? If so, rev.light switching (and/or rear fog light switching) could have been included in the add-on package. Probably a red (and white) herring.
You'll just have to chase it through, from either F23 or the rev.lights themselves.
On the latter, might be worth taking a look at the tailgate wiring, just in case the rev.lights have come into contact with something permanently live - although I'm not sure what that could be, as most of the items there are 'live switched' when needed.
Might be worth taking a look at the collection of connectors behind the rear RH tail-light, from where most of the rear-end lighting takes its feeds. Should be easy to identify anything perm live there, as well as the rev.lights*.
*confirm the rev lights by pulling your F23, so they go out, then re-supplying (via a 5A fuse!) the suspected rev.light wire.
