Strage Electric Problem

[Simons]

Thanks! I only need time...

[Simons]

well, I didn't find the problem yet...

I changed the fuse box, disconnect the alternator, unplug the ecu, unplug the ignition switch connector, remove all the relays and fuses...and the problem still alive.

I check the voltage on pin 15 ignition switch connector, I have between 8,4 and 9,2v....I don't know who is fedding the +15 line(powered by ignition switch), but isn't on the fuse box or relay...I think is some damaged part who has always 12v



Any ideas??

Disconnect the starter motor

[Simons]

Tomorrow I will do it. Thanks

[Simons]

I still with the problem....I must study the schemes

[quattro-nick]

if there is install some products not origional of the car i woud disconnect those things like alarm-radio-phone system-gps-remote control for the door locks-..............
otherwise you need to look at the electrical diagrams to see which relay or ecu gets bat+30 and contact +15 so you can disconnect some to see if the problem is solved
it can be your dash itself-airco panel-central locking pump-airbag-the rest off the ecu's .................
i hope this will help your problem

[Simons]

Thanks mate, this is what I was doing...I still need to remove abs ecu, aircon panel, central locking pump, diff lock, servotronic...I need time to do it, I'm very busy

[Simons]

Finally I found the problem

I disconnect all what it have under the rear seat...nothing changed, so I decided to go again with the fuse box and disconnect the coloured plugs, when the black one was unplugged all the problems disappear, I checked for voltaje and I found 9v on the black/blue wire, bingo!! I thought

I removed the wire from the connector, connect it to the fuse box and fire up the engine, perfect. All works fine...lights, clima, dash,...so I decided to let it out

The schemes said that must be two black wires, I think that BK=black, but there is one black/blue...like they show on the blue plug for the flasher, light switch and cruise control... the wire position in the black plug said that the wire who I removed is for the reverse light switch, but the lights works fine

great
maybe there is a fault in the fusebox?

[Mikes2]

blue / black is switched 12v. goes all over the car via fuse 12

great

I changed for another one...and nothing changed

blue / black is switched 12v. goes all over the car via fuse 12

I removed all the fuses and relays and the problem continued

Today I drove the car and I found one thing that don't work...the servotronic

[Simons]

I drove the car today and the servotronic works fine, all goes well after removing the wire
