Major electrical problem!

Post by **Tero Huikko** » 21 Apr 2006 12:27 pm

Aaargh,

Drove my 360 in garage and when I tried to pull off nothing happens...when I turn the ignition key, all I get is left headlight wiper starts to turn...no crank, no lights, no nothing.

Tested: Main relay, battery, wiring....almost everything
Also when I turn the ignition key the instrument lights lit very dim...My brain hurts...help.

Tero mate, this is a completely new one on me. In what you've checked, have you checked the earth from the starter and the wires around that, as they can give some funny problems if there are issues with conductivity.

I'd imagine something could have melted somewhere, causing a break in the loom, and then a connection to something that shouldn't receive power on the turn of the key. Maybe check within the fuse box for any bridging of the terminals? With the lights going dim, something must be taking the current somewhere? I'm no expert, but the question is what, unless the starter is stuck?

Could be a bad contact where the connectors come through the bulkhead. Check if you get voltage drop on the battery supply to the ignition barrel. If when the key is turned the voltage drops a lot or disapears then it is probably a bad conection. You can overcome this by running a new wire from the battery to the ignition barrel.

Checked these too, also with a new starter/solenoid...no help

Bad earth, somewhere, or fuse box connection problem.

Bad thing is that you need to start at one end of car and fix every earth connection on car, usually problem is found much before rear bumper though, but it is really impossible to say what is causing that, could be rear lights or cigarette lighter....

Problem solved. The wiring inside the left headlight unit was faulty causing 12V to ground. Also one of the starter wires had a bad connection. Go and live! yep...

Now it's rockin again...
Thanks for the help anyways.

I'm glad you are all sorted.

Interesting fault!

Great job, car electrics are somtimes more than man can understand, but usually it is solvable, sometimes takes more work sometimes less, I have indeed found that starting one end of car and moving to other end, opening every connection, is method that helps solving most difficult problems, however it takes weeks if problem is near rear bumper

Maybe it's time to reverse the order if your leccy faults gather around the rear bumper
