Thread: Wiring Woes

Havent heard that one before, i had an escort that would turn the hazards on when you braked, would be interesting at roundabouts watching people work out which way you were going, that turned out to be an earth.

Has the wire that burnt onto the exhaust been fixed yet cause if it hasnt that might be causing an earthing problem. Thats all i can think of, im no electrics guru.

that's weird wonder what happened to the reply i did a few days back....


there's a lot of cross wiring in LRs and by what's happened an otherwise open circuit has been closed, hence the probo.......

Has anyone else had this happen. I think he said the wire was brown with a yellow stripe and there was a wire of the same color on the back of the alternator. If the same color wire is taken off the alternator the car will turn off at the key, but the alternator wont charge??????? Any thoughts ?

Tear the loom apart and find the wires that have melted all their insulation, and are touching and short circuiting. Then replace them. Or, replace the entire loom, at least in the engine bay.
It would appear the engine starting and battery charging, and the dash lights, and the brake lights, and God only knows what else has been short circuited together, when the live wire welded itself to the exhaust.
That is how electrical fires start, a shorted circuit acts like an unthrottled bar heater, melts the wire insulation, and it is this plastic which actually starts the fire.
Yeah, probably best to look really deeply, replace the entire loom. Had to fix my lights recently, I rewired using 415V 120A industrial gear. Burn out now you mongrel.


Shorty.

G'day Folks

The Brown and Yellow usually goes from Alternator to Ign warning light, then White to Ign Switch, White to Solenoid, then White w/-tracer to starter, but on late vehicles it could well be Brown & Yellow all the way to the Solenoid Switch, that is the main live feed wire,and short(welding to exhaust will give a permenent circuit) so all lights, instruments and Accessories will be powered, it's amazing it hasn't melted the fuse box

That's what I was thinking Unca Ho, how the hell is it still functional at all?
But, it is British Leyland, right?

Shorty.

yea for land rover, you can weld all the wires together and still drive.

Replace the loom.........

Trying to repair each wire with a soldering iron and shrink wrap will take ages in comparison to changing the engine loom.

Thats a good one, I saw a Disco 2 on the Monash a couple of years ago which had been burned out, I dont know what happened but it deffinatly started in the engine bay.

We have used common single rail systems on boats for years (engine and Nav instruments and so forth), why not one big wire to do all on a Landy?

Shorty.

If a wire fell on the the exhaust, one would just remove it and put it back to where it was, wouldn't we?
