Wiring Woes

[Noki 3.9]

G'Day,
The neighbour has a 82 Classic RR and the other day a wire fell off his starter motor and burnt itself onto the exhaust. Now the car wont turn off with the key, BUT!! if you turn the key off all the dash lights come on and when the brake pedal is pressed the car will turn off......weird huh?
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 ?

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.

[Quiggers]

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.......

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.:twisted:

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:o

[shorty943]

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

[mcrover]

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.

[shorty943]

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?:p

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

Unless it fell off while you were driving and it was unfused power. Then you could melt a lot of wiring and burn the vehicle down!

That's the beauty of the Series models. If something falls off, it doesn't matter.
You just lift up the loose floor plate, put it back on, and all without breaking the 85 Kph canter. These modern cars, they get all broken when a bit falls off.

[UncleHo]

G'day Shorty943 :)

Yup! gotta love the Series 2/2a with cotton braided looms;) and 2 x 30 amp 3ag fuses (preferably rusted ends) they either work or not, everything has it's own earth, so you can opposing lights working at various wattages and brightness:D Lose floorboards, how else will the water run out.

Are you saying your Series can cruise at 85 kph?..........Oh, c'mon!.......:lol2:

[shorty943]

Yep, but she needs a run up.:p
She terrified me at 95 down hill the other day.

Some SEries owners need 1/2 a Serapax 30 before they're game to go at those sorta dern modern speeds!:o

[shorty943]

Not me mate, ex sidecar racer. Just put the brain in the matchbox, and put the matchbox somewhere safe, she'll be right mate.:D

He had just been driving the car when he noticed it wouldnt turn off, so he had a look around and found the burnt wire. He fixed it up and put it back on the starter motor and to his suprise it still wouldnt turn off unless he pressed the brake pedel and he only discovered that by mistake :)

[UncleHo]

G'day Folks :)

Don't knock the Series;)

Down hill with the wind behind you in a 2a, 100kph is WARP FACTOR 1:D :D :eek: :eek: :D :D

cheers

95kph on a down hill roll!!!!!!!!!!!!!!


Obviously the car was either in neutral or sliding on it's roof. Quick question, how many vertebrae have you got left after this little episode 95kph on leaf shocks and series seats would not be comfy at all.

[BigJon]

I got our old Series III traytop to an indicated 120 kph once. I don't for a second believe I was actually going that fast, all the other cars on the freeway were still overtaking me:) . It was very exciting though, watching the gap at the top of the door open and close, feeling the vibrations of the retread tyres:eek:, closing my ears to the screaming engine:twisted: . Oh to be young again...

Ummj, about 3.
And I cheat, I've got a comfy seat. Don't know its originations, but I got lay back, high back bucket seat, comfy, mmm. And yes, I know there is a bulkhead behind the seat, and it won't actually lay back, but, have you got lay back bucket seats in your Series? :p
Don't ask, it was in there when I bought the vehicle. Nice and comfy though.
I have also seen 105 on the speedo, steep hill, very busy little long stroke engine, get that size 6 1\2 off the throttle now shorty. 80 to 95 ish is good. And all my lights still work. This week.
