As part of the continuing saga to get my TR3 on the road after sitting for 10 years I've been fighting a short that kills my wipers, brake lights, and fuel guage for about a month now. It seemed easy enough since when I stuck my hand in the rats nest behind the center console sometimes they would start working again.
So I pulled it out about 2 inches (I can't get the oil line loose and I'm afraid of busting it) and attacked it. I found no less than 5 wires in there that had large portions of insulation melted completely off.
Hmmmm.
Replaced them and ran a new ground strap to the fuel guage as mine was GONE. Nothing left but a melted stub of wire and a ring connector.
Still nothing.
Turned on the wipers and started wiggling everything under the dash.
Still nothing.
Just for grins I started wiggling around the fuse block.
I FINALLY FOUND MY SHORT!!!! /ubbthreads/images/graemlins/smile.gif
one of the white and red wires that goes to the bottom of the fuse block makes the short come and go.
So I found a little piece of insulation rubbed off, spliced in a new wire and connector and everything started working again.
Loaded the kids for a celebratory drive around town and the stupid thing cut out again. There's a bend right where it exits the wrapping on the harness that is shorting out.
I really need to buy a new harness.
But the really exciting news is that the ignition warning light works now for the first time since I bought the car in 1984.
Small victories....
Nothing that exciting or informative for you guys but I had to share it with someone since my wife looks at me like I'm from Mongolia when I start prattling on about this stuff.
But my 6 year old is VERY excited about the new red light that comes on when I turn the key. Now he wants to know why the green one doesn't work...
