Electrical frustration..., This is starting to piss me off. Options

[BMartin914]

So I have a recurring electrical problem in which my front marker lights, rear marker lights and rear tail light do not work.

I have traced down the wiring, see no problems. Cut open the harness and inspected as much as I can see (which is most of it) and still see NO problems (melting, arcing, etc.). Tonight I cleaned ALL the grounds (under relay tray, trans strap, fuse box, etc.). I then pulled all of the affected bulbs and planned to put them back in 1 by 1 until the fuse blew. Didn't get that far. As soon as I pulled the switch out the fuse blew.

This leads me to believe that wires are arcing somewhere, but as indicated, I see no visible melting or arcing. Does anyone have any ideas? I am at the point where I am willing to re-wire the circuit to fix the problem.

Anyone have any ideas before I re-wire this b**ch?

Thanks.

Check the front turn signal/marker light bucket. I would bet that you have crossed the ground with the turn signal connetions. The tab for the ground is connected to the housing, and if you mix it up with the power feed, you will blow the fuse. Same goes for the rear, but it's probably the front.

Drop the fuse panel, and look for the 2 wires on the 5th fuse from the left. IIRC, the wire colors are grey with a black tracer. Disconnect both and see if the fuse blows. then hook up one and see if it blows. If it doesn't, look to see which light is on, front or rear. Now unhook it and hook up the other one. NOw see if it blows the fuse. If it does, look at the one that was not lit up a minute ago. It has the short. Check with a ohm meter to see if that wire has 0 ohms to ground. Then disconnect the wires at the light and check again.

You should be able to track it down that way.

Or you could just disconnect the front light wiring and see if it blows the fuse... (IMG:style_emoticons/default/laugh.gif)
