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. |

Have you isolated the short circuit to the front or rear wiring?
Find out which wire is shorted and then you can put the other wire back on since it should be ok. Chances are there's only one short somewhere near a light socket. Remove all bulbs and check the resistance to ground. Let me know what you find. Remember to disconnect the battery when moving the fuse box or wires around it. The 914 must have been manufactured before fusable links were invented. Any shorts on direct wires to the battery while working on the fuse box and you'll be welding (until the wire pretends its a fusable link and melts). OK, one dumb question: did you have any work done on the lamps or changed any lamps before this happened? How about any work done on the car on or near the wiring? Spoke |
