Instrument cluster dead: solved

[Damien Gaboury]

Thank to the numerous peoples (Todd, Steven, Elliot, Ottar, Dan Z..) that
have suggested various solutions for solving my problem. As expected, the
problem was related to the wire harness in the truck. 6 of the 7 wires were
broken and they were all together in short circuit. I have spited the
harness and added a section of wire for all the seven in order to ensure
good flexibility in the hinge. The reparation involve soldering of new wire
sections that I have grouped under a rubber tubing to protect them. The
modification looks stock.

For the benefice of the list, below are the problems encountered in relation
to the short circuit in the truck wiring harness:

1- Erratic operation of the central looking doors when opening and closing
the truck;

2- Alarm doesn't want to be armed sometime.

3- Burned fuse on the licence plate light.

4- Finally the burning of the instrument cluster fuse: everything "dead"
including speedometer, odometer, tachometer, clock, warning lights, and the
all the gauges (water temp, oil temp, voltmeter, oil pressure and fuel).

Hope that the information will help other peoples.
