Re: Dash Light problems
Quote:
Power goes to the no. 3 pin on the seven gauge panel and to pin seven on the 3 gauge panel. It is a pink wire from the fuse panel and it powers the fuel gauge and the temperature gauge. The lights are powered separately. to say you have a short between the black and gray wire pins means nothing unless you state the resistance that you measured because you will get a reading between the two points through the light filaments. If you are reading less than 1 ohm then you have a short but if you measure around 10 ohms then you are just reading the dash lights resistance. They are wired in parallel so you should read slightly less than the resistance of one light. Take a reading on the PNL lts fuse with the cluster plug unplugged and if you get close to zero ohms on either side of the fuse holder then you have a short in the wire from the headlight switch rheostat ( green), or the wire to the cluster plug, (gray). Don't forget that you have 2 gray wires together on the cluster plug, pin 8 or pin 12 depending on the style of cluster you have. One of these gray wires is the power wire from the fuse panel and the other wire goes to feed the heater panel light, and glove box light if so equipped. This wire is a common source for a short to ground. Before you run a jumper to the cluster plug, do a short to ground check on the fuse panel lights fuse, and if you don't read a short to ground with the cluster plug unplugged then you don't need the jumper . Make sense? Don't forget the heater panel light and that you will read approximately 10 ohms through this light if the bulb is good Then you can check The cluster for short to ground between pin 7 and 8 or between 6 and 12 if a 3 gauge cluster. Try these checks and post back.
