Yet Another Dash Problem????????
Black 89' coupe, 2 years ago prior to storage dash lights blew. Waited till spring to look into, here it is 2002 and still co lights at night! Replace the fuse and the fuse blows immediately when you turn the lights on..... Replaced the headlight switch and a larger fuse to try and find a bad wire and the reostat on the headlight switch heated up and melted in two, shortly after the fuse blew again. I've taken the dash out several times and replaced the bulbs still to no avail. Is it a short elsewhere or a bad ground????? Any help would be greatly appreciated.......... FRED No lights at night, what a pain..........
Black 89' coupe, trickflow heads, lingenfelter full length headers, flowmaster exhaust, airpump eliminated, new rebuilt tranny from LEVEL10 w/ a 2600 stall torque conerter+ lots more goodies and more to be added...........

Re: Yet Another Dash Problem???????? (ONEBAD89)
NEVER, NEVER, NEVER (is that enough?) install a larger fuse to trouble shoot a circuit. The original fuse blows for a good reason and you should expend your energy looking for that reason, NOT putting out a car fire.
When you turn on the parking or headlights, power goes to the dimmer resistor on the headlight control and then to the 3 amp inst fuse then to 4 panel lamps in parallel, then to ground. From your symptoms you have a short circuit to ground in the instrument cluster (unless you replaced those 4 lamps with an incorrect lamp which draw much higher current ). The inst fuse has a grey wire to pin C9 on the cluster connector. Pull your cluster and trace the circuit to find the short. Now, put your head up close to the monitor screen.......right here :smash:

Thanks for the info, I will pick the car up from the transmisssion shop this saturday "LEVEL 10" down in New Jersey and I will trace the wire out for the short. I will keep you posted after my attempt to fix. Again Thank you!

Re: Yet Another Dash Problem???????? (GWH)
One more quick question, am I tracing out the wire from the cluster to the fuse box or something within the cluster itself????? And if within the cluster what exactly am I to look for?????? Something melted or burnt????? Please respond b-4 the weekend, Thanks Again FRED!!!!!!!!
