Blowing #4 Fuse/ No Tail lights, Cluster, Parking Lights, License Plate light
All,
My 1973 Dart has a problem with blowing the #4 fuse. The car is basically a garage queen and has a very good wiring harness with all lighting previously in the car working. During a rare 300 mile round trip I discovered that I had no lights in the dash cluster or rear tails. Upon return I found a blown #4 fuse. Per the Serv Manual this is the fuse for these lights. Swapped in a new fuse and it immedaitely blew w/o any switching on of the lights. I have not been able so far to find the issue.
I inspected the taillights and cleaned and greased everything and no go. I unhooked the rear harness from the main connector and no go. I dropped the fuse box and inspceted it with no visual defects. I removed the working dimmer switch and found this. The switch was still working as I had tried the dimmer before disassembly. I'm going to unplug the parking lights and slap in another fuse to see if they/it is shorted and causing the fuse to blow.
From here I'm not sure where to go. For sure the dimmer and plastic body needs replacement, I suppose that the one cooked lead could be marginal and need insp and maybe replacement too, I see where this is not unusual for these to corrode and fail or have a huge current draw for some reason.
Who has had this issue and what was the cause of # 4 fuse cooking off? Where should I go from here?
Thanks,
Marion
