snowstormer Posted August 18, 2004 Share Posted August 18, 2004 any electrical types out there? why would the fuses and wires for the headlights [where the wires go into the fuseblock] get incedibaly hot when the headlights are on? fuseblock is cool unless lights are on- turn them on and the fuse for headlights gets real hot, does not blow, yet. got hot enough where the plug- in connector on the back has started to melt. old wiring? so the resistance is too much? bad ground? fuse is the correct amperage and is tight in the connectors. should i wire the headlights on a seperate new circuit? im not an electrical genius, or any other kind, so any pointers? thanks for any replies.

Will Smith Posted August 19, 2004 Share Posted August 19, 2004 sounds like the headlamp switch to me. Do your headlamps flicker? Quote Link to comment Share on other sites More sharing options...
edrach Posted August 19, 2004 Share Posted August 19, 2004 Hot wiring or fuses indicate a bad connection somewhere. Make sure the fuses are tight in their holders. Make sure metal connectors are tight (plastic in the connector housing can turn brown from the heat indicting a poor connection). Quote Link to comment Share on other sites More sharing options...
ReluctantMechanic Posted August 19, 2004 Share Posted August 19, 2004 The energy released (heat) in a electrical circuit is equal to the current squared time the resistance I*I*R. Sounds like the current is normal since the fuse is holding. So, that means you must have a high resistant joint, probably a connector or fuse holder.

SubaruRichie Posted August 19, 2004 Share Posted August 19, 2004 I had the same problem in my 78 Brat when I got it about a month ago. The wires on the back of the fuse box were melted. Someone before me had put a resistor on the wire to try and fix the problem. The fuse box was even melted! I solved this by going to the junk yard and getting another headlight switch and a new fuse box from another brat. Works fine now. I'm thinking that was the problem with my brat. Maybe yours too. Good luck! Quote Link to comment Share on other sites More sharing options...
SUBARU3 Posted August 19, 2004 Share Posted August 19, 2004 This was a problem on all Gen 1/ Stage 2 cars. There was a recall back then to address this. They added in a new heavier fuse. If you look at most Gen 1's fuse block wiring, you will find the plastic to be either melted somewhat, or REALLY melted. Try pinching together the small cips that hold the fuse and reinsert it. Remember, resistance generates heat. Todd Quote Link to comment Share on other sites More sharing options...
