Does anyone know what all runs off of the fusable link that is connected with the battery cable to the big lug on the starter solenoid of the 1984 Fiero? I lost that fusible link. I know the coolant fan and dash instruments were powered off of it. The headlights and domelites aren't - they kept working. I'm going to replace it with an inline fuse that I'm going to locate near the upper left of the engine compartment. I just need an approximation of the load that the fuse has to support.

William...

I just went through this on an '84 that I'm trying to sell. Someone had messed with it 'cause heat had shriveled up the OEM wiring.

Near as I could tell, it is supposed to be "Fuseable Link B" described on page 271 of the Haynes manual. Should feed tail lights, courtesy lights, secondary headlight circut, dome lamp. I know this may not make sense; I could not eqate the Haynes circut to the '84 directly 'cause, for one thing, there is no battery junction block like on the later models. This is where all the fuseable links are on my '88.

If I had to guess...I would rate a fuse at 20 Amps for this circut.

move the link. don't put in a fuse. Fuse links are like very slow blow fuses.

this problem is common to many older GM cars. The best fix is to trace the end of the wires back thru the harness and trim them long enough to reach the battery. connect them to the fuse link and then attach the link to the end of the thin + lead comming off the battery. (The thin lead usually goes to a heavy terminal.) If you don't have a thin lead off the bat + then clamp it under the battery + bolt.

If you can't trace them back and get enough wire extend them with the next gauge larger wire. make sure the extension wire also has insulation rated at least 105C.

Ogre - the wire that burned open was the fusable link that connected a thick red wire to the heavy starter sol. terminal. The wire is about 10 gage. Should I just find some wire that's about 14 or 16 gage or should I purchase something from Autozone? I think I'll do as you suggest and rout it to the battery pos. terminal.
