[67L30WGN]

I checked the fuse on the opposite side (thanks for the tip) and found it was an AGA 10 amp, so that's what I purchased and placed in the empty side. Perhaps the po was popping the 4 amp fuses? Tomorrow, I'll see if my ammeter acts any different.

Without the fuse, the truck seemed to run just fine. I'm straightening out the wiring because at idle the ammeter shows discharge and the headlights dim. It may prove to be the voltage regulator and/or alternator, but I wanted to rule out the black wire since it ties in at the same junction as where the voltage regulator takes its reading (I think).

If anyone know, I'd still like to know what size the fusibible link is suppose to be off the bat (+).
