    On a '77 is the alternator supposed to ground at the coil/ignitor? If the ground is removed and the engine cranked, should the ground wire melt?

    Looking at a wirng diagram the white black wire field ground on the alternator is grounded with the white black ground wire on the regulator. The ignitor is also grounded at the Wb wire, but i don't see why they have to all be grounded at the same place. Should the wire melt if disconnected? no.

    The alternator is grounded thru the engine block by being bolted onto same. It sounds like you melted the fuse link. The fuse link (90982-08071), is connected in series with the +12volt side of the battery. The alternator terminal goes into the wire loom (WL) color, about a #10 size wire; thru the fuse link and connects to the + side of battery. Something is amiss in the wiring area...
