There is a loose wire attached to the engine block near the alternator . Any ideas where the other end should be attached? Thanks!

Hey - thanks for the reference. It notes that the condenser is for noise suppression. If the black wire is not connected and to the ignition coil, would that cause my engine fuse (15A) to blow? My engine fuse keeps blowing when I turn the key on even though the engine starts, and runs fine. Thanks again.
If you're blowing the engine fuse but it starts, that is a short somewhere, ie. a positive wire grounding. Likely a black with yellow stripe somewhere between the fuse block and the engine bay.
I know....vague, but you either have a +12V wire (BY) hooked into a ground, or one of your BY wires is grounding. Start at your ignition coil, hunt around for any BY wires (there should be a few, verify on a 1976 diagram) ensure they are plugged in correctly. (It could be your BY condenser wire?). Then, start at your fuse block with a flash light and follow the harness back towards the engine bay looking for any shorts, exposed wires or places where wires may be rubbing (passing through the firewall).
The ol' gremlins. Takes some time but VERY satisfying to solve.
cheers from NY
Malleus - so what should the yellow/black wire with bullet connector be connected to?The black/yellow wire is the igniter resister ground. The resister is there to provide a little extra for starting, but isn't used after that. I'd bet that's why your fuse is blowing.
The black wire is the condenser lead. The igniter itself is grounded by the large screw next to the condenser.
I appreciate your assistance...I thought the ballast resister was in front of the igniter on top of the coil (see image)....now that I think of it, that might be exactly why your fuse is blowing....and yet your starter keeps rolling. You need a ballast resister to control the amps back through the ignition system. Without one, you're hitting that circuit with ?? amps....thus popping the fuse.
Your annotations are correct.Malleus - so what should the yellow/black wire with bullet connector be connected to?

Malleus - my condenser lead is blue as show in the image. Can you show me a pic of your coil/igniter/ballast resister connections? Thanks!Your annotations are correct.
The condenser (Black) lead is connected to the Black/Yellow lead from the ballast resister. I have verified this both on my truck and with the 1977 EWD.
