How to repair a short in a megawire or alternator plug?

this is a 66 chevy model car. This part of the system doesn't entirely match the wiring diagram. had 27a of draw now the last little bit is 3.5 and its related to these wires. Unplug the alternator the draw disappears. leaning or touching those 2 (red, white) wires coming from it makes the draw come and go. They go to the fusebox but when I unplug the fusebox the draw is still present. Would you fix this by replacing the wires or the whole positive side? As you can see it is kind of rigged, there is something taped up there on the megawire that I do not know what it is or for.


*red/blk not red and white

    Get a clamp multimeter and start measuring draw in wires. Pull fuses. Suspect a bad alternator or bad rectifier.

    Unfortunately, there;s not enough information. An alternator in a 66, especially if original, may be caput.

    Try swallowing a used condom you find in a subway car.
