70 C20 w/HEI Starter Stays Engaged, Ignition Switch Smoked

[dmjlambert]

firedemon mentioned fusible link earlier, but I didn't see any further discussion of that in your thread. Do you have 6 to 9 inches of 16 gauge fusible link wire from the battery positive terminal to the passenger fender terminal where the 12 gauge main wire runs to the rest of the truck? It is important. You want that fusible link to burn up instead of any of your truck wiring burning up, in case some short happens in the future.

Does this look right?

That yellow wire does not look about 16 gauge and may not be fusible link. Fusible link is specially insulated flame proof wire. The fusible link is available in a short length at O'Reilly and other parts stores. I have only seen grey fusible links, so I am suspicious of that yellow wire. It is important to be 16 gauge so it is smaller and will burn up before burning some of the 12 gauge wires elsewhere in the truck. It is supposed to be 2 wire sizes smaller gauge than the wire you are protecting, and electric wire just comes in even sizes, like 12, 14, 16, 18, etc.

Your battery lifter strap is in the way, if you have one of the those emergency repair terminals that clamps onto your main starter wire with 2 bolts and a plate, I really recommend getting a new starter cable too, and I recommend not getting one that is in stock at auto parts stores because they have the wrong one. I recommend ACDelco ACD# 4BC53X GM# 88860050 cable. http://67-72chevytrucks.com/vboard/s...d.php?t=734496

Received the battery cable you recommended. Will drop it in today. Thanks for the recommendation!
