Well, have you ever had a fusable link go? Yeah the car died. There is no juice to anything. Nada. Nothing.
Twisted fusable link wire back together and touched positive cable to battery and it melted in half again.
No doubt a direct short. Wondering if anyone has experienced this problem with a alt. or starter shorting internaly.

K, Steve. disconnect the batt cable to the starter solenoid away from the block or frame. then touch the battery cable to the + post. if it sparks, your cable is grounded severly Its possible that the solenoid itself fried out and internally grounded. Your starter itself wouldnt have grounded and be noticable unless you turned the key and tried to start it to get the cable to melt. Check those out and let us know. Thats the only real direct trace to ground other than the line going to the horn relay on the radiator support. Try there next if the first doesnt solve it.

If the diodes in the alternator short out you could potentially have a pretty low resistance to ground. Should be easy enough to isolate by disconnecting the alternator.

Found it. Had a zip tie back behind the bellhousing break & let the alt. wire hit the header. It was behing everything & very hard to see but glad it was an easy fix.

Re: Direct short, fuseable link meltdown, can.....

ok, i know this is an old topic but i just had the same thing happen to me. my 69 has been apart again for about 2 or 3 years. i decided to to a complete nut and bolt resto. anyway, the 14g fusable link from the pos cable melted. this really sucks when you are getting excited to start the car for the first time in years. i guess from reading this thread, it can be the alternator or the starter. the short only affected the fusable link from the pos cable to the junction block behind the battery. i have all new wiring in my camaro so the wiring should be find. i had taken apart my alternator and starter to clean them up so i am wondering if that could be the problem. maybe i put them together wrong. i am guessing i can unplug the alternator and see if it still shorts. if it doesnt, i guess that will be my problem. any other suggestions? i dont feel like buying new battery cables to try and track down the problem and have the keep blowing.

thanks
angel
