I have a 72 Chevy 402 hei. fuseable link replaced with fuses.
i went to crank my truck the starter turned my engine over but did not crank it, at the same time my main fuse blew and my alternator belt broke.
I have installed a new starter harness, ignition switch.
Checked wires for ground with no luck.
so far with starter wired up it blows fuses only when key is turned to ignition only... I am stuck
