Copying this for my notes.... :agree:It sounds like someone installed a fuseholder to replace a fuse link on the starter. You have two main circuits: Battery power - headlites, horn, brake lites, lighter, etc and Key-on power: everything that turns on with the key. Both circuits use fuse links down on the starter. A fuse holder will never be able to handle the load of key-on power.
You will find three large hole terminals in the wiring harness to the starter. The terminal attached to a black wire does NOT go on the starter lug with the other two. This wire is the ground for the wiper and blower motors. It should be attached to a bell housing bolt.
Allthough a fuse holder will not work you must have some kind of circuit protection.
Hope this helps,
I think you need a circuit tester, circuit diagram and/or shop manual to correctly diagnos this. It sounds like an electrical bubba's been in there. My .02.here are facts about car
not orginal fues holders plug style
fuse blew with old starter
heres my question what parts can pull 30 amps amd will not burn small wires
also most of the wiring looks like from factary
