Junkyard 5.9 for my 72 Van

No idea what those are for, but based on the corrosion and the fact that they are just twisted wires smashed under the nuts, doubt they work.

Might as well put good connections on them and see if it fixes your problem.

Yes Dion, I was trying to knock it all out at once.
Maybe tomorrow I can cut some fresh wire and solder some connectors.
