rewiring charging system

I'm sorry, but I am very confused by this post. It may be a communication problem. The starter relay is the small silver box on the firewall and the starter solenoid is the unit mounted down on the starter. Everyone is saying run the alternator charging wire to the starter relay, which is on the firewall. Maybe I'm wrong but I've never seen that done before.

My point above, is that if you get "a bunch of stuff" hooked to the starter solenoid ON THE starter, "it moves." Shakes and vibrates. More and more connections there promotes the thing coming loose.

The starter relay is a junction point "the big stud" and nut connection. Cars vary over the years. Some years, the main battery cable went from the battery TO the starter relay, and then a second cable went from there to the big starter solenoid stud.

If you use the relay for the alternator you SHOULD have a large jumper from the relay to the battery.

You should also have a large fuse / fuse link or breaker in the alternator conductor.

Yet another way is to buy an aftermarket remote insulated terminal.............The marine industry uses them. Mount this somewhere and use it for a junction for a battery cable.

Lots and lots of ways to do this. Someone mentioned running direct to battery. You can do that, but as top post batteries eventually tend to corrode "up there" this might create complications.
