just so I understand this.....the correct wiring for Clint would be
battery + to solenoid to ammeter to fusebox to alternator?....or battery + to solenoid to ammeter to alternator and also to fusebox?
I'm asking cuz I have my '59 alternator wired direct to the battery (it isnt a one-wire alternator, has a regulator on the firewall, but I am guessing the concept would be the same)
