2 x OLD...BILL Functionally, I understand a volt meter best-shows the condition of the Batt and electrical system, as opposed to an amp meter. Wiring different but not complicated .... A Volt meter has two threaded stud terminals. One goes to ground and one to the electrical system (preferably to the system side of the starter solenoid for best reading of Batt condition. If meter dial indicator reads reverse, reverse the connections.
