Re: How many volts needed at a starter

Try jumping from the large cable post on the solenoid to the solenoid S terminal. This eliminates the S terminal wire. If the solenoid is not connecting the starter cable with the fields, the starter won't turn but the solenoid may click. 8 volts at the S terminal is unacceptable. This test will put a full 12 volts on the solenoid. Be sure to disconnect the coil or the distributor so it wont start.


This what you are contemplating?

If you are losing 4 volts at the S terminal then you have a large resistance on the purple wire circuit and it's probably just a matter of time until you lose all your current in the purple wire.
