    Re: Battery disconnects

    In the case of a direct Alternator connection to the battery would be cut with the battery being cut, and that is by far the simplest installation, but if the alternator goes to the fuse block I would think cutting/grounding the distributor would be a simpler task than cutting the Alternator's power wire.
    Escaped on a technicality.

      Unfortunatly we have to deal with sanctioning bodies that have rules that the local inspectors can't change. You just have to do what they want. Argueing with them never seems to help.

        An alternator won't stop charging unless it goes to open or stops spinning. To kill the car you'd need to pull the power from the ignition systems to get the engine to stop running. To kill the electrical you'd have to remove the battery and alternator from the system.

        I'm planning on running a front and rear 200A painless solenoids to kill the alternator power to the front and the rear power busses. The batt switch will kill the power to the solenoids and disconnect the battery. Any problems ya'll see?

          You need a dual pole single throw switch if your going to run an alternator. The field wire on the alternator needs to be de-energized and cannot be on the same terminal as the battery feed. If the field wire is connected to the main power the alternator will continue to charge... keeping the car from shutting down! The switch you need will have 4 terminals on it 2 larger terminals for the main power and 2 smaller terminals for the field wire.
