Alternators - Transistorized Regulator: Testing: Alternator
DO NOT ground field circuit between alternator and regulator nor operate alternator on open circuit with field winding energized. DO NOT ground output terminal and ALWAYS disconnect battery negative terminal before removing the wire from alternator output terminal.
Do not attempt to polarize alternator. Polarization is not required and any attempt to polarize the alternator will damage voltage regulator and wiring.
