Alternator Regulators - S.E.V. MOTOROLA: Description: Alternator

Do not ground output terminal. Always disconnect battery negative cable before removing wire from alternator output terminal. Do not attempt to polarize alternator as polarization is not required and any attempt to polarize will damage voltage regulator and wiring harness.

S.E.V. Motorola alternators use either an electronic or mechanical type voltage regulator. The electronic unit contains neither mechanical contacts nor relays; it requires no adjustments or maintenance. Unit is sealed, and if found defective, it should be replaced. The mechanical voltage regulator is a dual contact unit with upper and lower moving contacts. Regulator also contains three resistors and one thermistor.
