DESCRIPTION

AJ-ELECTRIC 4966PAA 320 Amp Heavy-Duty Alternator — Externally Regulated

New heavy-duty replacement alternator for Leece-Neville 4966PAA and A0014966PAA charging systems.

This 12-volt, 320-amp alternator features heavy-duty PAD mounting, external fan cooling and brush-type construction. It is designed for applications requiring an externally regulated high-output alternator.

IMPORTANT — EXTERNAL VOLTAGE REGULATOR REQUIRED

The 4966PAA is an externally regulated alternator. A compatible external voltage regulator is required for proper operation and is not included.

This unit is not a direct electrical replacement for internally regulated 4962PA or 4962PGH alternators.

Suitable for heavy-duty commercial, industrial and specialty vehicle charging systems originally equipped with the 4966PAA configuration.
