Prestolite Alternator 12V 190A AVI2800P

The Prestolite Alternator AVI2800P is a new 12V unit rated at 190 amps, supplied as each and identified under part number AVI2800P. It uses an internal regulator and is listed with a pad mount, which are key details to confirm before ordering for a specific rotating electrical application.

This alternator is part of the AVI160 series and is described as suitable for Prestolite units. Physical mounting measurements include 108mm inside mounting legs and 190mm mount centre to centre, with a 12mm adjusting hole diameter and a 13mm pivot hole diameter.

The unit is listed with a bi-directional rotation, a 22mm shaft diameter, and insulated return. It also carries a one year warranty and weighs 9.12kg, so it is a substantial 12V charging component rather than a light duty replacement.

Features recorded for this alternator include above ground construction, self excitation, remote sense, E-Coat protection, high temperature grease and seals for longer bearing life, and a fan design intended to improve airflow and cooler operation under high output load conditions.

Application and Buying Notes

Before ordering, confirm the part number AVI2800P and compare the mounting layout against your existing unit. The important checks here are the 108mm inside mounting legs, 190mm mount centre to centre, 12mm adjusting hole, 13mm pivot hole, and pad mount style, as these dimensions determine whether the alternator will physically bolt up correctly.

The alternator is rated at 12V and 190A, so it is intended for a charging system designed to suit that output. Matching voltage is essential, and the current rating should be checked against the vehicle’s original specification or the unit being replaced.

The internal regulator, self excitation, remote sense, and insulated return are relevant system details, not just feature points. They need to align with the electrical setup already in the vehicle, especially where the charging arrangement or wiring differs from a basic external-regulator style system.

Bi-directional rotation is another useful detail to confirm when identifying a replacement. While it broadens application potential, it does not replace the need to verify the existing alternator design, mounting style, and part number before purchase.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number AVI2800P helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Prestolite Alternator 12V 190A. Part number AVI2800P should be checked first. Listed voltage is 12. Listed output rating is 190. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number AVI2800P, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 190 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking part number AVI2800P, the Prestolite AVI160 series, the 12V 190A rating, and the listed mounting dimensions and electrical configuration against the existing alternator before ordering.
