Prestolite AVI2800J Alternator 12V 190A AVI160 New

The Prestolite AVI2800J is a new 12V alternator rated at 190 amps and supplied as an each unit. It sits in the Prestolite AVI160 series and uses an internal regulator, which is an important check when matching the charging system layout on the vehicle or application.

This alternator is listed with a twin leg mount, 101mm inside mounting legs, and 216mm mount centre to centre. Other key dimensions include a 1/2 UNC adjusting hole diameter, 13mm pivot hole diameter, and a 22mm shaft diameter. Those dimensions matter when confirming the physical fit before purchase.

It is described as above ground, self exciting, and remote sense, with an insulated return. The unit is also marked as bi-directional rotation and has no pulley section applicable, so the mounting and drive arrangement need to be checked against the existing setup rather than assumed.

Application and Buying Notes

The main identifiers to verify are AVI2800J, the Prestolite branding, and the 12V 190A rating. If your existing alternator differs in part number, regulator type, mount style, or terminal arrangement, compare carefully before ordering, because this unit uses an internal regulator and an insulated return.

Physical dimensions are just as important as the electrical rating. Check the 101mm inside mounting legs, 216mm centre to centre mounting dimension, 1/2 UNC adjusting hole, 13mm pivot hole, and 22mm shaft diameter against the removed unit or the vehicle’s charging system bracketry.

The alternator is listed as bi-directional and with no pulley section applicable, so the drive arrangement needs to match the application already fitted to the vehicle. The twin leg mount is another key point, because alternators with a different mounting style will not interchange by amp rating alone.

At 8.88kg, this is a substantial rotating electrical component and should be handled carefully during installation. Confirm the mounting faces, belt alignment, cable connections, and regulator requirements before fitting, and make sure the vehicle’s existing charging circuit is compatible with a 12V alternator of this specification.

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 AVI2800J 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 AVI2800J 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 Twin Leg. 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 AVI2800J, 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: Please confirm compatibility by matching the part number AVI2800J, the 12V 190A specification, the internal regulator, and the listed mounting and dimensional details against the vehicle or removed unit before purchase.
