Prestolite Alternator 24V 120A AVI147S3238HD

Prestolite alternator, 24V 120A, new unit, part number AVI147S3238HD. It is listed as an OE product with an internal regulator, Twin Leg mount, and 8 groove pulley, which makes the mounting and drive details important to confirm before purchase.

The alternator is rated at 120 amps and 24 volts, with a pulley outside diameter of 55mm. Mounting dimensions shown are 81mm inside mounting legs, 162mm mount centre to centre, and an M10x1.5/10.5 pivot hole diameter, so matching these points to the existing unit is the safest way to check interchange.

This unit is marked for Prestolite applications and is supplied as a new alternator, not remanufactured. It weighs 8.3kg and carries a one year warranty, giving you a clear reference for replacement planning and shipping expectations.

Rotation is bi-directional, which can help where the application matches the listed mounting and pulley details. The pin code is IR98, and the product group is rotating electrical under alternators.

Application and Buying Notes

The key checks on this alternator are the 24V electrical system, 120A output, Twin Leg mount, and 8 groove pulley. If any of those do not match the existing unit, the part may not be suitable even if it looks similar in other respects.

Mounting dimensions matter here. The listed inside mounting legs are 81mm, the mount centre to centre is 162mm, and the pivot hole is M10x1.5/10.5. These measurements are useful when comparing to the removed alternator or the vehicle bracket before committing to the purchase.

The internal regulator is another important point. Some charging system layouts rely on the alternator’s built-in regulation, so it is worth checking the original unit and wiring arrangement rather than assuming all 24V alternators are interchangeable.

The part is supplied as a new Prestolite alternator and carries part number AVI147S3238HD. If you are replacing a unit on a Higer Midiboss or Higer Roadboss application, cross-check the physical mount, pulley section, and voltage rating together, not one item on its own.

A 55mm pulley outside diameter and bi-directional rotation are useful identifiers, but they do not replace a proper comparison with the original assembly. A correct match should line up on the mount, pulley, voltage, amp rating, and connector or regulator arrangement.

At 8.3kg, this is a substantial rotating electrical component, so make sure the shipping and installation plan suits the weight and access requirements. If you are unsure, compare the existing alternator tag and dimensions before removing the old unit.

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 AVI147S3238HD 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 24V 120A. Part number AVI147S3238HD should be checked first. Listed voltage is 24. Listed output rating is 120. 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 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number AVI147S3238HD, 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 24 and output 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HIGER MIDIBOSS, HIGER MIDIBOSS 2009, HIGER MIDIBOSS 2010, HIGER MIDIBOSS 2011. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Please confirm fitment by matching part number AVI147S3238HD, 24V/120A specification, Twin Leg mount dimensions, 8 groove pulley, and the vehicle application details before ordering.
