12V Generator for International, Triumph, MG, Austin and more 1300, 2000, 354 1954-1980

This one is 12V. It is rated at 25 amps. Voltage has to match your machine exactly. A 12V unit on a 24V system will be damaged, and a 24V unit on a 12V system will crank slowly or not at all. If you are unsure, check the battery setup: two 12V batteries wired in series usually means a 24V system.

We list 54 vehicle and equipment applications for this generator. Use the "Does it fit?" checker further up this page to pick your make, model and year, or open the full applications list.

The surest check is the number stamped on the unit you are replacing. Match it against the cross reference numbers on this page. Fitment lists are a guide, and the same machine can leave the factory with more than one setup, so the number on your old part beats a model year every time.

Probably yes. One unit is sold under many numbers by the vehicle maker, the original manufacturer and the aftermarket. The cross reference list on this page shows the numbers we know map to this generator. If yours appears there, this is the right part.

If your number is not listed, try our cross reference lookup. It searches every number we hold, not just the ones shown here.

15017 is the Lester number. Lester is the long standing industry catalogue for rotating electrical, and its numbers are how the trade identifies a unit regardless of who sold it. We use it as our part number because it is the one identifier that stays stable across every brand that has ever boxed this generator.

A generator makes direct current directly and needs an external regulator, usually a cutout relay or a voltage regulator box on the firewall. An alternator makes alternating current and rectifies it internally, and on most units the regulator is inside. Alternators charge at idle, generators generally do not.

They are not a drop in swap for one another. Converting is a real job involving the wiring and the regulator, not just the unit.

Usually yes. A DC generator has to be polarised to the system after installation so its residual magnetism points the right way. The exact method depends on the regulator, so follow the procedure for your setup. Skipping it can mean no charging at all, or a generator that motors and burns out.

New. Every generator we list is a new unit, not a rebuilt core, and it carries a one year warranty. There is no core to return and no deposit to chase.

Orders leave within three business days. Ships from USA. You can read the full terms in our shipping policy, and returns are covered in the return and refund policy.

Returns are accepted within the window set out in our return and refund policy,and a restocking fee applies unless the part is defective or we made the error. A unit that has been installed or used cannot be returned, so it is worth confirming fitment by part number before you fit it.
