On your way home from work next week (but not election day), come by the house and you can see what I have in the Rubbermaid tubs. Or, what is sitting on the rebuild crate ....

Hit me up on outlook for the address.

Gilles, any auto electric place that rebuids starters, alternators etc should be able to help, especially an old school place. My friend up in Guelph ON can rebuild anything.

There are several interchangeable models that will replace that 60 amp alternator (NSN 2920-00-909-2483 off the top of my head). Quite frankly, they can often be repaired by replacing the voltage regulator, which is the whole rear plate on most of them. But before that, try and adjust the voltage. You have to remove a small allen key plug, and with a small screwdriver you turn a little potentiometer until you get a charge of around 28 volts.

The MLVW has an interchangeable alternator. You could check with prefair surplus and see if they still have any. The same alternator was also used on the 5 ton diesel, the M151A2, and the 5/4 ton in case you have access to any of those for parts.

They are also on ebay all the time. A search for that NSN shows them starting at $375 or best offer. http://www.ebay.com/itm/Prestolite-A...f81e13&vxp=mtr

My M151A2 alternator has a CAT Diesel exchange program sticker on it.

That may be the result of your alternator coming off a US military truck like the M35A3 which used a cat engine, although I cannot say for sure if it used this alternator, although quite possible. The M900 series of trucks also used these alternators.

These alternators were also used as a direct replacement and an upgrade for the M37, the M135, and the old gas 5 tons like the M62 if they needed the extra amperage. There was even an official modification to install them in the Canadian Ferret scout cars. I went one step further and installed them in any FV432s that I worked on or owned.
