Product Q&A

Is this alternator a single one wire ?  Looking for one for a tractor.Ron dawgFeb 02, 2024
Best Answer:Hi Ronnie, I'm glad to assist you. No, it is not with a one-wire type of alternator. We do not carry that kind of alternator.

Is this based off a Delco 10SI alternator and what width belt is used on pulley?George H.Jan 04, 2024
Best Answer:Hi George, I'm glad to assist you. For us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, 2WD/4WD, and engine size). The VIN would be helpful.

Is this a one wire capable alternator ? This is to be used on an M274-A2 which is equipped with only a battery.LennyDec 23, 2023
Best Answer:Hi Landa, I'm glad to assist you. We cannot guarantee that it is compatible with that military utility vehicle (M274-A2). This alternator is a direct-fit part for certain vehicle applications and it comes with a 2-prong terminal power connector. It is with 12 volts and a 55-ampere rating. Please check the original specifications of the utility vehicle's alternator so you can match it with this alternator.
