On my 77 I just purchased the fellow that had it put a 12Volt altenator on it, but mentioned he had problems keeping a charge, after looking at it I noticed that there is only 1 wire comming off it, My best guess I think there should be more, could somone tell me the proper way it should be wired to work correctly | ||

You're going to have to tell us if it's a one-wire alternator, a two wire alternator with an external regulator, or a two wire alternator with an internal regulator. If a two wire, you are going to have to tell us the make, most likely Delco, and model, most likely 10SI. | ||

ITs a Delco altenator not exactly sure what model it is but this it the info. I found on it 55A 4B 5 12neg 1100946 it has 1 external connector (stud with nut) and 2 spade connectors labeled 1R 2F hopefully this helps | ||

Your tractor was originally equipped with a generator. It's very common for people who are lazy to buy rebuilt Delco 10 SIs that have been internally converted to a "one-wire" or more correctly "self-excited" alternator. They do so because they think it's easier to hook up. Problem is, self-excited alternators wil not work on a tractor as they must spin to about 2,000 rpm before they will self-energize and therefore charge the battery. You can easily test this with a voltmeter. My suggestion is to get a tractor or automotive mechanic to install a correct alternator and wire it just like any tractor or automotive application. The standard 10si internal regulator model is cheap and available. One battery wire connection, another to the ignition switch thru a diode or "warning light", a third ground wire to engine block. It's also mandatory that the new alternator be rated at less amperage then your ammeter (if your tractor has one) or alternatively you can replace the ammeter with one rated higher than the alternator. If you forget this, you can burn the tractor to the ground. |
