I am the new owner, and am going through repairing the hack jobs by the PO :mad:. Newest one is the charging system. It is a Hitachi alternator with three wires that connect. I am not getting any charging voltage.

One is the BAT connection which traces fine to the starter and the battery connection.

The other is a two prong connector that looks to plug into the internal regulator. It looks like a capital "T". One wire has been cut and removed, that one would be the top of the "T". I believe that one goes to the idiot light. I do not know if this model needs a functioning idiot light to make the charging system operate. I do have a manual, and that circuit shows a diode, light and resistor. It does not give the size of the resistor.

Can anyone help me with this issue, and how to rewire it properly? I do know that it is possible that a replacement alternator may be needed.

Thanks!

Here is an update... I have the alternator off the tractor. The electrical connections are Bat, S, L, E. The S is not used, and there is no tab on the diode set for S. So only Bat, L and E are used.

I'm taking it to Auto Zone for testing.

Had to replace the alt. Found a supplier that had a Mitsubishi that was an exact fit. Charging at 14.2 now.

Gray's Auto Electric & Starter had it. They can also rebuild any alt or starter. They are located in Wylie, TX.
