I'm guessing that it's a Delco alt? Are the terminals marked 1 and 2 or F and S (I think). The former is an internally regulated 10si. The latter is the older, externally regulated 10DN. If it's a 10DN then you have a regulator mounted somewhere else on the tractor and the reg may be bad. The 10si is internally regulated... and the only real thing you need do is insure that the #2 terminal is securely connected to the BAT terminal so that it properly senses output voltage. Other than that, DO NOT ever reverse the polarity (hook the cable up backwards) or that will fry the regulator. One of those terminal wires touching ground could also be the source of your problems.... Likely, at this point you will need another alt if it's a 10si. If it's a 10DN you need a reg.
