What is the normal operating temperature of an alternator?

The default setting for our alternator regulator is to progressively reduce charging once the alternator temperature reaches above 100° C ( 212° F ) and to stop all charging if the alternator temperature reaches 130° C ( 266° F ).

Does heat affect alternator?

Your Alternator’s Number One Enemy The major environmental factor affecting the life of your alternator is heat. Heat is the bane of most electrical equipment as it increases electrical resistance, which means parts or devices must work harder to produce the same output.

How many volts should a tractor alternator put out?

With the engine running at idle, the voltage at the battery or alternator output terminal(s) should be between 13.8 and 14.4V (using the DC test function on the multimeter). Turning on headlights (or spotlights) should not vary this reading too much. Below 13.7V your battery will charge slowly or, perhaps, not at all.
