I have a 1971 4500TLB. The generator isn't putting out. If I ground out the field terminal and take a reading at the armature terminal, shouldn't the volts shoot up? Are there any other ways to trouble-shoot before I take it in to get rebuilt?

Yes there is anotgher way. If you follow the procedure that I sent you for testing the generator on the tractor it will give an accurate indication of the generators condition. You disconnect the two wires from the generator and the jumper the generator terminals together. Place the positive lead from the voltmeter on one of the terminals and the other on ground. If the voltage rises relational to the tractor RPM's then the generator is fine and the regulator is the next suspect. Grounding the field should cause it to not generate electricity.

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are ... [Read Article]
