This had been a regular problem with the regulators in the last 10 or 12 years or so. It was extremely rare like 30 years ago. The number two terminal must have a good tight connection or it can cause this problem also. In reality, the number two connectiion should have a wire running all the way back to the first heavy battery cable connection not on the battery. This will give regulator a much better sense how to regulate. Most of us just hook conversions to the large output terminal at the alternator and get by most of the time. All original wiring harness's the sense lead came from right near battery to reduce error causes by voltage drop in output wire to battery during heavy charge periods. I put three regulators in a alternator one day, and then finally replaced alternator to cure problem. Also, put about four in another one along with all different parts, including rotor, except the stator which I did not have a new one or good used one and then I replaced the whole alternator. Fact is, I even isolated the alternator from all other wiring on tractor by running it to a spare battery and just using the tractor to run the alternator. Now this alt has been on for about four years.
