I have replaced the 6V voltage regulator on my 1951 Farmall cub three times this year. Nothing is new on the tractor (i.e. same wiring, electrical system & parts that have been on the tractor for years). Symptoms are that the regulator works fine for a month or so, then it stops charging. I tap the regulator and it works for something like 15 minutes and then stops charging. I also re-polarize the regulator which, again, gets it working for a short while. Finally it quits completely and I can do nothing to get the regulator to work. There is never any evidence of what has failed - no burn smell, everything clean and new looking, contact points look clean and are easy to work with my fingers.
What might be causing this failure and is there a way to detect what is happening (e.g. measure voltage at some point)?
