This subject has been gone over in great detail several times. Quality of new regulators is a real issue. Old regulators used to be polarity sensitive as the two points were made out of different materials so they were reversed for pos or neg polarity. Then you have the issue of different generators used on the H, the early ones with the high low switch for charge control used a field coil that drew more current so if you use that generator with a regulator you have too much current flowing through the points and cause premature failure. Next, setting the third brush closer to main brush on adjustable models, to try to get more amps to hold the lights and battery ign, also causes more current flow through fields and thus points. I would have your service man run a field current draw test at battery voltage on the bench and if it is over 2.5 amps (very max 3) I would say no regulator would last. Those combination current, voltage regulators used on these model tractors always were less than desireable. Finding a genuine Delco, well, I think they have out sourced building their's also.

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash.

The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
