KMG: I expect what you are refering to is polarization of regulator. If it is charging some that is not your problem. If you go to archives, do a search for "polarization of regulator" . I'm sure you will find instruction. Been so long since I've done this, wouldn't want to give you wrong info.

If you want my opinion the real problem is your generator needs rebuilding and you need a new regulator. From an economical stand point alternator is the way to go. Rebuilding that old generator, plus a regulator will probably spoil $200. You can probably do a change over for less money and have a much superior charging system.

Two ways of doing this, 1st 6 volt alternator, plus mounting and a system to excite alternator. 2nd 12 volt alternator plus mounting and a system to excite alternator. Same as 6 volt except you now have to change your battery, lights, coil to match 12 volt system.

If you wish to know more about 6 volt alternators, just type that in your favourite search engine. You will find several sources for 6 volt alternators, plus installation instructions. If your battery, lights and coil need replacing anyhow, it will be just as easy to go 12 volt.

I have a SA, 130 and 140, all with alternators. Super A has a 6 volt alternator. The only good reason for that is I had a 1 week old battery when the old generator packed up. I went to a rebuilder, asked how quick he could get me going. He said, "Quick in rebuilding that old generator is two weeks as I don't have the parts to rebuild it. Quick for a 6 volt alternator will be 5 minutes as all I need do is change one wire in a new GM Delco alternator, to make it 6 volt." That was 12 years ago, and the system works perfect. My 130 and 140 are 12 volt, I live in Canada and in sub zero weather, my old Super A is still the best starter, 130 is close. If you have any questions send me an e mail.
