Sonomatic Posted Thursday at 11:42 AM Share Posted Thursday at 11:42 AM So some of you may have seen my post on replacing the front pump seal on the Dynaflow in my '50 Special. After being down for two months, I got the car back together and noticed that the generator was severely overcharging. I didn't remember having that problem before. Looked in the service manual and found that the regulator can be adjusted for output. Yeah, maybe the original could, but the one installed now has no adjustment. I figured, old car, always need something, so I ordered a new voltage regulator from Kanter. In the mean time, I decided to drive around with the headlights on so as to not severely overcharge the battery that was already long in the tooth, (the previous owner told me it was from 2017 I think). I stopped by a freind's house to show off my recent repair, sat on the porch and chatted for an hour and a half, went to leave and, you guessed it, battery dead as a door nail. Home was withing walking distance, so, I went and got my battery charger and hooked it up for an hour or so, nothing doin'. Plan B: found a battery, in stock at Tractor Supply. Went and got the battery, set it on the ground next to the car, hooked up my jumper cables and she lit right off. Through the battery in the trunk, and, with a red face, drove my Buick home. Next day, I put the new battery in, and, found in the service manual the proceedure for polarizing the voltage regulator, or, is it more corredt to say, polarize the generator. Anyway, manual said, take a screwdriver and momentarily jump the generator and battery terminals on the voltage regulator. Terminals in the first picture, from top to bottom are FIELD GEN BATT. Second picture shows jumping GEN and BATT terminals with Screwdriver. Now the generator is charging as before, and, now I have a spare regulator on the way for $110. I've heard about this proceedure of polarizing the generator all of my life, but have never had a car that required it. A lot of you with experience with these regulator controlled charging systems probably figured out what my problem was right away. That's why we need this forum, to keep all of this knowledge alive. Thanks to all of you that do just that. 5 1 Link to comment Share on other sites More sharing options...
