chrysler49 Posted September 12, 2015 Share Posted September 12, 2015 Recently my Windsor has basically stopped charging while driving. Regulator and generator brushes were replaced with new last year, and generator tested fine. Suddenly, the car will just barely start charging when increasing the RPMs, but as the meter just starts to move clockwise to show charging, I hear a faint click under the hood and it won't charge. Ran a jumper from the negative battery terminal to the ARM post on the generator, and get slight movements of the pulley, but nothing constant. With the car running, I can get 6.15 volts at the battery terminal of the voltage regulator, but nothing at the field and armature posts. This sounds like my generator dying out? I've polarized the regulator. Battery does have a bit of overflow puddled on top, so I'm wondering if the generator started overcharging and then died out.

Joe Cocuzza Posted September 13, 2015 Share Posted September 13, 2015 Sounds like the regulator is bad. You can try tapping lightly on the regulator while the car is running to see if that will cause it to charge.Sometimes the points stick and/or get oxidized from lack of use. What is the voltage at the battery while running the car (rev it a little)?Also, if the battery has overflow the regulator could have "boiled" the battery by overcharging it. You need to check the battery, too. Link to comment Share on other sites More sharing options...

chrysler49 Posted September 13, 2015 Author Share Posted September 13, 2015 I did just have the generator tested. Voltage barely registered, so it looks as though it's the generator. Can a bad generator be fully rebuilt, or can you basically just replaces brushes and the bearing? Link to comment Share on other sites More sharing options...
JohnGB Posted October 3, 2015 Share Posted October 3, 2015 Just a longshot, but; check the springs that hold down the brushes; I have seen where they can get weak, lose tension, rust thru and snap. Link to comment Share on other sites More sharing options...
skyler Posted October 5, 2015 Share Posted October 5, 2015 yes, they can be fully rebuilt. there are alternators now that are built to look just like your old generator, fairly expensive but a good choice if you want it and will pay the price. the original gen. and regulator work very well as set up originally. dennis Link to comment Share on other sites More sharing options...
plymouthcranbrook Posted October 5, 2015 Share Posted October 5, 2015 The generator for my 52 Plymouth was rebuilt several years ago and works very well. Bright lights at night, good state of charge. Link to comment Share on other sites More sharing options...
c49er Posted October 5, 2015 Share Posted October 5, 2015 Nothing bad about a properly working generator. All my cars have them and they are reliable.Modern replacement regulators belong in the trash. Link to comment Share on other sites More sharing options...
