I have a couple of questions about my generator:

1. What is the maximum current output of this generator? And at what voltage?

2. Is a smaller pulley available?

MIke, smaller pulleys are available and an option, but your generators exact specs without knowing more about it cant be said exactly. What sort of problem are you having that prompted the question?? Is the belt good and tight and she operating but not keeping the battery charged??? Several problems that can occur are a battery with a weak cell, the generators brush hold down spring assembly weak or stuck or corroded, the Voltage Regulator improperly set, poorly grounded generator or Voltage regulator on and on and on. I would at least have the battery load tested and give the generator and its commutator and brushes a good cleaning and service and see if that improves performance. Good Luck, Ol John T Nordhoff in Indiana

Mike, the maximum would depend on what generator you have, what field windings you have in it, what voltage you have the regulator set at, & what RPM you spin it at. Basically the faster you spin it the higher the output, but there is a point of diminishing return & a basic upper limit. ~What is the generator number on your 50? The 50 used 2 different [factory] generators, not to mention the replacements that could have been added over the years. ~The spec on the later factory generator 11000955 is; 9-11 amps @ [13.8-14.2 volts]-Hot @2400 RPM..
~There are smaller pulleys available & depending on the size of the pulley would increase the current output slightly. ~If you can furnish a generator number I will see if I have listing for it's output @ rated RPM..... ...

My generator will produce about 10 amps or so. I dont have any problem with keeping the battery charged, but if I use my lights it seems like it does good to break even. If I don't have my RPM's up pretty good it will show a slight discharge.

Mike, if your regulator has the [L] terminal that would be about normal. It supplies power to the ignition & lights without going through the ammeter & if it comes up a little short at low RPM's you will see what the battery has to add to keep up showing as a discharge on the ammeter. A slightly smaller pulley will help some. The bottom line is: as long as the battery stays up you are good to go.....
