The Bolens 850 sometimes stalls and does not want to start back up. The generator will just hum and will not have enough power to turn the engine. The Amp meter jumps between 0-5.(What should it be?) Other times it runs fine. The output on the battery was about 12 volts and at starter generator about 5 per the volt meter. Any ideas? By the way the advice about adjusting the rear end play solved my issue with transmission jerking.

That sounds like an issue with the generator. I would check for good connections, good heavy wires running to and fro it, and then (if all else tests good) call up your local auto electric shop and schedule a time for them to replace the brushes, replace the bearings, check the coils, polish it up, and give it a kiss for good luck.

Sometimes the armature gets out of round on these things just due to stress and the common case of bad bearings. The can usually fix that, too.

The other option is to replace the whole unit. I can still get them new.

Sounds like it may be a starter malfunctioning.

These do not like dead or dying batteries so make sure you get a new battery if yours is questionable. They are not meant for constantly bringing a dead battery to life, but to just maintain a charge.

All parts are still available to rebuild these
