Question about Watts Onan Portable Generator - 4000 , Model# 5500
I have an older 4000K Onan generator model # 4.occk-3cr/12002r. It uses the generator armature to start the engine. In other words, there is no starter on the generator. It was running great one day; then the next day it would not start. It sounds like the starter is dragging; but as I said, there is no starter on it.
While trouble shooting it, I connected two fully charged deep well batteries that are wired in series directly to the unit (so I know it's getting plenty of juice), and it will just barely turn over. It reminds me of an old car with a worn out starter.
Any ideas or suggestion will be appreciated.

Flight systems can test the onan circuit boards. google them they will come up. First class operation my board was was checked out and back to me in about a week, They also sell new boards and deduct the 20 dollar bench fee if yours is bad and you buy a replacement from them.

The problem is that you are not creating voltage. Remove front cover. Place a volt meter on the breaker. Start genset and you will see no voltage present. The problem could be with the brushes, rings, rotor, stator, voltage regulator, or control board.
