From the voltages you measured at the battery, 11.4 & 11.3, it is obvious the charger circuit is not working. Are you aware that the engine in the generator does not charge the battery even when running? This is unlike a riding mower or automobile.
The charger is usually in the transfer switch and sends a DC voltage to the battery at all times to maintain the battery in a fully charged state. Start your trouble shooting by identifying the charger and measuring the supply voltage to the charger which is usually 240 volts AC. Only do this if you have some electrical skills as you can easily hurt yourself!
Thanks for your reply:
The two readings just showed me that the generator was using a small amount more current while running than at rest.. And as you said. No charge voltage present. The battery will charge quickly with another charger, so it's not a problem
On this model, the charger is part of the control module (according to the book). So If the 120 volts input from the switch is not there.. the charger will not work. I am going to retrace my steps in checking that line ,since I had to add it when I installed this unit. Can't be a defective controller! It's new. My experience in trouble shooting a problem has taught me to check the last thing I worked on! :eek:
