Hello folks, new guy here. I searched the web for an answer to mu question, and came up with little valuable info. I hope I put this in the right category, as this question is generic, but the generator in question did come from a travel trailer.
I recently acquired an Onan CMM 7000 generator. It has low hours, and runs great! I converted it to be back up power to my house bu building a Cart for to and adding a rack for the battery and fuel tank. My question is in regard to charging the battery that starts it. I have read there are different versions that have this circuit, and some do not. When I start the generator and monitor battery voltage, the battery voltage drops when the starter is engaged, I know this is normal, but the voltage seems to rise very slowly after running for a few minutes. I have not run it long enough to see if the battery fully recovers.
The model number is 7HGJAE-2132A. Can anyone tell me if this unit is supposed to charge the battery? Thank you!
