Generator fine, but 12v issues

[pharmafrog]

Hello all,

I am hoping this is a quick issue. 5500W Onan Genset running fine. It did stop and I received a 14 error code, "no fast enough" took it to Onan, they cannot recreate the issue. When the genny is running, it is running all of the 110v and the AC units, but it is not charging the battery and all of the 12v lights are kind of flickering. I am guessing inverter/converter issue , but just am not that knowledgeable about it.

What should I be looking for and testing? I have a multimeter and know what I am doing, just not in the 12v world. Thanks for the help, hopefully something easy.

make sure the converter is getting 110vac at the input; then check the converter fuses on the 12vdc output. If no output then the converter is the problem.

Check for a bad ground connection.
