battery not charging on generator?

I'm standing here in my 3050S Sunseeker running my generator and I see I don't have a battery charge light. When connected to shore power I do have a charging light.

Any thoughts?

Correction, not charging on shore power either, just fully charged maybe?

What battery charge light are you looking for? I'm not aware of any light that shows the battery is "charging". In the control center, holding down the "battery" light will show you the condition of the battery. However, when you are connected to shore power, or have the generator running, it will show four lights or full. It only gives an indication of actual charge when not connected to 110v power. You can always use a volt-ohm meter to check voltage at the battery itself. A "charging" battery will have 13.2 to 13.6 volts across the terminals.

I have had the same thing happen to me while hooked up to shore power for an extended period. I have just assumed that the battery was charged and the charger had shut down. after a while, the light was back on.

I would try the voltmeter approach to see if the battery is charged.

I think the generator simply supplies 110V power to the system and transfer switch and the convertor does its' thing regardless of the source of power. I think...

If you use a voltmeter with either shore power or Genny on...you should see a minimum of 13.2 volts if it is nearly full...up to around 14.5V if the batts are depleted. Measuring at the terminals is NOT measuring battery charge...it is measuring charging voltage.
To measure battery state...disconnect the negative wires and wait at least 6 hours and preferably 24...then measure at the terminals...you should see 12.6V if they are charged fully.

Found the problem

Today I found the battery was partly discharged and the converter was not carrying house loads.

Investigated, and found one of the 35 amp fuses on the converter was blown. Couldn't find a 35 amp blade fuse locally so had to go with a 30 amp.

I suspect the fuse may have blown due to a faulted chassis battery so I disconnected the battery and now the converter is working fine.

Thank you for keeping us updated on the
final outcome. Many folks just seem to
go away somewhere after they are given
info on a forum
