Generator/house battery issues

Have a few issues, not certain if related. First, my house batteries are not charging, either with chassis running or generator. If I tried to run anything 12v in coach all 12 v shuts off, the light on the coach switch goes out. I assume this is because the house batteries are drained (testing at 11.2v). At the same time this started, my generator is shutting down when driving. It ran for 24 hours fine, then hit the highway and it shuts down. I have no idea if these issues are related, wwhere to start looking. Any thoughts appreciated.

At 11.2 volts, your coach batteries are 'dead'...
To charge (with any of genny, shore power, or chassis engine) the use/store switch must be in USE position.

When you say 'If I tried to run anything 12v in coach all 12 v shuts off,' - is this with the genny running??
With genny running (or on shore power) - the converter would be providing 12v to the coach... A bad converter could explain the not charging as well.
To test converter - disconnect the coach batteries, and measure the output of the converter with a voltmeter (with genny/shore power) Should be around 13v...

Search the forum for threads on genny turing off while driving... Several are having that issue - suspecting overheating.

With genny running all coach power works.

So tends to suggest the converter is good.
What voltage do you read at the batteries when the genny is running?

With switch in 'USE' you should read in the neighborhood of 13v.
If not - check out the use/store switch... (connects the converter to the batteries when in 'Use'.)
If so - test the batteries - they may no longer be capable of holding a charge.
