Another possibility, if you haven't already checked it, is the battery charging system is not doing a good job while in storage.

Thanks guys. Do I check each individual battery connection and then go forward if they are solid? How do I check whether or not the batteries need replacing? I am still very new at this Bluebird adventure.

Yes, I would check each battery connection and cable end for possible corrosion and tightness. You can buy a battery tester from harbor freight or use a voltmeter and a temporary load (like a 12v light) to get an idea of the battery's health.

Did anything else change? Is the main engine cranking the same as before? any other indication of a low voltage condition? It may be you just need to bump up the low-voltage setpoint on the auto-start a little bit.

to test the batteries you would have to disconnect the batteries and load test each individually
you should have talked to me at myrtle beach I had a tester with me
agood battery store should have the proper equipment

Thanks again. I am in Edisto Beach for another week and will see if I can find a place to test the batteries.
I'll check the connections first. Nothing else seemed to be different. Just happened when I start it up after being connected to 50 amp shore power.
I'll let you know what is going on as soon as I find out.

Bob, it might be easier to buy a load tester. I'm lazy, and lifting those batteries out of the compartment is a job. Whereas, you can disconnect the cables and hook up the load tester. Chances are, the connectors might need a good cleaning, anyway.

Change your auto start selection from "low Voltage" to "No Voltage". If that stops it, then you've probably either got a bad connection in the battery circuit or a battery(ies) going bad.

Default Charging batteries

Although there are not many this may be an area where BMCs do not have an advantage as I have no idea when my batteries are down to 50% (no auto start or off). So far after 5 years these 2 big 12V Interstate Workaholics are still going but I have no idea if I have gotten them too low at times although one time I had to switch over to the engine batteries to start the genny. (Now I run the generator twice a day for at least an hour when dry camping and have had no more problems like that). We don't dry camp a lot but now and then (like Maxton) and the occasional night at Wal-Mart.

Anyway the point of this note is that I am not a detail guy and have no interest in running out often to check my batteries to see if it's time to start the generator. So, if there is a simple way to rig up something that I can look at occasionally without much effort when dry camping, I'd like to know how to do that. Otherwise I guess I'll just continue with the twice a day for an hour program and hope for the best.

Just use your voltmeter! When it get's down to 12, start the genny!

On my 'Bird I have to turn on the ignition to read the voltmeter on the dash, so I installed another digital voltmeter on the panel above the microwave that I can glance over to see as I walk by, it also makes vor easier viewing at night.
