Loss of Power when Furnace Blower Shuts Down??? Help!!!

Or if you don’t have a voltmeter, just see if the cheap indicator lights go from full to charge after plugging in the shore power.

My status panel does not indicate charge, only voltage. When on shore power, it will read max (12V). With full batteries, it will read the same when you disconnect shore power. But, it's 30 years old.
