<strong>Yahoo Message Number: 7879</strong>I'm having problems with my engine battery going low. With the house batteries charged up, is there not supposed to be an echo charger that charges the engine battery even when the house batteries are full? <br/>When plugged in to shore power or running the generator, is the engine battery being charged???<br/><br/>or<br/><br/>Do I have to hook up a seperate 10/20 amp...
