Just purchased a 2005 Rexhall American Clipper with an auxiliary battery switch that is a single pole switch that converts the coach batteries into chassis batteries for the purpose of starting the motorhome. Book says to press and hold the switch to engage the coach batteries and release the switch after the motorhome starts. The switch has an indicator light that is on most of the time. It is on when the home is parked and plugged in to a 110 outlet or when cruising down the road. My question is, should the light be on most of the time? This indicates that the coach and chassis batteries are connected most of the time. I would think that the light should only be on when I press the switch to connect the batteries. Any thoughts on this?
