Very odd charging problem
I bought a new 2016 Precept 35US a month ago, and as far as all electrical systems go - everything has been fine.
I took a three hundred mile trip last week, driving through heavy rain at times, and things still seemed fine. Came home and plugged it in, which I always keep it plugged in.
Just went out and found the chassis battery to be dead - 2.86 volts. Coach batteries are fine.
I tried using the boost feature, and I could hear the thunk of the solenoid kicking, but no assist, no boost to start the engine.
Started trouble shooting and right now it appears that when the coach is connected to shore power, and properly charging the coach batteries, it pulls (drains) the chassis battery.
If I put a charger on the chassis batt with no shore power it charges the chassis battery. But when I plug in it starts to drain the chassis battery, even with an external charger connected. That's some drain!
First question is obviously whether anyone has heard of this problem. Second question is shouldn't the on-board charging system from shore power also keep the chassis battery hot? Thanks!
