Chassis battery won't stay charged
Plugged in to 50A and for the second time in 3 months my engine battery is dead as a doornail. I replaced it a couple months ago because it wouldn't hold a charge. As soon as I put it in the MH started right up.
7 weeks later even the horn won't honk. Nada.
Pretty sure I had switch in "Store" position but can't be positive.
What's goin on here and how do I fix this?
