Recently my main battery was mysteriously drained after sitting for a couple of days. Thought it was due to a faulty radio so I replaced it and charged the battery. After a 45 minute shake down cruise I had to use the aux start feature to start the coach and the lights flickered during the ride home. The battery voltage hovered right at
12v for the duration of the return trip, and the coach started immediately after being shut off after arriving. Any words of wisdom?
