Well guys, I've finally had a chance to do some work on my electrical problem, but ran into another problem that has me scratching my head. Before I left AZ, I realized the batteries had been boiled dry, I think, because of the solar panels. Anyway, yesterday I went to Lansing, and bought 4 new batteries, from Batteries Plus. Today, I figured I'd take the coach down to the shop, power wash the battery compartment, with the idea that I would clean it out and re-paint it. Well, to my surprise, only the dash lights would light, none of the interior lights would work. so I went back, checked the chassis batteries, removed them, and cleaned them up and checked them, they both pulled 13 voltsl So took them back down, cleaned the battery tray with a vacuum cleaner, put them back in. Same result, nothing. I'm really scratching my head at this point. My Son-in-Law, suggested putting the new coach batteries in, couldn't hurt!? Well, it didn't hurt, she fired right up?! What did I miss? Could it be the ground on the 2 battery banks are on the same ground, and with the coach batteries dead the chassis batteries didn't have a ground until the new batteries were on line?? I know this sound weird, but this has had me really scratching my head. Has anyone got an idea about why I needed all 6 batteries to make it run? Why shouldn't it start with just the chassis batteries??
