One thing I'm trying to figure out is which battery is for what? Is thet sealed battery in the rear the starter battery? Is that how it works which pushers? When I disconnect it the starter does not engage, so then I guess by brilliant deduction that means that the two batteries in the front are house batteries and provide power to the jacks and slide. That's got to be how it is, I can't imagine any other explanation? So if I wanted to test the Alternator does it work the same way with any car, just disconnect the negative cable from the rear battery and if doesn't stall it's fine? I did that and it didn't stall.
Thanks
