3. If its the engine battery and the engine is running for the levellers shouldn't that give enough power?
Thanks for help
Sorry, failed to answer all your questions. 1. Hydraulic pump and most everything in the coach works from Coach Batteries. Chassis limited to starting and small items.
With shore power connected you have only maybe 50 amps DC available. Hyd pump can draw far more, therefore large voltage drop if batteries aren't up to snuff
Engine Alt can supply the power needed but slides will not operate with engine running. I didn't get a voltmeter for anything when my coach was delivered do you?
Bad coach batteries may look charged when under the trickle for hours, the true test is when heavy load is applied they will drop quickly as the "surface charge" disappears. Hope this helps.
