I have installed a battery that I was concerned with. It seems to be fine. Is there a way to "test" the battery with it installed and using just the trailer's on board equipment?
Is there a way to test it using only the on board equipement?
Basically no. I'd not trust any of the "on board" stuff
YOu can however test it without removal
I use a dual-meter adjustable load tester from Harbor Freight. Not big enough for my big Golf Car batteries but for everythign else it can draw up to around 450 amps and takes only 15 seconds to do the test. (plus hookup and dial up time).
