Hey folks.... first post! ...and brand new to campers! Picked up a '99 Coleman Utah CP for a song... so of course it needs a few things (other than a storage trunk rebuild). battery is d-e-a-d...... so I bought an everstart 27DC. got it home and checked the voltage... (-)11.71v (yes negative!) when connecting red dmm probe to + post and black probe to - post). whats with the (-) number? Even if it weren't negative, is the 11.71 normal for a "brand new" battery off the shelf? it has sticker on it 9/17, so I was assuming that was the manufacture date and that it would at least be in the 12v range. anyway... so I went to charge it nice and gently with a craftsman 2 amp smart charger. when I hook up the battery the "check battery" light comes on. Tried Schummacher SE40M. attach battery leads and before plugging in ammeter is switching back and forth between over 15 amps and 0 amps.... along with an internal clicking that I assume is some sort of breaker. This all seems just wrong to me. bad battery? Just go ahead and return it? Not a problem, and just hook it up to the se40m and let it run for a while? Thanks!
