[QUOTE="Pheasant Surprise, post: 6420788, member: 1103"] Battery Condition Check: Take the battery out and give it a solid charge overnight. Measure the voltage after you’ve charged it (should be near enough 12.9 or over 13v). Leave it 6 hours and measure the voltage again (should have lost barely 0.1v). Ideally drop/load test it (if you’ve got one) to see if it’s holding more than surface charge. Good battery should settle out around 12.8 v fully charged. What voltage is the battery then reading when you leave it all connected overnight? After all that, I’d be doing a charging system check, then look at the starter. [/QUOTE]
