Weird battery/electrical issue
I installed my tow tune to tow boat to the beach Friday. I left programmer tuning while I went and showered after work. Came back out about 20 min later, programming was done , time to go. The truck turned over good but kinda fell off at the end before cranking like the battery was gonna die. Truck drove fine and the volts were up. We stopped one time on the way 2 min from the house to fill the boat up. Cranked fine then, cranked fine the next morning to go put boat in but would not even turn over to get boat out. Jumped it and went home about 5 min away. Cut it off and ate dinner, then it cranked fine to go get batteries checked. Test came back and said main was good, secondary to charge and test and alt had a 6v drain with everything off. So...came home...the next morning it cranked fine. Stopped by to top off boat, cut the truck off, it wouldn't crank. Jumped it, and took off cables while on the boat, and of course it cranked good. I haven't had time to look at anything but I'm hoping its just a bad battery. What y'all think?
