I think the battery in my 97 is going out. The truck sat for the past 3 months and of course the battery was drained. Put the battery on a trickle charger, and it got to 100% within an hour, then the charger continually cycles on and off ~1second. Put it back in the truck, turned over once or twice, but wouldn't keep a charge. Back on the charger, doing the same cycling. Reading 12.05V with no load on battery. Is it shot? Anyone know what the cycling is all about?
