My challenge truck has 3 optima yellow battery's, befor I bought it, it had been left stood for 2 years,
I charged the battery's and I thought they were ok, used it once, left it for 2 weeks and they had dropped to 7 volts,
Jump started it and was ok loaded it up and it started when we got there ( was slow to crank tho)
Went to use my winch in anger and it just stopped, (8274 with ep9 motor) but the 1st outing I used it and it worked fine dragged me up a very steep hill after they had been charged,
How can I tell if there dead or if it a small output altenator ? It's running a split charge and last time I checked it was working,
