I have been having the same problem. Everything checked out OK. I cleaned all the connections and it seemed to to be fine. I started to crank it the other night and it seemed like a weak battery. Then it just started clicking.Load tested the battery and it was good. Took the connections back apart including grounds.Seems good now.I'll be interested to hear your prognosis because I'm leaving for Colorado next Thursday. So hurry up and check it out!
