[QUOTE="RossKean, post: 1451195, member: 19880"] As SkooterG mentioned, battery connections are highly suspect, especially due to the apparent intermittent nature of the problem. (Although a starter going south can behave similarly.) Swapping in another battery to test makes a lot of sense but if you don't want to buy one on a "maybe", at the very least, take it out, charge it fully, let it sit for a couple of days (to check self-discharge) and get it load tested. The definitive test for a starter is measurement of the starting current. The beast way to do this is using a Clamp On DC Ammeter. (Choose carefully, most will not measure DC amps - just AC.) Edit to add: Starting current over 80 amps then starter is likely toast. [/QUOTE]
