I have a 07 P2, that I purchased in the spring of 08. I have a pro-pak III 3-bank charger, that was replaced about 3 months into my ownership. My present (replacement) charger will not charge bank #1. Should I contact service for a new one, or deal with the Mfg to obtain a replacement? As I stated, this is the second charger that went bad. Is there a better charger I should be looking at? My first charger had similar issues, and was replaced. Thanks Rich B
