I pulled my 2004 Polaris 330 Trail Boss out to get it warmed up and ready for the season. The battery has been on a battery tender since December and seems to be in good shape. After I reconnected it and hit the start button it cranked over and came to life. After about 1 minute of idling, it shut off. When I went to restart it, I had no power at all. Lights and all else dead.
I checked the battery with a voltage meter and it shows a full charge. Any Ideas.

 

check battery cables and fuses

 

check wiring for maybe a mouse nest or damage. could have chewed through something causing a short.

 

Thanks for the suggestions. I found some corrosion that seemed to be the problem.
