I am brand new to this forum but I have owned a Polaris 850 Sportsman since 2008.
This last year I have experienced a dead battery on multiple occasions but just thought it was due to weather, etc. I bought a new batter last month, worked fine for a few weeks and then last week it was dead. The quad has been stored in the garage since I got the new battery.
I figured it was time to investigate this issue. Upon many searches on this forum, I think I have isolated it to 1 circuit (5amp). But I’m now stumped and need help from everyone.
First thing I did was the "Key Off – Draw" test. This shows the following.
1. With 5amp fuse in place and voltage reg connected; draw is just over 11.6v
2. With 5amp fuse REMOVED, voltage reg connected; the voltage drops slowly from 11.6v to around .04v after 5min
3. With 5amp fuse REMOVED & voltage reg DISCONNECTED; i show .04v stable.
Can someone please help me with what to check next?
Thank you for any advise / help you can lend.
Thank,
Mike
