When turning the switch on the display blinks randomly and can hear the fuel pump buzzing. Will not crank. Everything is dead except the winch and the fuel pump. Battery is new and charged. Just started shutting down couple days ago but would restart...not any more

Any suggestions? I checked and do have power to the switch via yellow wire. I'm thinking the switch is bad. This quad is on a working ranch gets rode every day so that switch gets used a lot.

Any input is appreciated. Thanks in advance...Jim

 

Circuit breakers are in the pdm located at the very front of the atv. Item #11 Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse This module controls several functions. Since you have a new battery this is the first thing I'd check out. Best to have a manual as it has a test for the pdm along with other troubleshooting guides along with the wiring schematic. Too much to list.Plus a manuals better than throwing parts at it. Here's one that can help.2007 Polaris Sportsman 500 EFI Service Manual PDF Download

 

Thanks for the reply. I have a manual somewhere so will dig it out.

Kept turning the switch on and off today and wala got a display and it started. Turned it off and back to being dead. Will test the PDM.
