I have a 2003 polaris ranger 500 that currently has no spark i was wondering if anyone can help me it would be greatly appreciated. Everything else works lights fuel pump switches. I ohmed out the trigger coil its 97ohms which is good the exciter coil is 21.5ohms which i thought was bad so i put a new stator and trigger coil in which did not fix the problem. the ign coil ohms out good so im thinking its the cdi box but i was wondering if there are any tests i can do or if anything else can be the problem. I also checked all the circuit breakers which are all good i only get .05v to the white and blue wire to the ign. coil and i only get .87v from the exciter coil at the red and red/black wire at the cdi, is that normal? Any help is greatly appreciated. And i also diconnected the black wire at the cdi and no difference.Also the key was left on for months on a battery tender dont know if this contributed to this but wanted to give all the info

 

Does make a difference if you have the series 10 or series 11 on parts. If you've got the right stator,sounds like you're down to a cdi. Series 10 doesn't have a glove box,Series 11 does.Calls for different cdis and stators for each model.Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse

 

thanks for the quick reply i guess its a series 11 it has a glove box. I ordered a cdi hope its right they didnt ask a series. But you think those voltage readings are ok from the stator. or is that not a valid test. Usually im really good at figuring this stuff out but this ones got me up in the air. Plus this is my first polaris veh. plus its got 3 modules under the hood that im not sure what they are and if they could have any effect on spark i know one is the voltage regulator but not sure of the others.

 

Resistance tests usually are more accurate. The 97 ohms you showed on the trigger(pick up) coil is spot on. Three modules are the regulator,hub safety limiter,plus a LR-58 cut off that I can't remember it's exact purpose. You can disconnect any black lead to the limiters for spark testing purposes.Leaving power on for months with a battery tender could affect any of these modules I'd suppose.Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse

 

ok thanks ill see what happens when i get it. Ill let you know
