yea i saw that it was a solenoide w/ a strange name on the diagram, the name thru me off thanks. i know where they were located.

 

Hi all I got around to doing some checking on my tach problem today I checked the battery it only has 12 volts when runing and 12 when its shut off it should have been chargeing around 13.8 volts corect and the white wire with the red strip which I think is the tack wire has no volts when tested so whats everyone think whats bad ?

 

The voltage at the battery should be 13.8 to 14.5 VDC when the engine is revved up. Also the tach signal should be AC not DC.

 

ya thats what I thought but it just stays at 12 volts at idel and no change when revved up got any idea what to do or whats bad? and what did you mean by ac and not dc?

 

Your bike has a magnet in the flywheel that passes the stator coils, this produces AC current (like in your house) not DC current (like in a battery). The voltage regulator converts the AC to DC and limits the voltage to about 13.8 volts.

If I were you I would check the battery charge coils on the stator. You can test this at the plug on the voltage regulator. The voltage regulator is in front on the radiator on a 2002 400 Sportsman. Pull the plugs off and make sure the red one (2 wires) has 12 volts with key on or off. With meter on ohms make sure the brown one (2 wires) has less than a few ohms to ground.

The voltage regulator will have a few other wires. If your 2004 is the same as a 2002 you will have a yellow, yellow/red, and yellow/brown.
yellow to yellow/brown - .17 ohms
yellow/red to yellow/brown - .17 ohms
yellow to ground - no connection

If the stator checks out I would suspect the voltage regulator.

 

I use to work at a polaris dealer freedom is got all your specs, like he said the stator is like the altanator on your car, if it checks out fine then it is your voltage regulator or a bkoken wire. if you did'nt want to check your stator first you can check your voltage coming to your voltge regulator 14v to 15v and it should knock it down to 13v to 14v going out to your battery. hope this helps
