Thanks opt I will check all this, but where is the regulator/rectifier idk what these are

I know where this is now thanks and that is a heck of a spot for it lol

 

Okay I took the charger off and has 12.2 volts when I started it the volts dropped to 11.5 and the came back up to 12.2ish. I then reved it up and the volts climbed to12.8 I plowed the drive way about an hour and a half and the. Battery voltage after that was 11.4 I shut it off and it was the same and when I started the volts dropped to 9.3 then came back to 11.4. I did not check the regulator if you think I should still I will tomorrow after work. The only other think is it is only 18 degrees here so idk if that plays a role or not wit the voltage when starting

 

When you revved it up it should have been charging more than 12.2 volts,but again at 12.2 volts straight off the charger the battery wasn't at full charge either,that is if it could hold a full charge.What's it's showing is only battery voltage when revving. The battery probably needs replacing if it fails a load test,plus the regulator probably needs to be replaced also. I've had to replace both batteries and regulators at the same time when the regulators quit charging and a battery is constantly sucked down and had to be recharged. Doesn't take long for batteries to short out/sulfate under conditions like this.Plus depends on the age of the battery also.Look at the video I posted on load testing if you haven't already as it explains a lot. You can try to charge it again,but if it can't reach 12.6-12.8 volts and stay around there,the battery is toast.

 

Okay will do, thank you one other question what does the stator do or magneto do? Is it the regulator that charges the battery like an alternator in a car?

 

The stator sends ac current to the regulator/rectifier which changes it to dc voltage. This voltage is fed back to the battery to supply power for the lights,starter,fan,etc and should be around 14-14.5 volts on average while running. If it just shows battery voltage when you rev the engine then the regulator/rectifier diodes have shorted and needs to be replaced. Rare occasions a stator can fry a regulator,but don't think I've ever seen one on the old Sportsman do this.These little 4 wire modules really take a beating over the years.

 

HI opt, okay i went and ordered a rectifier the other day just because they r so inexpensive so that should be here tomorrow so tonight I got the rack off and unhooked the 4 wires I have a yellow, yellow-red, black and red. Between the two yellows I have 238.3. Between the yellow black I have 14.96 and the yellow-red and black I have 223.2. I measure using ohms and I measured on the rectifier side. A mechanical friend told me I should also start the wheeler and measure the ac voltage coming from the stator but he did not know which wires come from the stator and I am not doing that until I consult you. Thanks again for ur help!

 

Set you meter to ac amperage,place the red lead in the 10 amp jack. Have test leads on the Yellow and Yellow/red stator wires. Crank the the engine, keep at an idle,don't increase engine speed. Should show a minimum of 5 amps if the stator charging coil is ok.

 

Okay what did u think about what the other ohms at? And I will run out and check that now
