What's the voltage supposed to be?

13.5-14.5 is what im reading in the polaris iq service manual
What page?
1.38
or 1.40 if you have an 800 but its the same
I see that, but it is not the answer that I need. The red wires are the ones that provide the 14.5 VDC. That is after the voltage regulator. What I need is the proper VAC reading coming from the yellow wires. If you look at page 4.27 under Regulator/rectifier connections, you will see it just says VAC from stator charge coils. I need to know what the actual output is supposed to be.
ski, polaris doesnt give a voltage..all testing is based on ohms readings...
have you pulled the ecu and regulator and looked at the backsides? if they are overvolting they will show bubbled/blackened sealer on the backsides..if you cant get numbers by saturday I can test mine and give you volts(just replaced my stator due to loosing the 5 tooth pickup...)
technically speaking if the ohm readings are within spec at temp the stator should be good though....
ski...lets go thru the basics..have you checked tps?, fuel pressure,fuel filter, egt ohms, air temp sensor ohms, whats the scores on the pistons look like? lean?, lack of oil?, overheated? on my mud buggy running a injected big block chevy, if I got the tps wet it would go totally eratic runability wise(after the tps dried out in the shop), only way I could cure it was to replace it..have seen several 800 cfi's now that had air temp sensors and egt sensors that tested perfect but caused eratic runability problems..changing them cured all issues..
TPS verified with analog yesterday, butter smooth.
Fuel pressure 58 lbs, never wavers
New fuel filter within the last 250 miles, less than 500 miles before that.
EGT not checked recently
Air temp not checked
I know that the pistons are lean scored by the lean wash and the AFR readings going thru the roof for some unknown reason on an intermittent cycle.
ski when the A/R goes thru the ceiling how full is the fuel tank?...kinzer was having problems with that last season....
on the tps ..have you checked base setting yet?
My trail tank was 1/2 or so. I also used to have an issue when at that fuel level but that was with the original filter and only when climbing at WOT. This is totally different. I have ridden it 5 full days after the update was done with no issues. Then on sunday toward the end of the day it started going lean but mainly in the mid throttle position, the AFR's were still good at WOT. I spent the 10 miles to the truck either WOT or off the throttle to make it back with decent AFR's.
ski, can you put a fuel guage on while you ride..almost sounds like either the pump is dying when hot, or maybe the pressure regulator in the pump is hanging open..could also put a volt guage to the pump and watch for voltage drop when it goes lean....
ski..it sounds like you have covered almost if not all the bases already..I wonder if it has to do with the wire harness..rub thru, broken wire internally, corrosion on th econnectors?..something you might try ..our napa sells this stuff..its made for computer repair from water damage...the stuff is amazing..i use it on everything I touch that involves electricity...might be worth getting a bottle and doing every connection on your sled..just to see what happens..its called stabil 22..and it is awesome stuff...

I know..I have been working on automotive electrical/computer/injection since they came out..been there..try the stabillant..it might surprise you..it looks like water..but it works....would not believe how many issues it has resolved for me over the years....
