Super Jet Stator Charging Voltage

What should the charging voltage be at idle from a 61X stator? Today I noticed my battery ran low, after riding for the day so I went home cranked it and put a voltmeter on the battery while it idled. I got anywhere from 14.5-17.5 volts? Also, my battery only had about 12.1 volts with the engine shut off. Could a bad battery cause the stator to over charge? Perhaps problems elsewhere?
 
14.3-15.3 volts output according to the manual. If your battery is only holding 12 or so volts even after being on idle then you should try a load test on the battery. A cold battery should hold 12.7-13.5 without concern. 12.1 sounds like there may be a buildup of sulfur on the internal plates or one or more internal plates have arced together draining the battery down and killing the needed cold cranking amps. The voltage regulator sounds like it might be failing too with such high output. The charge coil will produce as much as the rpm's will generate, the voltage regulator is what maintains consistent limited voltage.
 
I understood what he meant (lighting coil). I tested my lighting coil and it checked out, so I guess my regulator is bad, perhaps battery? I stuck my battery on the charger and so far it's held 12.7 volts, I'll keep an eye on it over the next couple days to see if it drops. I'll throw a new regulator in as well.
 
Forgot to provide my conclusion here, not sure if it'll help. But in my diagnosis I skipped an important step, and immediately concluded I had an electrical box issue which wasnt the case. I ohmed out my stator lighting coil and it checked out fine, even after wiggling/bending the wires the entire length. So, naturally I thought my voltage regulator was bad. So I ordered a new one, charged my battery and went to test. I was still getting strange voltage readings every once in a while but not as bad. At this point i was like screw it, and just figured I would see if the battery died again, and if so replace the battery. On the day I went to test, I came in, made a fuel screw adjustment and went to go back out and got no start/solenoid clicking battery was fully charged and only did about 20 minutes of riding. To say the least I was frustrated, because I was not sure what was causing it, and I figured my next move was to replace the battery.

I get home and do a bit more diag. and conclude its the battery, but then I bump the ground cable and the ski starts to turn over again. AHA!! perhaps a ground issue. I trace my ground wire back to the starter and find the starter bolts backed out slightly and the ground cable loose. Tightened them up and the ski starts and turns over like a champ.

I've read it a thousand times on here to check ground/cables first, I guess this time I learned the hard way the vets on here don't recommend this for nothing.
 
Good thing you did check that, I have seen loose battery cables at the battery melt the posts right down to nearly nothing. Although yours was on the starter, the point being that a loose connection acts like a highly restrictive resistor and can cause phenomenal amounts of heat. Starters too have fallen victim to loose connection meltdown. Nice to hear you figured it out :)
