No eBay APP ID and/or Cert ID defined in Kunena configurationI'm starting to sound like a broken record regarding this topic since I've mentioned this information so many times...
A Shindengen SH775 can be found for $40 shipped off ebay and it's a SERIES type R/R which means it helps protect your stator from shunted return current overheat damage. A regular SHUNT type R/R returns all generator current that the bike doesn't consume back to the stator where it generates heat and can fry your stator.
The SH775 has grown in popularity so much that that the OEM's like Polaris that install these units stock have raised their prices from $70 a couple years ago up to $150+ now. Good news though is that cheap used units are readily available and they are super robust. You gotta be careful to not purchase a counterfeit though. That unit that Steve bought is one such unit. You need to buy a real deal SH775 which will have printing on the top showing what it is.
To find these units do an ebay search on "polaris rzr regulator" and then look for one where you can see the printing on the top.
If you can't see the printing message the seller and ask them to confirm. And don't buy a NEW unit for cheap because it's guaranteed to be a fake.
