Hooked this up so I could run a heated visor. Have hooked OEM regulator/rectifiers up many times before for a 12v output. That didn't matter with this, it didn't even regulate the AC output my the sled. Fried both headlights first blip of the throttle, luckily didn't fry my Koso EGT's. Hooked old regulator back up and everything worked fine. DC wasn't stable nor was AC. Don't try and save the $10.00 over OEM on this one. No returns on electrical, out the $45.00 plus $55.00 for the Polaris part.
