Hey, thanks for the info. My 22 rk 750 has had no eps since about April or May, just turned dead left if you let go of the steering wheel. No help at all from hisun in Texas other than tell me to take it back to rk after the mechanic had already told me twice he had no idea what was wrong with it. Had to have a starter replaced at another dealer closer to home and they said they would check on hisun fixing the eps. Been about 2 months and haven't heard anything. It's a decent sxs when it works but I would advise anyone to buy another brand and save a huge headache. Where is the diode located and does it just plug in? Thanks for the info. Sorry you're in the no eps club.
