I have a 2012 RZRXP4 with //stage 2 kit. I am getting a OV 17.5, the check engine light comes on and the EPS stops working. If I keep driving it will go off and everything starts working fine. Keep driving and it will come back. The Check engine Code is 0 on the left 3 in the middle and 168 on the right. I have a yellow top Optima battery. It sometimes die when I come to a stop but not all of the time. I check the ground on the battery and on the frame, They look ok. :sad:

All of the 1K's are suffering from voltage regulator issues. Polaris hasn't come up with a fix yet, besides throwing new voltage regulator at the affected machines. Some of the components have over voltage protection, like the tail lights, EPS and gauge cluster. That's why they quit working intermittently. Seems like the stator puts out more voltage than the VR can handle. They need to go back to the drawing board and beef up the VR.

Well we found out, that they replaced the voltage regulator , problem persisted, so we came to find out the there were 2 bad relays, not to mention corrosion on the relays as well as where they are inserted, after cleaning everything, and switching the good relays around, check engine light turned off power steering light turned off and regained use if it, so Polaris is sending all 5 new relays, being that the possibility of the faulty voltage regulator may have ruined them by over charged current.

Well the regulator was the problem. I replaced it today. I first check voltage to the battery to make sure it was not the ECM giving false over voltage. it was not. My meter showed it was over charging. I Ohm the stator and it was good. That left the regulator. I replaced it and no more over voltage. Thanks everyone for the help.

This code can be caused by several factors. The wiring harness to the coil is faulty. Inspect the wiring harness going to the coil and ensure the wiring is in good condition with no bare wires and no broken wires. The other issue could be that the coil is shorted. To test the coil use a digital multimeter and measure the resistance between pins 1-2 and 2-3 of the ignition coil. The resistance should be approximately 0.4 Ohms. If it is less then the coil may be faulty.

Thank you for your advice! Before replacing anything I checked on the wires that ran to the coil and they had a cink in it. I fixed the cink and problem solved! 👌
