Installed sound bar Friday and didn't start the rzr till Sunday. Rode Sunday, washed it Monday and drove it down the street to air dry it, then popped up check engine light. Took it to the dealer and the code was "speed sensor not working". Replaced it with a new one and still didn't work. Oft it there for awhile and they call me a few hours later saying they got it fixed. He said I had low battery voltage? I checked my battery with multi meter and on the cluster and had 12v. Have anybody had this problem? Just hard to believe I had low voltage when the rzr starts just fine and is reading 12v. Just not sure if that's what it was.

I have no idea what they tested to come up with low voltage. I had the ignition wire from the sound bar connected to the battery because I havent bought any more wire to run it to my acc connection up to the front. Just kinda weird it spent days connected without running, and then ran it all day Sunday. Then the next day driving up and down the road then all of the sudden I lose voltage while driving? The only place I can get a connection to the bar is right at the terminals.

I never looked at the voltages when it set off a check eng light but when I was actually riding it on Sunday it was 12 something voltage. But I will check the vr tomorrow after work. I go back to work tomorrow and won't go on days off till next Wednesday , so I can't really go down and talk with the service guy at the dealership.
