RESTO Sea doo Gtx rfi 951 Not Revving past 3k

[Kirk Sharplin]

Just bought a Gtx 951 and it would not get over half throttle without it cutting out like it was hitting rev limiter and the battery light was blinking I checked the voltage to battery and it was not charging at first so I checked the stator it checked out so I put a new regulator on and I'm getting a charge now but I still am stuck with the same problem it runs great a low rpm but not at high any help would be appreciated thanks

Sounds like the system is passing AC, and making the computer go crazy. I would look at the regulator again.

When I put my meter on battery it is at 12.2 and when it is running volts increase to 12.9 when I get to when it starts to cut out at about 3000rpm is this in spec? The stator I'm getting about 65acv out of and no continuity to engine ground with .7 between the wires and I read that it is in spec how do I check to see if any acv is getting to computer?

Also I want to mention the battery light stays on and when I reset it, it will go off but comes back on in the matter of about 3 secs when it is running

Sure sounds like a bad voltage regulator to me.

I tried unhooking the red and black wire from mpem with a good battery and no difference it has got me stumped , just sitting on a trailer it hits the rev limiter at and 3200rpm with 13v at battery

The regulator I got was a aftermarket but it shows to be working fine and I'm getting no acv to battery

On these I don't think you can pull the wire like on the old ones. Running on the trailer will tell you nothing other than it starts so don't use that as an indication of anything.

What will put a rfi into limp mode? Any sensor or anything because everything I have checked is good any other ideas ?
