2007 Throttle problem with alarm

[10A Rubicon]

I’ve got a 2007 Precedent. When I accelerate most of the time the cart will suddenly regen brake with buzzer. If I stop and start again with say 10% throttle and keep it at 10% it will usually run fine, but if I try to accelerate I will get the same braking and buzzer. If I start out at 75% throttle it will usually run fine, but if I let off to say 25% throttle and try to continue at 25% I get the same braking and buzzer.
As far as I know the cart is stock except for the MCOR, which I upgraded to a MCOR 3. It has worked fine with that until today, but it was a used part. Batteries are new. Any help would be appreciated. Thanks

Unplug the two pin connector from the MCOR (under the floor and connected to a linkage from the pedal) and jump out the connector with a paper clip or a small piece of wire. It will be a blue wire and green wire connector. If it runs with the jumper in place, your MCOR (internal micro-switch) has failed.

And if it is still hesitating, the micro-switch may be working but the potentiometer of the MCOR is faulty. One thing to try is cut the key of, fully depress the pedal 25-30 times and see if it works better. If it does, the MCOR is failing internally....

Thank you, I will give this a try.
