B2650 stalls out when pressing pedal or engaging PTO???

[DV2650]

My B2650 will start just fine, I can increase RPM with no issues, hydraulics work just fine, however, if i engage the PTO or press the pedal forward/backward, even slightly it will stall out. I thought perhaps it was the seat safety switch, so I jumped it with no luck, even zip tied the switch itself, and ohmed it out, everything checked out. I did replace the diesel as it didn't get used much this winter, replaced the fuel filter. Replaced the safety switch, and still no luck. I'm at a loss. Anyone have any suggestions on what to try next?

Please have a second look at the seat switch.

It is how your rear is engaging with the seat switch. It is a pad velcro'd to the back of the seat. Do you have a down coat on? I have put a thin piece of Styrofoam under mine. Since I regrettably gained about 10 lbs, I don't have as much difficulty. Also it doesn't like really cold weather.

Follow the WSM to figure out what's going on, because the most common is the Seat switch, bit it could be mutiple other things causing it too.

I’d check the circuit out at the OPC controller. If the circuit checks out good then replace the OPC controller. A bad controller will act exactly like a bad safety switch.

Before you replace the $320

OPC, CONFIRM it's getting the 'seat switch' signal first !
Follow the wiring diagram in the WSM Electrical section , you might have an open wire.
Since you bypassed the seat switch, it's not the switch ,sounds like a wire's been cut.#030 is the 'controller' that's $320 !! I'd hate for you to shell out $320 to replace a good OPC and when installing the new one see the cut wire that IS the problem.

Check the wires going to (or from) the seat safety switch... something is up with it.
