Hi, I'm working on a RC 3000 with a plugging issue. If the machine is plugged the right side motor arcs from the brush area, key has to be cycled to restart. The motor, contactors, RECs have been replaced. NOTE; this is a hand me down project, I can get more info about it if necessary. Thanks

Thank you to all for the help. It was the capacitor. It threw me off because it was only happening going forward and turning left. Thanks again.
I'm leaning toward the D or dual motor contactor. It should pull in when you plug. A good way to test is to put a cable on both sides of the contactor to simulate a closed contactor, then drive the truck in a straight line. This truck is not going to make turns on one motor with the cable on there, but it will tell you if a D contactor is the problem. Contactor will close, even at very low speeds, when plugging if it is working correctly. It must have good tips also. Don't rebuild it, replace it, if it is bad.
Make sure your new motor brush leads are tight and all springs are set in place. new motors are sometimes shipped without testing
Sorry I don't have a handi-man meter, just code scanner.
I'm sorting through parts lists. Looks like all screw in recs replaced, however 1,2,5 have not. Drive motor, every travel contactor. Thanks.
how about d contactor?
sounds like rec behind operator
Is there a Status code on the display when the unit shuts down?
If you have a HANDI MAN tester, check the 4 recs under load.
when you say the "recs have been replaced" are you including all the #3 and #4 recs (plugging and fly-back diodes)?
