2010 gem need help

Just changed the throttle and batteries when you push throttle down the main switch clicks off then resets won’t go don’t have any codes any more but won’t move any ldeas

Not without codes. Possibly a wrong or bad connection could drop out and reset any code. Does display go out?

No display stays lit it resets after about 30seconds this switch is in the middle of dash l think it is called contractor switch

If contactor pulls in when key turned on, then drops out. Throttle switch is not working.
By chance this is the same problem as before changing throttle?
