Bobcat A300 2-speed intermittently stops working. When I was troubleshooting it, it worked fine on the LH joystick (replaced 2 years ago), but not on the RH joystick. When I tried to activate it from the RH joystick, I received a 40-13 code (RH grip communication error). I checked all the connections, and have concluded that the RH grip has failed and needs replacement. My question is, with the RH grip not working, will that cause an intermittent issue with the LH grip not being able to put it into 2 speed? I have removed both grips, checked all connection points, no corrosion, no pushed back pins. I checked the connector at the 2 speed solenoid, same there, no issues. Any suggestions would be greatly appreciated. Thank you.
