EH problem

Danny Steel · Jan 29, 2022

My 2012 tr270 has no drive or bucket movement
Sometimes playing around with the operate button on the display it will work for about 5 seconds.

Then all stops

I tried disconnecting the door and plugged in the bypass with no change

thanks for any help

It was working ok when I ran the machine again,
But after approx 5 min the emergency brake comes on and stops all hydraulics….then I wait a minute or 2 and the brake comes off and runs fine.
I noticed a loose battery lug , so I cleaned up the terminals and have it on charge in the shop….I’m hoping this is the problem

Those early machines had some issues with wire routing in the control handles. If you still have an issue after tightening the battery cable, I would pull apart the right handle and check the wiring for rub throughs, my guess would be your park brake wire is rubbed through.

It wasn’t the batter connection….also looked at the joy stick wires, they all look good
I’m wondering if it’s the display module

Check the connection where the lapbar comes down and contacts the switch. It will be behind you and on your left side. Try cleaning off the contact patch.
