So Batteries were knackerd - I've had them replaced with brand new - I just thought chasing faults was a bit pointless until that was sorted. So a rather expensive excersise later, brand spankers across the board. Now I still have my Fault code history so I assume there's a sub battery/memory somewhere. My Hydraulcs fire up and down far quicker than before and no fault code or stops are triggered but I still have very slow drive. I've adjusted the Mag pick ups (x2) for the steering position and I now have the wheel indication/location back. Is there a way to clear codes (if only for a short time) to assess if my drive motor can move fwd/rev normally to at least provie that is ok and it's more ont he fault code/control side? I'm not getting very far withfinding competent people who'l plug in and diagnose. Hold a few buttons down, press brake pedel twice kind of affair to clear codes?
