Hi all.

I would like to ask your help.

We have a Still R70-20 truck. (serial: 512079000017, year: 1999) It had a problem. When you started the truck it went with full speed. It was going with the same speed even when you did not pressed the accelerator pedal. It did not have regenerative braking. We changed the RPM sensor (if I knew it well it's called tachometer). Actually it was a sensored bearing. It was hard to got this part cause everybody said it should has a hall effect sensor not a bearing. Anyway now the speed problem is sorted out.
But a new failure appeared. When you go forward, than stops, and you want to go backwards (the direction indicator shows you are going backwards) sometimes is still go forward. And we still do not have regenerative braking.

Does anyone experienced a problem like this before? Or maybe an idea what could be causing this?

Thank you for your help in advance.

Best Regards,

András
