Hi,

I have this strange thing with a Komatsu FB16-1E 1996 with a Bosch control:

I had no drive, lift or steering, and the indicator counted from 001 to 009 when i pressed the accelerator.

I replaced the complete accelerator with a brand new one, (factory calibrated I suppose)). I now have this:

- When I press the accelerator the truck drives, lifts and steers
- when I loosen the accelerator slowly the wheels slow down
- when i loosen it further in the last 1/2 cm the steering motor goes on/off/on/off/etc.; about 1 second rithm. I get A09.
- when i loosen the accelarator completely and the switch is actuated and the wheels go full speed !!

I was very happy I followed the rules and had the wheels off the floor.

So when I don't fully release the accelarator the truck functions normal. Adjusting the potentiometer won't help, pressing the switch gives full speed no matter where the potentiometer is.

Who can help me solving this problem?

Anyone have a wiring or a workshop manual?

Thanks, Frits.
