not driving

Fwd/Rev contactors come in and go out right away, no codes on dash. Lift ok, battery good, 50.2 v. Also dash has side buttons, how do I access codes.

Check drive motor brushes. Turn steer wheel 90° and see if one or the other motor operates. Check contactors over for all 3 sides of tip condition. Check shorts to frame. Nothing higher than 18 volts. Brake switch on hand brake leaking.

You say 50.2 volts that sounds like surface charge have you put meter into battery cables and checked under load ? Sometimes the battery will show a charge until you turn on key and try to use the lift and then you can see it drop drastically

"Komatsu FG18SHT-20 - thanks to the Gold and Silver Award techs for their generous help -...I replaced the cam and crank sensors with Hitachi CPS0003(23731-6n206) and CPS0008(23731-6j906) ones and there is no change. I wanted to ask if I have a separate LP gas controller..."

Fact of the week
In 1923, French tennis player René Lacoste was promised a crocodile leather suitcase by his captain if he won his next match. He lost the match but won the nickname "the crocodile" which he had sown onto his tennis attire. Ten years later he launched the first polo shirt and Lacoste, the first brand to feature a logo on its clothing.
