Electric Forklift Won't Move Forward or Reverse

Call a service person.

Good luck with that e-mail address. These are easily harvested by the spam-bots that patrol fora, which will readily bombard it with scam adverts for non-prescription pharmaceuticals and for ways purporting to get money out of Nigeria, rendering it practically useless in the intermediate term.

Sounds like a defective drive motor. Lynlynch is correct: get a serviceman to check it out.

Or, a defective foot pedal/controller. Call the man.

Vader, do you still have my tractor?

Yup, been using it to drag rebel fighters around to make them crash into one another.

Hey, even a Sith Lord need to be entertained once in a while you know .

Check Limit switch at reverse /forward pedal for correct operation.

It could still be the battery, assuming your meter is accurate, a 12 volt battery with only 12 volts is mostly empty......it should read at least 13 volts after a charge.....

At a guess, you have some defective cell(s)......

Charge each 12 volt battery separately and check the voltage while charging to be probably around 14 volts. Remove the charger and it should drop a bit and say about 10 minutes later, about 13 volts....

Its difficult to be completely specific with so little infos....

You say it starts to move when you press the pedal to start with.

Does it continue to move with the pedal held in this position before pressing it in further or does it stop all the same?

it switches off or stops to move?
