Help with Yale ERP20AAFE2380

I am having a problem with it.
When i push the pedal either to move it forward or backward it starts hiccuping and slowing it's speed but then it starts working normal.
I already switched the accelerator potentiometer but the problem persists.
The display shows no error.

Can anyone help me?

Hi rafael,
First you need to test the commutator on the drive motor, disconnect the battery and connect a test meter across the A and AA (armature) set it to continuity and manually turn one of the drive wheels to rotate the drive motor watch the meter and make sure that you have continuous continuity on the drive motor com if not you have a drive motor armature fault.
What type of GE controller is fitted on the truck thyristor, MOSFET / IGBT or sepex (I think it is a MOSFET / IGBT with 3 big blue capacitors with an NY logic) if you are not sue can you describe it.
Regards Shane

It takes years to build up trust, and only seconds to destroy it. controlelectrics.uk@gmail.com
