95 Club Car DS Jerky Acceleration

[toolittletime]

I am having a problem with jumpy acceleration. Starts off smooth, but as pedal is applied it jumps up faster.....kinda like skipping a gear.
Is there a troubleshooting guide on here I could use, and where should I start to diagnose this problem?
Thanks jerky

What does the battery pack voltage drop to from a dead stop to full throttle?

Haven't checked that yet. Would I need to check that before cleaning the contacts on the potentiometer?

I would start with checking the batteries and the battery cables.

Batteries and cables are new.

Check the battery pack voltage like I mentioned and post the results.
