Default Tomberlin Vanish Stutters

Hi,
I have a 2010 Vanish that has had a couple minor issues in the past. I am fairly electrical save but am missing schematics for this vanish or idea on the fix.
When the accelerator is pressed the cart sounds like it is grinding gears almost. However, having a bad battery previously made the same noise. I pulled 5 of the 8 this time and had them replaced. Changed out 2 of the battery cables.
The issue is still there.
I am reading 50. VDC from the lead + battery to the last battery in the loop.
I put the vehicle in neutral, its on jack stands still, and pressed the accelerator and it still barely moves. About the same speed no matter, high, medium or low electrical gear.

So first thought was check the fuses, they are all good.
Master fuse is good next to the motor controller.
I checked the motor controller and appear to be getting 25 VDC if I remember correct while the accelerator is pressed.
I know on the emerge series there is a fault light setup under the seat.. is there anything like that on the vanish.

The next step was to check the soilnoid beyond it just clicking and completing the circuit, which it is clicking. I took reading and saw the voltage drop while the accelerator was pressed.

I had a technician come out and say there is a speed controller more than likely in the motor he think it could be bad. How do I test this... I was unable to find a port for him to plug into.

Hello Did you ever figure out what the issue with your Vanish was? I am having similar problems but have not been able to figure it out. Not much info available on troubleshooting. Thanks

What do your batteries read with a load on them?

Wow I missed your post a long time ago. Still have same problem. Batteries drop down to 44 volts with cart jacked up and throttle applied. Noticed cable going to motor gets warm when running. All batteries read 6.2 volts after testing under load. Maybe controller or the motor is the problem? Not sure who can help troubleshoot.Please Help.

The Vanish had issues in the motor with the sensor bearing. If it isn't reading the speed correct, the unit goes into a creep mode.

Unfortunately, we have been unable to locate those even globally, but still actively searching.

I attached a 2012 vanish wiring diagram, which is fairly stable across the years.

Well if it is the Bearing and it becomes available,does the motor have to be pulled to replace? I guess without a replacement bearing I am not going to be able to use the cart.Is there an easy way to test to verify that its the bearing? Thanks for the fast reply.
