That is too low, You need to see if there is an issue with the throttle wires right at the MCOR 3-pin connector.

First verify You have approximately 5v on Controller pin #1 White/Black wire.


Disconnect the 3-pin connector at the MCOR and measure the voltage on the harness side.

Black/White wire should be the same as You measured at the Controller Pin #1.

Measure the Purple wire (meter negative probe) to pack positive battery post to make sure you get pack voltage.

If You do, change the meter to resistance 20kΩ.

Measure the resistance on the MCOR pins that align with the Yellow and Purple wires.

The resistance should vary from less than 1kΩ (Pedal UP) to more than 6kΩ (Pedal DOWN).

Disconnect the 3-pin connector at the MCOR and measure the voltage on the harness side. It has 1.1 volts

Black/White wire should be the same as You measured at the Controller Pin #1.

Measure the Purple wire (meter negative probe) to pack positive battery post to make sure you get pack voltage. Has pack voltage 52.3

If You do, change the meter to resistance 20kΩ.

Measure the resistance on the MCOR pins that align with the Yellow and Purple wires.

The resistance should vary from less than 1kΩ (Pedal UP) to more than 6kΩ (Pedal DOWN).
Resistance is pedal up 1.1 pedal down to floor 7.7

What was the voltage on White/Black-to-negative and the Purple-to-positive?

The resistance reading is right, if the the voltage on the white/black Controller pin #1 is correct you have one of those 3 wires pinched or bad between MCOR and Controller.

Double checked white/black only has 1.1 volts
Purple to positive was pack voltage.

Will go out and check wiring.

Where did You measure 1.1v, at the Controller pin #1 or at the MCOR 3-pin connector?

if not at the Controller, measure at the Controller as it could be bad.

Will double check it at the controller it is 1.1.

If You only have 1.1v at the Controller Pin #1 (White/Black wire) then the Controller is Bad.

Thanks Sergio for all your help to day. It is very much appreciate. If I keep at it I just might learn something.
