If not/ Then
Perform battery discharge test.
Verify the chrager/process
Verify wire/connection quality
Verify primary voltage at Pin 5 & 17.
If BRF is found on the primary
terminals, replace solenoid.
Verify solenoid function. Check wiring.
To verify: engage solenoid at high
pedal. Voltage should start around
1-2 volt. As the pedal is slowly
depressed to the floor, voltage should
rise to around 48 volt. If extremely low
voltage is observed, replace the
controller. If immediate high voltage is
observed, replace the motor.
