Squeeze the control lever and test the voltage at U (wire
#27 & 28). When the output voltage varies with the
control lever but the motor does not respond and all the
tests above have been done, replace the motor.
With main power on, test voltage at terminal 30 (X) on
Relay should be 34 to 38 VDC. With switch on, check
voltage to wire side of resistor (Y). Should be 34 to 38
VDC.
With main power on, test voltage at terminal 87 (Z)
should be 34 to 38 VDC.
With main power on, test voltage at terminal 85 (AA)
should be 22 to 26 VDC.
