then the voltage at reverse input should be checked. Depending on whether the
controller is programmed to non-inverting or inverting throttle polarity (refer to Chapter
1 section 4.9), then on a correctly functioning system the voltage at reverse input
should be as below. If the voltages are incorrect then check the wiring and connectors
to the freewheel switch.
Non-inverting throttle:
P2 - pin 9 : 0V ± 0.5V to drive in reverse
5V ± 0.5V to drive forwards
Inverting throttle:
P2 - pin 9 : 0V ± 0.5V to drive forwards
5V ± 0.5V to drive in reverse
If the voltages are correct and the trip is still present, then the controller may be defective.
Refer to section 5.
4.6 Motor or Brake Becomes Very Warm
The motor will become very warm if it is being overloaded. One cause maybe that
the solenoid brake is jamming. To check this, refer to the vehicle manufacturer’s
instructions.
4.7 Batteries Discharge Very Quickly
The batteries can discharge very quickly for several reasons, these are listed below.
• Worn or damaged batteries - check battery condition.
• Charger defective or incorrect charger being used - check charger operation
type (refer to vehicle operating instructions).
• Incorrect batteries being used - refer to vehicle manufacturer’s instructions for
correct battery types.
• Solenoid brake jamming - see section 4.6.
The ambient temperature has a significant effect on battery
capacity. Therefore, if the temperature is lower than normal
the vehicle’s range will be reduced. In this situation, the
TruCharge battery gauge still gives an accurate state-of-
charge reading.
