    If the Trinity Highway Industrial Equipment winch won't operate, first check that the power cables (+12vdc and ground) are securely connected between the truck's charged batteries and the control box. If low voltage is suspected, check the voltage to the ground at the winch to prevent premature damage to the motor. Also, the winch will not operate if the voltage drops below 10.3VDC (±3%) for 12VDC systems or 20.6VDC (±3%) for 24VDC systems. Charge or replace batteries as needed and ensure the truck's alternator is charging all batteries. Parking the truck on a level surface may help, as a steep downhill slope can prevent operation. Finally, ensure the limit switches are positioned correctly and adjust them if needed.

    If the Trinity Highway Industrial Equipment winch operates intermittently, it might be due to low voltage. While the truck is running, use a DC voltmeter to ensure the voltage does not drop under the minimum value during operation under load. To resolve this, increase the power cable gauge or shorten the cable length between the battery and the TMA.

    If the Trinity Highway Industrial Equipment winch motor is running hot, it may be due to excessive use. The winch is designed for intermittent use, so allow sufficient time for the motor to cool down between operations. The cool-down time will vary depending on environmental conditions.

    Winch solenoids chattering in Trinity Highway Industrial Equipment is caused by a poor ground connection. The winch solenoids are grounded through their mounting brackets. Contact Customer Service if the bracket is poorly grounded.
