Click steps to track your progress.
Verify the nominal operating voltage for the drive reverse coil.
Measure the voltage across the terminals of the drive reverse coil when it should be active.
Inspect all wiring and connections leading to and from the drive reverse coil for damage, looseness, or signs of overheating.
Measure the resistance of the drive reverse coil itself, comparing it to specifications or a known good value.
Check for continuity across any protective fuses or circuit breakers in the drive reverse coil circuit.
