Troubleshooting Guide
Prior to diagnosing your Power Plow snowplow, verify that all connectors (plow and vehicle wire harness plugs, headlight
adapters, control box, fused hot lead, draw latch switch, solenoid ground wire connection, coil wire lead harness, plow
headlight harnesses) are free of corrosion and are well lubricated with dielectric grease. Insuring that all connectors are
in good working order will save time in determining your snowplow’s service needs.
