A/C Wot Cut-Out Relay

  1. Disconnect WOT cut-out relay harness connector. Using an ohmmeter, check continuity between relay terminals "A" and "C" and "B" and "E". Continuity should be present on these circuits.
  2. Using jumper wires, apply battery voltage to relay terminal "C" and ground to relay terminal "A". Continuity should not exist between relay terminals "B" and "E" while relay is energized. If continuity is not as specified, replace defective WOT cut-out relay.
