Hot Start Assist Relay

  1. Disconnect electrical connector from hot start relay. Using an ohmmeter, check continuity between terminals. Continuity should exist between terminals No. 1 and No. 5 without power applied. Continuity should not exist between terminals No. 1 and No. 3 without power applied.
  2. Connect battery power to relay (positive to terminal No. 2, negative to terminal No. 4). With battery power applied, continuity should exist between terminals No. 1 and No. 3. Continuity should not exist between terminals No. 1 and No. 5 with power applied.
