One-Touch Down Relay

  1. Remove one-touch down relay from relay box 1. See Figure . Check relay continuity. Continuity should exist between relay terminals No. 1 and 2, and between relay terminals No. 3 and 4. See Fig 1 . Continuity should not exist between relay terminals No. 3 and 5. If continuity is as specified, go to next step. If continuity is not as specified, replace one-touch down relay.
  2. Using a jumper wire, apply battery voltage to relay terminal No. 1. Using a second jumper wire, ground relay terminal No. 2. Continuity should now exist between relay terminals No. 3 and 5. If continuity is not as specified, replace one-touch down relay. If continuity is as specified, one-touch down relay is okay at this time.
