Locate the existing PTT relay: Consult your engine's wiring diagram or service manual to identify the relay's mounting position.
-
Remove the old relay: Disconnect the electrical connectors by gently pressing release tabs, then unbolt or unclip the relay from its bracket.
-
Inspect wiring and connectors: Check for corrosion, fraying, or damage. Clean terminals if necessary to ensure solid electrical contact.
-
Position the new relay: Mount the replacement relay in the same orientation and location as the original.
-
Connect the electrical terminals: Plug each connector firmly onto the corresponding relay terminals until you hear or feel a click.
-
Secure the relay: Tighten mounting bolts or clips to prevent vibration-induced loosening.
-
Reconnect the battery: Attach the negative cable to the battery terminal and tighten securely.
-
Test trim and tilt operation: Turn the ignition to the "On" position and operate the trim/tilt switch in both up and down directions.
-
Listen for relay clicks: You should hear the relay engage with each switch activation, confirming proper electrical function.
-
Check for smooth motor movement: Verify that the trim/tilt motor responds promptly without hesitation or unusual noise.
-
Inspect all connections: Ensure no wires are pinched, and all connectors remain fully seated after testing.
