POWER TILT RELAY INSPECTION
• Disconnect the power tilt relay connectors, and
remove the relay from the outboard motor to check.
Remove the power tilt relay (page 10-6).

• Switch the tester lead polarities to check the circuit, including a diode. The circuit is normal if there is
continuity in one direction but not the other. If there is continuity in both directions or in neither direction, the
circuit is abnormal.
