Testing the kill switch principle 

Testing with multimeter

You can test the kill switch principle by connecting a multimeter to 

both cables from the existing mechanical kill switch. Make sure the 

multimeter is set to measure resistance. See picture on  

page 37 for reference on how to measure.

Infinite resistance measured: 

You have a Normally Open (NO) Kill Switch – Use Blue wire and Grey 

wire on the Boat Unit to connect to the two existing kill switch wires 

from your engine. See wiring diagram for Normally Open on page 39.

Close to 0 (zero) resistance:

You have a Normally Closed (NO) Kill Switch – Use Orange wire and 

Grey wire on the Boat Unit to connect to the two existing kill switch 

wires in your boat. See wiring diagram for Normally Closed on page 

39.
