Testing the kill switch principle
(Open to stop / Close to stop)
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 and that the cord is not
attached to the mechanical kill switch, meaning that the kill switch
is in the position which the engine will not run.
Infinite resistance measured:
You have a Open to stop (OS) Kill Switch – Use Blue wire and Grey
wire on the xHUB to connect to the two existing kill switch wires
from your engine. See wiring diagram for Open to stop on page 28.
Close to 0 (zero) resistance:
You have a Close to stop (CS) Kill Switch – Use Orange wire and
Grey wire on the xHUB to connect to the two existing kill switch wi-
res in your boat. See wiring diagram for Close to stop on page 28.
