Re: Temperature buzzer test

Unplug the tan wire from the bullet connector near the thermostat.
The end that goes to the helm touch to ground.....you should hear the alarm.

Re: Temperature buzzer test

Thanks Gary,a couple problems though.I do not know where the thermostat is on a boat motor.I do on a car though but that does no good..Also I will have to wait for the boy to get home as I cannot tell colors either,seriously..Anyway if I cannot figure it out I will take a pic of what I think is the thermostat and then maybe go from there...Thanks

Re: Temperature buzzer test

Thermo switch on this motor is at the top of the exhaust cover, would be on the left side of the motor looking at the head.

Re: Temperature buzzer test

Be aware you have only tested the buzzer & wiring, not the actual thermal switch.
