How do you test a mercury switch?
Touch the probes to the two leads when you put your multimeter into continuity-test mode. The angle at which the switch opens and closes is determined by tilt. The switch is not continuity when pointing down.
How does a mercury switch box work?
The switchbox monitors trigger voltages for each ignition circuit. As the magnet approaches a trigger coil, trigger voltage for that coil rises, and peaks as the magnet as almost over top of the coil. Its voltage reverses as the magnet travels away from the magnet. The rising voltage is key.

How do you test a switch box?
Test for Power
Remove the screws on the switch cover plate, and pull off the cover plate to expose the switch wiring. Without touching any wires, test each wire in the electrical box with a non-contact voltage tester. Also, test each of the side terminals on the switch by touching it with the tip of the tester.
What does a trigger do on an outboard motor?
Your outboard trigger tells the switchbox when to “fire”. The inner ring of your flywheel has magnets which pass close to the triggers coils. Each time the magnet passes, the trigger sends a low voltage “signal” to the switchbox.
How do I test my outboard CDI box?
Step 2 – Testing CDI (Cold Test)
First take the leads of the multimeter and connect them together. If you are using a digital multimeter then you should hear a beeping sound. Measure for continuity between all the ground and the various other points. If your cdi is working well, you should not hear any sounds.
How do you know if your outboard stator is bad?

How do you test an outboard stator with a multimeter?
Remove the cowling of the outboard to begin a static or resting test. Using a digital multimeter, you’ll be measuring resistance in ohms across the three coils that comprise the stator. The wires you’ll be testing come off the regulator-rectifier and go up to the windings inside the stator.

What is a mercury switch on outboard?
A mercury switch is an electrical switch that opens and closes a circuit when a small amount of the liquid metal mercury connects metal electrodes to close the circuit.
What causes a boat motor to lose power?
Boat Engine is Sputtering and Losing Power
You most likely have a filter problem or fouled plugs. That could be why your boat motor is losing power. Solution: Replace the in-line fuel filter.
Where is the trigger on a outboard motor?
Nestled in with the stator under the flywheel is the trigger (or timer base). Probably the most overlooked part of the ignition system the trigger sends a signal to the CDI unit (power pack or switchbox) and tells it when to release voltage to the coil.

Can you bypass a CDI box?
It is possible to bypass a CDI module on an ATV, but it should be only a temporary action.
Can a CDI box cause no spark?
Sometimes, a bad CDI does not cause sparks at all. Again, when a CDI box is about to go bad, it can lead to misfires, issues with starting, rough running or even stall the motor. These mentioned symptoms can be confusing and one has to be careful before concluding that the problem is with the CDI.
