January 10, Sean : Well, Universal parts can be extremely valuable in repair work due to their ability to fit such a wide array of vehicles. They can be especially helpful if looking for a component that has been discontinued by the manufacturer.

However, the uniqueness of each individual ignition circuit precludes doing the same with CDI boxes. Sean : Unfortunately, CDI boxes have to be built to the specific vehicle in question. In addition, the electrical aspects of the system such as the resistance and voltage of the pickup and source coils also vary widely, which will likely exacerbate problems from mis-matched CDIs, or make them not work at all.

The CDI boxes in these systems are not interchangeable. Us : What kind of repercussions could there be if someone uses a CDI box not originally designed for a particular vehicle model? Sean : If the power and signal inputs for the CDI are off, the system may not function at all. Customer questions Meet the staff New Post.

These terminals connect to the primary circuit, which is connected to the marine battery to create a charge.

This spark plug lead connects to the secondary circuit, which sends an electrical charge from a coil to the spark plug. This voltage gets transported to the spark plugs, where it fires up the engine. Turn on your voltmeter. You want to test the resistance, not current or amps. When working with the outboard motor, you want to turn the dial toG1 CDI bad or am I doing it wrong?
