how to test generating coil output

[Daryl]

can you test it if you dont have the bombardier ignition test?

 

[ILLNESS]

are u talking about the stator? or the ignition coils??

 

[Daryl]

don't know exactly the service manual says generating coil going to the ignition coil.

 

[kustomkarl]

Bombardier Ignition Tester is required to test the trigger coil and ignition coils.

on the 95 spx it also used to test the generating coil according to the service manual. but i need to know if there is a way to test the generating coil using a multi meter and how.

Do you have a seadoo shop manual? If not here’s an idea for you. You could join as a "premium member". As a premium member you can down load a authentic seadoo manual from the seadoo manual library. In the library is a variety of manuals for almost all years and models. You can view as many as you like on line as a PDF file, or download it and print it for your personal and private use. There are operator manuals and repair manuals for you to do your own repairs on your seadoo. The repair manuals have everything from troubleshooting, repair procedures to winterizing. It contains wire diagrams torque specs and pictures for disassemble and assemble instructions. In the spec sheets it tells everything needed to maintain oil changes, spark plug gaps, carburetor rebuilds and impeller wear ring tolerances. Click on the "Seadoo Manuals" link at the top of the page for more details. If you need any help or get in a jam, we are always here to answer your questions too. Premium members get priority when it comes to getting quick detailed answers.

You can tesrt the battery charging system function by monitoring the battery voltage while running. If the battery voltage goes to something like `14-14.5V at 3000-5000 rpm, then it is OK. If it stays at a voltage near what it is when not running then the charging system is not working.

Here is some information on the charging system;

When the engine is running, set your voltmeter for 20 VDC and put the leads on the correct terminal posts. With the engine running, you should be reading anywhere from 14.5 to 14.8 VDC. (typically this test is done at 5,000 rpms) This tells you your charging circuit is good. If the voltage is higher, the regulator is bad. If you’re not showing a charge and you've replaced the rectifier, you may want to do a test on the Magneto/stator/charging coil. If you’re not a premium member and you don't have access to a manual, this test will be hard to do without it. There are 2 fuses that protect the charging system. Check the 15 amp fuse in the MPEM and the 15 amp fuse between the solenoid and the MPEM.

The magneto and stator create un-regulated AC current. The "rectifier" converts that AC to DC current and the regulator maintains the current between 14 to 14.5 volts DC for the engines operation and charging circuit.

I hope this helps.
