electrically testing regulator/rectifier module

[ccottle]

My manual suggests the proper way to test the regulator/rectifier module is to tie off the Sea-Doo to a fixed pier in the water, rev the engine to 5,000 rpm and test voltages and currents under this operating condition. Please! that seems overly complicated.

I have access to laboratory quality electrical and electronic equipment and know how to use the equipment if I just had a guiding procedure on how to test the module.

Does anyone know of an electrical stimulus and respnose measurement procedure that can be used on this module? It's the 278001554 part number. Seems if you have access to equipment like this, there should be a quick procedure to test this module.

Anyone?

Wow.........

Wow, I haven't seen that procedure before. What manual are you reading from?

If your looking to test the magneto and regulator/rectifier..........all you need to do is have a cheap, digital multi tester. You can hook your ski up to the hose, start the motor, start the water, then set the meter on 20 VDC or higher, depending on your testers range. Then, put the positive and negative on the battery post. IF all works, you should have anywhere from 13.8 to 14.2 VDC on the battery terminal. You don't have to rev it to 5k for this. If you only get 12 VDC while the ski is running, you got a problem.

Thanks for that. My manual is a Clymer manual. From the electronics point of view, a rectifier module should be easy to test as well as a regulator. The module itself is no trouble to remove. There are a total of 5 terminals...one has to be the common (reference or ground by other names). Really...a simple power supply, power load and meter should allow me to test the thing if I had a schematic and some specs.

I get the impression these things fail quite often.

Thanks for your reply

Hey ccottle. It will be fine to run the engine out of the water as long as you have the cooling/flushing hose hooked up and water running through while engine eis running. Do not let it run on the hose for than 5 minutes. Jet pump bearings and shaft are normally cooled by the seadoo being in the water. So, on the hose there is no way they are being cooled.
All the "Seadoo" manuals recommend doing this test and never mentions being in the water.
Also there are no static test available, due to internal circuitry.
There are many other test for the battery charging coil though.
