[Jimmihs]

HI, I have a Seadoo Challenger 2000 from '03 ..My RPM counter has stoped working I have tried to find the problem by looking at the plug for the RPM counter but havent been able to find a solution.

Do any of you have an idea of what to to? :bigear:

Thanks in advance..

Pop the plug and make sure you have power, and a pulse from the engine when it's running. If you don't... chase the wires, and find out why. If you do... the gauge went bad. (replace it)

Hi, Thanks for the quick response ..To test that there is power i look at the Purple "Batery power" and the Black "Ground" to see that there is 12V right?

How do i test if there is a pulse? Do i look at the Black "Ground" and Grey "Tach signal"?

Hi, one more thing ..If it is the gauge went i need to buy part 32, right?

Yes... if you stick a meter in the power plug... you should see 12v when the power is on.

Checking the pulse is a little more difficult, but a "Cheater" way of doing it is to put the positive wire from your meter into the plug, and the black to a ground source. You shouldn't see any voltage. Once you start the engine, you should see some AC voltage. (or a DC pulse) The actual number isn't important... but you should see a change from stop to running.

If you have an O-scope, or frequency counter, you can actually check the pulse.


Finally, yes, #35 is it... but I'm sure you could find a tach for a fraction of the price on eBay. BUT... I'm sure you are going to find that there is an issue with the wires. The tach's almost never go bad... and when they do... you will see condensation in them, or the needle will be stuck mid swing. (the bearing shattered)

HI, now I'v had time to test and here is the resaults: please note that i have used a digital meter.

Look at the Purple "Batery power" and the Black "Ground" I see around 12V when the engine is on.

Looking at the Black "Ground" and Grey "Tach signal" I se around 6 when the engine is on.

Does this mean that the gauge is dead?

One more thing there is also a blue wire, what is that for?

Thanks in advance..

HI, I found this on the web at a good price, it is not for a Seadoo Challenger 2000 but it looks like it should work..

Seadoo part: 204470321 the one that is in the boat is 204470807

Any idea if this can be fitted my boat?
