9 amp or 16 amp stator

[RRH31978]

Had some issues with the voltage regulator and stator. Voltage regulator melted a few wires together mainly just the wires from the stator. ( 2 yellow wires) I tested stator and it tested .21 ohm the range is .16 to .19 so figured the stator is shot as well. Planning on replacing voltage reg and stator but not sure if I need a 9 amp or 16 amp stator. And does this effect the voltage reg depending on which one I choose?

I was planning on getting a CDI stator because of heat issues that I have heard about with the OEM stators. While I was digging around on the motor testing the stator I noticed that the wires coming off of the trigger are a little bit dry rotted so I figured that I am going to replace the trigger as well, while I am in there. Just do not want to have to do it after I do all of this.

I did not think of this before I ordered the voltage reg so I got Quicksilver 8M0084173 voltage reg.:facepalm:

Need to replace a stator not sure if I need a 9 amp or a 16 amp and does that affect the voltage regulator

if you have a regulator its gonna be a 16 amp......

 

[RRH31978]

Ok thank you Dukedog! I was not sure if it would be different. Would you suggest I get the 9 amp or the 16 amp stator?

I have a bank charger hooked up to the crank battery so charging is not going to be a major issue.

 

[Dukedog]

does your motor have tha regulator?

 

[RRH31978]

Not sure what happened here I went to post with the original question and it appeared here two times IDK

 

[Dukedog]

if it has a reg. ya need tha 16.. no reg. it will use tha 9..........

 

[RRH31978]

I just got one yesterday. Quicksilver 8M0084173 voltage reg

 

[Dukedog]

but did it have one originally from production?

 

[RRH31978]

Sounds great! Thank you very much! How accurate is using an Ohms meter on a stator in your opinion?

 

[RRH31978]

Yes it had a voltage reg originally. I cross referenced the number on the one on the outboard and came up with that one

 

[Dukedog]

will be tha 16 then.. justa note.. tha 16 can be run without a reg on most of tadays rigs.. with good battery maintance and if you run any electronics at all... its something you can figure out for yourself.. i never ran a reg with any of my junk (all 16 amp) at all but i ran electric fuel pump on all of 'em so i had a constant draw.. that makes a slight difference..................

What instrument would you use in lieu of a meter?

 

[RRH31978]

Have no clue just keep hearing that an ohm's reading from a multi meter is not reliable that I should use a DVA and test the voltage

 

[RRH31978]

Thank you Dukedog I am learning more as I go.

 

[Dukedog]

ya have ta have a dva attachment for tha multi meter.. most manuals give instructions on which leads go to what color and what voltage "should be" at different rpm's.........

here's a quote from a dva manufacture that kinda explains it.... hope it helps.

Often our customers are only equipped with a common multimeter, this is a good start but useless as you cannot read peak voltage output.
Stators may fail in various ways, most common is the windings shorting to ground either directly or to the coil that interfaces with the ignition. But there are other ways. Coils can short internally which gives good resistance but essentially fewer windings giving low voltage output.
The other way a good stator cannot provide power is if the rotating magnets in the flywheel are dead.
We finally have come out with the tool that you can simply attach to your multimeter and will allow you to test peak voltage with your common multimeter.

How it works
A DVA adaptor is also known as a peak reading adaptor.
Small engine ignition systems use permanent magnets to make electricity. This electricity travels down the wires very quickly and in "spikes" so to speak.
What a DVA does is capture those "spikes" and allows a standard digital multimeter to read those voltages.
Without a DVA adaptor, a multimeter will either record a low voltage, or no voltage at all.
Power sport ignition systems work on "peak" voltages, which is why a DVA is known as a "peak reading" adaptor.
Multimeters read average voltages, not peak, so that is what our adaptor allows you to do.

Ohms and Voltage are 2 completely different tests, and both need to be used.

And a DVA is an adapter for a meter. Ohming a stator is more a continuity test checking for an open. If it's not open and is a good stator, the resistance or Ohms is almost a short because it's just a long piece of wire.

A meter with a DVA adapter is for measuring the output of the stator or other fast reacting voltage. Without a DVA a meter doesn't have the ability or speed to measure fast changing voltages.

sure will be a good thing when all this "corona" stuff goes away and everyone gets back ta normal......................
