Re: replaced rectifier and it still is not charging.

If you did the tests like said above, then it sounds like your stator is weak, and on its way out.

Re: replaced rectifier and it still is not charging.

My motor has a mis when running and the charging system is not working, would this be the cause of that as well as it not charging?

Re: replaced rectifier and it still is not charging.

If you are confirming that you get 0.00 ohms between the yellow stator wires and ground ... with then totally disconnected and motor not running ....then you have a stator short to ground!

I assume that means it is bad? and would be the cause of the charging system not working and the cause of my motor mis?

One thing that is confusing me is...per Joe Reeves instructions it said I should have NO reading between yellow and ground (isnt 0.00 a no reading) so how is it bad.

Re: replaced rectifier and it still is not charging.

No where in this thread have I seen where you actually checked the output to the battery. Have you done this? Measure the voltage at the battery with the motor off, then start the motor and check it again. As RPMs increase you should see an increase in voltage.

Yes, I have checked the voltage before and after I started the engine. It is the same no matter where I check it (i.e. at the battery or the red wire coming from the retifier) running or not at idle or reved.

The charging circuit as such will not affect the running. It is separate from the ignition circuit BUT the charging coils and the magneto coils are on the same stator assembly Maybe if there was a short between the two circuits the same fault could be causing both problems ... I dont know!

Joe is an experienced outboard techie but perhaps electrics are not his strong point.

With the yellow wires from the stator disconnected from everything else you should get a very low resistance between them.
BUT between either of them and ground you should have an infinite resistance. If you get any other reading between them and ground it indicates a short or partial short to ground.

From what you have said the stator coil appears to have a fault but before removing it and spending money on a new one I want you to be absolutely sure about these readings.

Re: replaced rectifier and it still is not charging.

I will retest and repost the results. The only reason I am thinking the two problems are linked is because the motor is not running correctly and the charging system is not working. I replaced the rectifier and the charging system is still not working, but I suppose it could just be coincedence... again I will repost the results.

Re: replaced rectifier and it still is not charging.

Ok, I have retested the stator...When I Put a test lead on the 2 yellow wires (which are disconneted and just hanging there) at the same time I get the same reading that I get if i touch the 2 test leads together and the meter has a constant beep.

When I touch one lead to a yellow wire and the other to ground I get no reading (same for both yellow wires).

when I put the meter on low ohms and connect a lead to each yellow I get 01.8 - 2 ohms.

If the stator is bad, I would like to order it tonight or tomorrow, so let me know asap, also is there anything else I need to get when I replace it if it is bad. I have done everything else I can think of to try and correct the way the engine is running so I hope these two problems are linked so fixing one fixes both....

Re: replaced rectifier and it still is not charging.

Do you have the flywheel off now? Just curious if the problems are related there may be something obvious shorting out under there.

No I do not have the flywheel off yet, I am having trouble getting it to break loose.

Re: replaced rectifier and it still is not charging.

Those meter tests indicate the stator is good. Low coil resistance...1 - 2 ohms...and not shorted to ground. Your previous post indicated it was shorted to ground.

Now here is the next test....yellows disconnected, start engine, read AC volts across yellows. I know you already did this and got 18 volts. If that is still the case, the stator coils that do the battery charging are good.

If you want to go a step further, and I do this all the time so don't freak out, you can wire up a trouble light to the yellows. Cut a household extension cord, strip it back, connect to yellows, plug in the light, start engine. It will glow dimly if the stator is putting out current. Your choice....but I do it as the final good, no good test.

I have repeated that test several times, with the same result each time. with that said...if the stator is "good" why isnt the charging system working when it has a brand new BRP rectifier???

Well....at least I'm not the only one that is doesnt know. :(:confused:

Re: replaced rectifier and it still is not charging.

I would recheck the R/R, new or not, and the wiring. There the only choices that seem to be left.

Re: replaced rectifier and it still is not charging.

The stator ohms should be 0.7+-.05.
Disconnect tach until you get system working.
Some stators have exposed windings, windings look burnt?
Some Stators incased in expoxy, is expoxy melted and dripped on block?

This regulator have purple wire? Purple wire hot with key on, cold with key off?
Regulator red wire connected to red wire at termial block, this red wire connected to starter solenoid?

Re: replaced rectifier and it still is not charging.

When you retest the stator, do it with engine at operating temp. If you can`t run the engine warm the stator with a hair dryer.

I am not sure how to check the R/R, I have replaced it 2 times now, the original one wasn't working so I put a used one on and it didn't work so I figured the used one was bad too so I bought another one NEW and the is no difference in the operation between the 3 of them, no tach and no charge, and the motor has a mis that seems to be an electrical issue.

No bench test for regulator.
