Potential solution to electrical problem

What's the alternator pushing out?

[TnRiver46]

I think at this point I may just replace stator and see if that does it . @galyonjsays he doesn’t like throwing parts at things but at this point I think we’ve reached a dead end

Sounds cheaper than an alternator

Well it’s not a true alternator but I think it’s pushing out nothing, although in ohms it’s only reading 1/10th of an ohm out of specified range

Me thinks stator and alternator do the same thing, but a stator is spinning magnets inside the flywheel that generate electricity. Then the rectifier converts it to Charging power for the battery. I want to say they are kind of pricey

I hate it, but I think you're right. Worst case, changing the part doesn't change the symptoms, and you just return it.

Me thinks you should stay with lake home renovations, they seem to be more fun...LMAO

Hahaha we put a new hot water heater in there last month, works great!

I've kinda had a blast doing this. We joke that it's like a King of the Hill episode.

It's always good when you can work with friends or even siblings. 

The only thing bad about it is, trial and error can get expensive.

The beer at the end of the day usually tastes great though. ?

Alternators, essentially, combine the rotating magnets from the flywheel, the poles from the stator, and the regulator/rectifier assembly into one self-contained unit, and then the whole thing is run off a pulley. Otherwise it's really the same thing.

Lemme know how you guys make out. 

Good luck boys.

[Jigfishn10]

Just curious, did you find the problem?

My bet is still on stator, haven’t tried replacing it yet . I’ve just been fishing out of my other boat and ignoring the problem. You know me ....... hopeless fishing junkie

No wonder why you're working 3 jobs...?

Throwing some luck you're way that it's an inexpensive issue. Although that might not be a good idea. I was with dad yesterday and he said: "Son, if you didn't have bad luck you wouldn't have any." I still love him none the less.

My shallow water rig was hand me down from papaw with a harbor freight motor so it’s inexpensive and of course the most reliable . Pull cord, who needs stators and alternators???

 

and I’ve always got the canoe ready to search and destroy

Honestly, boats with electric start should have pull cords as back ups. Don tell be they can't do it.

There is a rip cord under the cowl of my merc but I’ve never attempted it.......

Update: extremely friendly and generous forum member @galyonjordered a stator and rectifier for me off the interweb. He got it several days or maybe weeks faster than the marine store could get their hands on it. Hopefully one or both will be the solution, my guess is the stator was bad

????? to galyonj. Good luck TN46

[galyonj]

 

For real, though; I just figure if we're to the point of throwing parts at it, let's get it over with. I'm mad at your boat now for defying me. ?

[Jigfishn10]

Good luck guys!

Thanks! 

 

We're finna get this thing done tonight. Soak the flywheel in PB Blaster, fix the power wires for the console depth finder, R/R the stator (and maybe the regulator, but I anticipate sending that part back), and check every fuse and wire in the charging system (again).

Buy enough parts to throw at it and eventually you might find the problem.

I guess the concept of trouble shooting parts before replacing them doesn't work.  

Never saw where an output voltage check of the stator was very looked at, or even a resistance check, which is not as reliable as voltage check.  

I see a whole lot more blown rectifiers than bad stators and it's more than simple enough to check the stator voltage to the rectifier. 

Rectifiers are usually blown by shorts and arc's, like when connecting jumper cables etc.

Stators are usually blown by running bad batteries.  Then never fully charge so the stator is running at max all the time until it finally overheats and burns out.  A good one is usually and nice reddish copper color, bad ones are usually burned black.  There are rare times a wire just opens but they are normally burned.  Stators are not cheap.

 

I guess I'm too old fashion, I like being fairly confident a part is bad through trouble shooting and isolating it to the part before I go through the trouble and expense of replacing it.

I think we’ve tested them both about 1000 times, but we have rectifier also. I would imagine the strategy is to try it first  and see if the voltage no longer drops while running 

 

the way I see it we’ve trouble shot for about a month now, how much more trouble can we shoot?
