Could a sh775 kill a stator?

[posplayr]

There's plenty of hearsay and "empirical evidence" on this forum . Do you want his brother to certify himself as a Polaris "service writer" to post the same thing?. I can't imagine why DohcBikes makes this up. It is what is for what it is worth.

It is pretty clear he is a troll seeking attention. His only evidence is that he changes out parts based on what his brother told him. He probably can't even describe what the differences are between SHUNT,SERIES and MOSFET R/R's!

Thats neat. Im not a cabbie but i know how to drive. You know why engineers and those that work in the field often have a hard time getting along? Because one of them thinks they are superior and doesnt consider the person with hands on experience.

Like the solid state power box. Noone wants it because noone needs it. Its overthought. Just like this regrec deal.

Why you all have to be so close minded is beyond me. Keep kicking out double what you should for rrs it doesnt matter to me anymore.

Not at all. I like opinions. I think that bobrogers looking up of a recall (here: http://www.thegsresources.com/_forum...92#post2348892) is useful information - doesn't it specifically apply to your info brother's reasons why they are replacing these (Thanks bob, even if I am on your"ignore list" too.

My brother has been a service writer for a polaris dealership for several years. They replace the exact reg/reg you guys recommend on this site all the time because they regularly fail and ruin stators. it's not any better than any other, and arguably worse. For the past year they have been recommending mosfet regrecs (aftermarket, which is not their norm because they are a dealership) and have concluded that they are superior.

what is your proof? Lay it out for all of us to read so we can make an informed decision

however, WILL get you into a discussiont and maybe that's what is wanting more..

Loads of insults in here, rather than facts.

Start a technical discussion.

As everyone should know, the increased failures – let's assume for a moment it's real, not just anecdata – seen/reported by Dohcbikes' acquaintances could have a zillion of other causes:

1. Faulty batch (for whatever reason)
2. Counterfeits
3. Incorrect handling during transport (very unlikely)
4. Incorrect application (R/R ratings given by manufacturer differ dramatically between uncooled/cooled application).
5. Principle of operation is worse than Shunt style (this has been hinted at in here)
6. The SH775 isn't engineered well to begin with
7. There's a difference between how Quads are used, and how bikes are used.

Personally, with my limited EE knowledge, I don't understand why 5) even came up. Also, I don't think Shindengen would still exists if 6 were to apply.

Furthermore, I presume that the R/R's on a quad are statistically under more stress compared to a bike; since many quads are used to get various work done (hauling stuff, winching, etc) and spend more time stationary or in a low-speed application.

posplayr already has taken a somewhat scientific approach by polling the GSR about their SH775 experience.

Dohcbikes, can you please provide more data? We're getting nowhere otherwise.

Also; if I understand you correctly, you're saying shunt-style regulation is superior to series style. Can you please elaborate, in a technical fashion please. From what I understand, the regulation used in the SH775 works by triggering SCR diodes at the correct phase angle, until then the stator windings will be left open – as opposed to shunt, where the windings will be essentially short-circuited.

It seems like a total no-brainer to me.

I started a poll in your honor.

I currently own four 80s GS and one 70s. I've owned and disposed of more than that many. In the last decade, I've only tested the voltage on one and found that it was charging correctly. I've only had a couple that didn't show indications of overheating at the stator bullet connectors and R/R outlet bullet connector. Some connector cleaning, and connector elimination (I prefer a soldered joint now) and a used Shindengen shunt type R/R off of a Gold wing is all I've ever done. I've never had a stator go bad. I bought a replacement stator once because when I performed tests, I did not have proper connection between the probe and the stator connector.

I believe that some of that is probably luck, but not all of it. It may be a factor that I rarely cruise at over 65 mph, so I'm rarely at the full output of the stator for extended periods. I generally tour on back roads.

Yes, I've seen that too at the bullet ends and I'm a fan of those Goldwing/Silverwing R/R's too... I should have added that I've replaced all batteries and 2 of the original R/R with these old Honda ones, while another bike has been running very well with an R/R replacement the Previous owner had put in...( I keep meaning to write down the model # !!) but I did have to rewind the stator on this particular bike too 6k miles further on...it had actually been repaired by a (quite -clever) bridging of a short! ...but I figure this R/R was put in at the same time as the repair and is working well for me now.

which brings me to that difficulty of analysis:usage. Previous and Present. I don't do much city driving either and it never gets that hot here for long Nor do I run heating accessories or extra loads...so I am not stressing the system except occassionally.

PLUS with three licensed bikes on the road, it's going to take longer to build up the mileage on any one of these rebuilt systems to say exactly what I did that is a fail, longterm.

I'll just keep an eye on my little voltmeter stuck on at the cluster. And every so often I think to put my finger on the R/R....warmish is ok, HOT is bad.

So has any one here had a sh 775 fail? I replaced two regulators in three years and this spring installed a 775 with good results. Granted I only put on about 4500 miles this summer.

Quit beating around the bush and actually answer the question - what is your proof? Lay it out for all of us to read so we can make an informed decision

Why you all have to be so close minded is beyond me. Keep kicking out double what you should for rrs it doesnt matter to me anymore.

I love how you say we are so close minded but you refuse to do what I asked for. I think you are nothing but hot air.

[jsandidge]

Still no facts, but plenty of arrogance. His claims must be true. Might makes right.

Dude, the guy is a electrical engineer.

[Who Dat?]

Too busy working on my bike to care. Have a good day!

i have no reason to care. Have a good night.

Bye now.

That's at least THREE times, how many more before you actually make it happen?

[bobgroger]

More proof that you are overcomplicating and overthinking this extremely simple system. And maybe obsessed.

The sh 775 goes bad at least just as often as any other reg rec and the gs issue is the suzuki regrec.

Stators don't care how much power they put out. They either can or can't keep up and they couldn't care less either way. The bulk of the power distribution and management is handled by the reg/rec.

shunt regrecs have been working since the time of cave men. except suzuki shunt regrecs.

Bye now.

Sure glad they implemented the Ignore list......

Thanks for the sage wisdom; unfortunately you are about 30 years too early.

my grandpa's been riding Harley's since the 60s. Him and the old farts he runs with all take their bikes to an old long gray haired dude who guarantee hasn't seen one bit of tech school but knows the ins and outs of Harley Davidson and can fix this sh!t blindfolded. even the stealership techs will call him and ask questions. your not impressing me that you and your bro run a multi zillion dollar stealership service dept. the only time any of my gramps buddies hit the h-d place is to buy t-shirts

Not surprised your grandpa rides one, or wears the t-shirts. They are built soft and slow for older folks.

1941 tech is not too tough to grasp. Nothing against grandpa or Gandolf the harley mekanik.

But they're LOUD... so they SOUND FAST... which is extremely COMPELLING!!
