Series Regulator Source SH775

[salty_monk]

I'd really like to see what on a scope... Posplayr also suggested to me that a decent clamp meter might be able to show the necessary info, you wouldn't get the nice graph obviously but you could physically witness it.

You are basically looking for when it goes open circuit.

Dan,
When you compare a Shunt to a SERIES R/R you should see much less current in each leg of the stator with the SERIES. I plotted the comparison I observed between the FET and CF a while back.
So all you need is for something to measure average AC current. Most cheap AC current clamps are designed for 60 hz only. At 5000 RPM you will be looking at 500 hz for an 18 pole stator. So the question is whether an AC clamp has any effectiveness at this frequency and even if not accurate can it compare the SERIES to SHUNT R/R on a relative basis at least.
A bunch of ifs

So we need to find a budget version of this Fluke.... (Actually this is not expensive either at $105.)

No, that one does 50Hz (Europe) and 60Hz (USA).
Your best bet would be to find one that works on military aircraft (600 Hz).
This one would probably work: 400 Hz clamp meter
Just don't rev the engine quite as high.

Maybe you missed this bit on that page... Or maybe I'm reading it completely wrong! (I'm a know enough to be dangerous sort of electrical guy & I think I am reading volts & you were perhaps concerned about the current).

AC Volts (50hz - 500hz) Ranges: 4V, 40V, 400V, 600V



There are plenty of Fluke models that will do 400hz at their limit on current (such as the 321) as well as amprobe, klein etc.

Fluke specs:

Range: 0 - 400 A
Resolution: 0.1 A
Range: 0 - 40 A (Fluke 322 only)
Resolution: 0.01 A
Accuracy: 1.8% ± 5 counts (50 - 60 Hz)
Accuracy: 3.0% ± 5 counts (60 - 400 Hz)
AC Response: Averaging

If you can measure using one of those at 400hz (at less than 5k rpm) then perhaps I'll get one if EBay can turn one up cheap enough...

[koolaid_kid]

You are correct, I missed it. That would be what you want.

I have a Fluke 333. It might be good enough for relative measurements.

[salty_monk]

Fluke says you need the 337 for variable speed drives but it has to be worth a go if you've got one on hand!

Well I installed my used SH775 today and rewired a lot of the charging system and grounds, and it's charging like a dream now! 14.4 volts, no problem! about 13.6 just a little off idle speed. Relief... This unit is so much larger than the unit I pulled off of it, tiny unknown replacement with a 1990 manufacture date. Old unit with old corroded wiring and connectors (non-original) would charge at 12.2 at all rpm's above 2300... charging AWESOME now!

[salty_monk]

I stuck one of these on my bike yesterday.. (straight plug in for me).

It fits, reads etc exactly the same as the FH010 & the FH009 that I have as far as charging voltage etc.

Now to find someone with a clamp meter / scope...!

Why would a RR affect engine temps??

It doesn't. The engine generates far more heat burning gasoline than the stator does generating electricity. Simple physics.

It is a stretch to suggest the stator raises oil temperature above what the engine does no matter what the regulator was doing. Other bikes have a dry stator not bathed in oil that use the same regulator (Honda CM400 ex) and if the stator actually got THAT hot it would burn up in no time.

Interestingly enough these Honda bikes don't suffer from stator failures and their SDG regulators never fail no matter how bad the connections get. So another myth is busted that corroded connectors break stator or regulators. Corroded connectors just make it hard to keep the battery up but don't "kill" regulators.

Using an overkill regulator isn't going to hurt anything as long as it's wired properly and mounted securely. The costs for the regulator is much higher than the SH-232 or SH-532 and there is the matter of a wiring harness to contend with. But to each his own. I've moved 300+ SDG regulators in the past few years and I think they are working fine these days.

All good points. I think I like the operating principle of this design more than the actual amount of improvement it will offer. For $65 it was a cheap upgrade from stock, which is what I have right now.

Thank you, I suspected as much.

Duanage is making generalizations and can not accept the truth. On GS1100E's that are hopped up there is a noticeable drop in operating temperature. It has been documented here and independently confirmed.

I don't think Duane has an 1100E and is basing his presumptions on what he has observed from his 550. Ignoring oil coolers, any 4 cylinder bike is going to have a similar capacity for dissipating heat. Given the hp diff from a small 4Cy putting out 40-45 hp, v.s. a 1100E putting out 130-140 hp there is a marked difference in oil temperature .

So I noticed that the 4012941 part number on my SH775BA on my regulator now mostly brings up one that IS NOT what we are looking for, but rather a replacement RM Stator brand MOSFET regulator/rectifier for Can-Am's and Yamaha's that is mostly grey/silver in color as opposed to black on the Shindengens. So be careful not to buy this one if looking for a 3 phase series style R/R. Maybe it is just listed as a replacement for the SH775, but I see a ton of ebay listings when searching for the part # on mine for my wife's bike.

I did find another source for the SH775, search for SH775AA 278002021 for SkiDoo BRP Spyders, also says in the current ebay listing "2011 Grand Touring 600 ACE. This regulator will fit tons of vehicule in the Bombardier line up like Spyder , Outlander , snowmobile and this will also fit some Honda , Yamaha & Suzuki vehicule"

Well, I guess I'll join the Doubting Thomas Club. The PM charging systems on these bikes put out at best 400W. This is a third of what my hair dryer puts out, and I can't imagine any circumstance when this would make a difference in the operating temperature of a gasoline-burning 80+ h.p. engine, considering that a single h.p. is defined as 746 watts.

If it's 'independently confirmed', I'd like to see the details and the control of variables.
