Ever seen this for a reg/rec

[Redman]

Two full wave bridge rectifyers (two stator phases on one, and 3rd phase on the other). Outputs in parallel.

Not seeing what is regulating, other than if that is a zeiner diode...on one phase of the stator .. not the DC out ..

Cant really predict how well it will work, but Trev says is good.

I wish the picture were still here so I could ogle this curious creation.

Do you mean this one?

So this is on the 81 gs1100e I just picked up. The po said it was on it when he bought it ten years ago. Rob (AZR) and I tested the charging system and it was dead on.
So Rob asked me to post this as he tought it might cause some debate here...

While this charging system modification is a testament to the PO's resourcefulness, and the GS charging challenges, it is not something that anybody really wants to mimic. As has been described at length, while the cooling provided by the large heat sink might generally protect the R/R there are two major problems with the design:
1.) It does nothing to protect the single stator winding that is being controlled
2.) If the single winding does not shunt enough current for the loads (say a headlamp is left off) then you will boil the battery and possibly burn your harness ground wires.

It would be far better to buy one of the following in ascending order of preference:

1. a used 3 phase SHunt R/R (shunt all 3 legs)
2. A used Honda 6 wire shunt R/R
3. A series R/R (SH-775 or Compufire)

Can anybody find the ground wire for this R/R? I can't. I can only imagine that the groudn is provided through the harness on a small wire grounded to the solenoid tab.

I wouldn't try to duplicate this same system either. Better R/R designs out there. Especially the newer series unit.

[posplayr]

I agree the side plate and the heat sink is r/r(-), butThose don't do anything to connect the side plate to battery/frame/harness

Other than the stock blk/wht wire from wiring harness that may be under there on the solenoid mounting bolt. ... and we know how marginal that can be.

Oh, I now see that is what you said in post #18.

You will correct me if I am wrong, but if you "ground" one leg of a stator, you are grounding them all.

You will correct me if I am wrong, but if you "ground" one leg of a stator, you are grounding them all.

Depending on whether the stator is wound in a "Delta" or a "Wye" configuration, grounding one of the three legs will disable either one or two legs, but not all three.

In the Delta wiring, you will be grounding one side of each of two windings, leaving just one winding unaffected.

In the Wye wiring, you will only be grounding one leg, leaving two sets of windings unaffected.

I suppose what I am saying is that grounding in this manner "replicates" a ground fault in a stator and has the same effect.

[81GS850]

So how did the PO get this to live for 14 years if the system is that bad? I guess it did alright.

[Gorminrider]

Yes, I love stuff like that. Ain't broke-don't fix! It's covered by sidecover so Trevor's Collector plates aren't an issue. Nowadays maybe to buy all those bits would cost as much as an R/R . In a neglected situation I 'd be a little worried by corrosion per dissimilar metals with all the aluminum hanging out but it's been taken care of.

It failed at least once, perhaps more times. Who knows how much it was even ridden in the last 14 years and nobody has looked at the stator. Any more variables needed?

If you want to understand what "grounding a stator" leg is and is not go read the manual (GS1100E for example). It describes the current flows when "shorting legs" of the stator.
