Can anyone help with more current ratings for the regulators? It will help to make the list more useful to all.

**Matchless** · 12-26-2008, 12:46 PM

Honda type charging

Here is a schematic to show how Honda (CBR1000RR 2004) uses the 5 wire regulator. A 6th sense wire was also used on some models of regulators and can be connected directly to the battery or via a switched supply (ignition) if the model of regulator draws some leakage current from the battery when not in use. Both of these types can also work very well on the Suzukis.

Suzuki older charging system

Here is a schematic of the older Suzuki type charging system, it has not changed much. Note that the W/G and W/R wires are plugged into each other. This used to be the older method of switching that phase into the circuit when the headlights were switched on. This was later removed and connected as shown below as the wiring, connectors and switches in this part seemed to fail after some time. Correct this on your bike if not already done.

Here is a later (early 1980's) type regulator showing the actual switching of the 3rd phase for the headlights. Around that time the bikes still had the wiring running to the front but was just plugged together as is shown on the wiring diagrams.

Later Suzuki charging sysytem

Here is a schematic of a later Suzuki(VX800 1990-93) charging system, not much has changed except that the later regulators, regulate all three phases and use a better/modern type of internal regulation with an ignition switched sensing wire. Delta type stator configuration for the USA was most likely for the headlights always on requirement, giving slightly higher current at lower RPM's ( my guess only).

My VX800 is wearing a Honda R/R, from a Sabre 700... works great, and it was nice that there was already a switched wire in the harness for the sense wire! I also mounted it on the side of the bike where it can get some airflow, instead of barely an inch from the exhaust pipe.

I never could find any solid info on why the US had Delta vs. Wye stators, but it doesn't make any difference to the regulator.

Here is the ultimate regulator

The new Shindengen 50A rectifier using FET's for shunt regulation. These should be bullet proof!! Has anyone used this? It seems as if the practice of a special sense lead was only used for a short while and discontinued on newer models.

**posplayr** · 12-27-2008, 01:53 PM

SCR's begone

I might be reading something into that schematic as to physical location of the R/R, but if that device is located right across the battery and has good physical connections with only the single inline fuse then a separate sense wire is not necessary.

The sense wire is mainly needed because of the circuitous routing of the typical GS harness between the R/R and the battery.

Notice that the device only has 1/2 of a full wave rectifier with means it is likely to only drop 1/2 as much power in those power Diode devices. Also the SCR's are now replace by FET's . It is also possible that the lower 1/2 of the missing rectifies bridge is implemented in the control function of the FET's.

If I remember correctly, if the FET's are turned on during the negative cycle of the respective legs from the "magneto", then the device acts just like a full wave rectifier but without regulation. As the FET "ON" times are extended into the positive portion of the magneto outputs, there is a reduction of the output voltage because now a portion of the positive portion of the waveform is also being shunted to ground.

This works because there is a much smarter controller/logic in the R/R (see "Cont") to switch the FET's in sync with the magneto waveforms. This device is probably so much more efficient to hardly dissipates any power and you can hang it right off the battery eliminating the need for a sense wire.

Best R/R on the market today is the Shindengen FH012AA used on the late (06+) Yamaha FJR, R1 among others
It is a MOSFET controlled device rather than the crude SCR type and a 50A rated device.
MUCH better voltage regulation and runs cooler too.

Jim,
I just took it for granted that because most of the advice on the forums was to rather fit a Honda unit as they were more robust and that they use a 6th wire for sensing purposes, that these were then better. On some Honda forums it is quite amazing to see the problems they also have with the charging circuit.
When I tried to find an actual Honda charging schematic I found that most of those I have use 5 wires and that for a short time Honda did actually use a 6 wire one with a sense wire, but they have done away with that quite a while ago it seems. (If someone knows otherwise please correct me). I actually was under the mistaken impression that Honda used that aproach quite widely and that it was one of the reasons for their reliable charging systems.

For example the Suzuki VX800 in the early 90's also used a sense wire, so maybe that was the time Honda also used that approach, meaning that Shindengen made them during that period. They seem to have been phased out again since then and most if not all are back to 5 wire. My guess is that there either was no long term advantage above the non sensing one or problems when age and dirty connections started.

I have to venture a guess that Honda most likely used an "over engineered" unit like maybe a 35A capability, but specified for say 25A and this made them more robust. Again these were built for all the UJM's by Shinengen who also manufacture the electronic parts so they should not have been using poor quality parts in Suzuki and better quality for Honda models as some models were used as OEM parts on various brands.

I would not think that 30 year old technlogy electronic components that have been in constant use and maybe abused over that period, even if it was a Honda unit, or specifically because it used a sensing wire (maybe later discarded as not successfull) would really be a good idea to fit as a reliable replacement, except from a budget point of view when new ones are exhorbitantly expensive.

The use of FETs is quite interesting especially replacing the one side of the full wave rectifier and so also reducing the component count and at the same time reducing the failure posibilities. The footprint is quite small and obviously it will not be running at high temperatures when working hard, being 50A rated. Again Shindengen manufactures the controlling IC and most likely have one that is not sold to anyone, but just for their own assembly plants.
I have also seen a schematic using triacs in place of SCR's, but do not know what advantage there would be.

As previously described 6 wire is not the "end all and be all". If you take the basic SCR based shunt regulator that Suzuki installed on the GS it had several problems most which have been described here. In comparision, the Honda units are very similar, but seem to have been designed for larger power dissipation (physically larger) and with the 6th sense wire they at least were not as prone to voltage fold back as I have described as associated with resistance between the positive leg of the R/R and the battery. The circuit topology is probably very similar to GS models otherwise and that is about where the benefits end between the Honda 6 wire v.s. the stock GS models.

The primary issue with the simple permanent magnet (rotor) AC generator on many motorcycles is that there needs to be an efficient way of shunting (shorting) power to ground when the generator is putting out more power than the system wants to use. Shunt regulation is brute force in a sense and so is generally limited to situations where there is limited power to deal with.

On power circuits like this you want to minimize components that are dropping voltage and carrying the full supply current. The diodes in the full wave bridge (GS and 6 wire Honda) are dissipating power and carrying the primary power. The SCR control was also doing the same. Both of these devices (diodes and SCR) are not particularly efficient. The diodes drop about 0.8V in saturation and the SCR is probably well over 1V. A FET can carry teh same current but will drop much less voltage than this as the FET on resistance is essentially zero.

On the positive side, the Diodes and SCR need very little to control the on/off of current conduction. The SCR has a reference it needs to provide closed loop regulation. On the other hand the FET's have no intrinsic voltage sensing and require "smart" on/off signals from a "Controller". Now a days this is much easier to do than back 30 years ago. so the R/R can be implemented at much higher efficiency because the Controller switches the FET on and off as required and the FET's never drop much voltage when they conduct so the system produces at least 50% less heat.

The new FET based regulator could have been implemented with 6 FET's but that would have been overkill and potentially created safety concerns so at least 1/2 of the rectifier bridge was left in.

This type of FET technology is not that much different to motor controllers on modern synchronous DC motors. The FET technologies allow controller efficiencies to get close to 95% whereas with the older bipolar technology efficiencies might be closer to 80%. This new FET R/R will probably find much wider usage as time goes on.

Why does the FET technology not benefit from a 6th sense wire? This new FET controller can probably be mounted directly across the battery as the thermal consideration as less severe. As such the sense wire doesn't really provide any benefit. Basically the wire lengths between the R/R to the battery should be as short as possible. That means avoiding running the R/R positive through long harness runs and through many fuse box crimps if possible.

The install note suggested a single run from R/R through an inline fuse to the battery on the plus side; a similar direct connection for the negative side.

Hope this is clearer.

Man, all this electrical talk is WAY over my head. I'll need to go get my Dad to translate.

Quick question: how are we supposed to find or test the capacity of a particular unit?

**four_shot** · 12-27-2008, 11:50 PM

Wow...my heads spinning.....Glad you guys are being proactive. AFIK my R/R is functioning well (definately need a new battery), but it is nice to know my options when it finally lets go.

Any threads on gutting the factory R/R and swapping better internals in? I want to keep my bike as close to "resto" as possible.

If I even have a one peice R/R (79 gs850gn)

I have looked at this, but the space is just too small for new components that are available over the counter. The potting used to encase the components also make it very hard to get at them and in most cases impossible. You basically need to fit a 3 phase 200V 35 Amp bridge rectifier and 3 SCR's inside this with a a few other small components and be able to bring 5 wires out.
Keep well.
