While this may not be the ideal solution compared to replacement by a new, higher capacity MOSFET unit, someone may find the option to be useful. The rectifier can be combined with the regulator action from the original style VRR.

Rectifier replacement innovations
The GS alternators have three-phase stator output which is typical of older style automotive alternators. This would allow the use of a separate rectifier such as one of the older style Delco Remy 12SI units should one have a malfunctioning rectifier section of the VRR: http://www.ebay.ca/itm/Delco-Remy-12...item35b43b2b6c

Norm,
Those you have shown are quite useful.
Have you seen these yet? The current rating, form factor and cost make these quite versatile.
I have received two of these and intended making up a test circuit for the bike alternators one day. Not sure if if I will ever get around to doing it, but that is what I told myself when I ordered them.

Thanks, Matchless.
I've been looking at those and wondering if they would have the capacity. Please keep me informed as to your deliberations.
I do note that many diodes which are rated at 10 amps., for example the common coaxial ones, are not heat sinked so it would be difficult to imagine that they would survive in an under hood service. Have a rectfier from an ND 42 amp alternator on the bench at present which has one open diode but will see if a top hat or stud mount can be fitted.
Someone will likely chime in that this is not very useful strategy for replacing a GS VRR as there are so many off the shelf units but one always learns something through these processes.
Best,

It's really quite simple. You get the problem fixed for 30 or 40 dollars and move on. I don't see why people obsess over how powerful their RR is, or anything else. It powers the bike and keeps the battery topped off. End of story. The Honda variety happens not to short out and cook the stator in 20 minutes. They also have a sense wire which when properly connected to a stable voltage source will regulate far better than just looking at the output from the RR itself. And it has 65 mm mounting holes which lines up perfectly on our GS mounts.
But if someone wants to hook up o-scopes, talk about series this or that, pound copper pipe into heatsinks, have 10 ground wires running back to the RR, and put relays all over the bike they can go right ahead. I'll be out riding around on my GS.
I tried to engage the debate a few years ago on this but was ordered out of the room.1981 GS650G , all the bike you need
