Best Reg/Rec Upgrade

Ok, so it's quite clear that the OEM r/r and wiring harness are weak links in a pretty reliable chain. I've read a handful of posts on the subject and found a handful of upgrades that can be done.
The question- What is the best R/R / Harness upgrade? (Considering cost, reliability, availability, minimal hackery,etc.) I know allot of you guys know what's up!

In my opinion, there is no "best". Someone can/will always have great experiences with one brand, and the next guy has a bad experience.

You can certainly read through this thread, where there are several brands listed.

Its like any other electrical system. Do the maintenance and you wont have the problem unless something goes very wrong. Cant predict rubbed wires nor melted wires, but you can keep the stock r/r going by doing the services needed. Stator should not fail unless over drawn so keep farkles to the minimum. The weakest point I can find is the bad decisions made in choosing connectors and calcing load to heat dissipation of the individual pins. Eg the r/r connector melts as it handles 35amps but the connector is only a single pin for all that and should have had 3.

Be proactive not reactive. Replacing the r/r because you feel its weak based on forum posts is not proactive as it will fail eventually.

 

My vote id for the yamaha R1 unit. Wires up easy, huge heat sink, heavier duty. Than do the rest of the system and don't let battery get discharged so it needs heavy charging while riding.

And add a voltmeter to monitor system condition.

Actually I used a Hayabusa unit do it it being mounted on its own heat sink plate. A little doctoring required.

I just bought and installed a Shindengen SH775 R/R, the series model (same size as FH020) because of my LED lights, will fit on OEM bracket with a small mod, bracket is required because it supports part of the fairing system. If you go this route, this is what you need to do:

Small flat head to mount to frame, long flat head to mount R/R, enlarge holes to countersink.

 

How do I get my hands on those connectors? Went to website, can't find prices or way to order any??

Check site again, it is all there.

 

My r/r has the the yellow stator leads, two green ground, two red positive, and one black sensor lead. What happens to the black wire is I use the 775 kit?

The black is a ground wire, the two reds are different gages, the smaller id the sense wire. Run the black and two reds to the battery. The stator leads just hook them up in any order. it doesnt really matter much, since we dont have schematics for the stator nor r/r to make the system balance properly.

 

Ok, so what about the green, aren't those ground?

Im going to have to pull your schematic to make sure as the green wires should go to frame while the black goes to batt neg. We use the same r/r on the 6th gens just different connector and color codes.

I am at work tonight, so ill respond by 1500pst tomorrow with the exact answer for you. If you have the 5th gen service manual, the schematic is in the back chapters on electrical.

 

When I installed my SH775, it did not have the fifth lighter gauge black wire my stock R/R had.
In looking at the wiring diagram in my manual, it shows it (actually White/Black on diagram) going to Engine Stop Switch to supply +12volts.
I replaced two reds and two green 12v DC output wires with #10 wires directly to the battery. Since 5 pin connector was not being used, I jumpered the Black connector to the Red +12v connector to supply 12 volts to Engine stop switch (Red/White wires were still connected to battery).

Wire on left of connector goes to Engine Stop Switch.

Diagram also shows it going to bank angle sensor as well:

 

What needs to be done with the red/white wires? Do they just go straight to the battery, or do they supply power to something else as well?

They are still hot, tape up end of connector to protect contacts, and tuck out of way.

 

Could I utilize the single red/white wire to connect the white/black to it after the fuse? Or would I be cutting off another circuit at that point? I'm trying to get my hands on an accurate wiring diagram at this time, that way I can figure it out myself rather than continuing to ask silly questions.:/

That's what I did.
