shindengen question

[jimmyenglish]

Hi gang! I just recieved a Shindengen FH0020 from Jack at roadster cycles (great guy) and I'm wondering how to hook this up to the bike. I have a new stator as well. Do I use the harness plug and just ditch the brown wire or skip the harness plug and go straight to the battery with the 10 gauge, nicely crafted piece that came with the rr? Seems like the harness goes up to the dash and beyond?

 

Thanks everyone! Great forum as always.

Did you look here? From what I read you should have 3 wires to go to the RR and then 2 go to battery

Yes, thank you. I read that but do I need to use the existing harness connection?

Just leave the old regulator connector that went to the battery unplugged and taped so it can't short out to your frame or some other grounded spot. The other 3 wire connector on the old regulator is the stator wires. These wires will come from the engine case. Cut the connector off of these wires and install the crimp on connectors supplied in the kit. Crimp and solder these on. These plug into the gray colored side of the Mosfet as in the diagram. There is no set pattern for these just plug them in, they are AC (alternating current) so there is no wrong way. The 3 feet of red/ black 10 gauge wire in the diagram is supplied in the kit. You do have to plug these in correctly or you will end up with expensive smoke!!! So be careful when hooking these up

 

Sounds to me like you cut the old plug off, connect the supplied wires to it and plug it in.

I mounted my unit behind the bullnose so it was in the airstream (for cooling). On the left side ( as you sit on the bike). Then ran the red and black wires directly to the battery terminals with the 10 GA wire. This way the unit will monitor the voltage directly at the battery and not thru all the old wire harness. The wire harness is old and may have built in resistance due to it's age and distance from the power source. I think that the closer to the power source, it will result in better reliability. Mine has been wired this way for a year now with no problems. I can take a pic of the unit if you want to see how it is mounted. I mounted it to a metal plate which acts as a heat sink.

Hi Jim, yeah I would love to see that pic. I'm a little confused though with the old plug. I notice it has 2 Reds and 2 blacks. One red seems to dump out near the starter solenoid and then to battery. Where does the other one go? Thanks!

The original connector has 2 red and 2 blacks because the proper size wire did not fit in the plug contacts. The 2 red connect together and the 2 blacks connect together between the RR and the battery.

 

If you are going to run the RR wires direct to the battery, just make sure that you are not eliminating or bypassing the main fuse.
