I bought one of these R/Rs:

Regulator Rectifier CB750 F2 Nighthawk CBR1000F ST1100 | eBay

Looking to wire it up and there is a problem. I am using the connector from my burned out stock R/R, cleaned it out and the contacts are ready to solder to. I have my honda service manual and it kindly lays out the configuration of the stock wiring connector (P. 14-2)--

3x Y - AC
1x W - to rotor and switched power
1x B - to rotor & switched power
1x R/W - to battery +

But... the aftermarket R/R has the following wires:

3x Y - AC
1x R - to battery +?
1x B - Switched power?
1x G - extra ground

I understand where to put the yellow wires. But which wires do I send to the rotor? There is only 1 (apparent) positive output from the R/R, can it be used both to vary the rotor signal and charge the battery? Or am I screwed and this is in reality not a suitable R/R?

 

That manual you have ! is it for a Mark 1 (87-88) ?

Because it sounds like it and the mark 1 has different wiring for the R/R

89 - 99 , Gen2 and 3 have the config you speak of 3 Y , 1 B, 1 R & and a green ground to frame

So yours is a 95 1000f right ...... then the 3Y, 1B, 1R & G should work !

 

Mine is a 95. I have the service manual from this forum and I think it is correct for my model. Which wires from my r/r do I put to the rotor?

 

Ya know - I got goddamned confused so I went out and popped the tail and looked
at the Electrex RR 23 I have - sure enough there's a white wire in it !

So the one you have is indeed short a white wire - send it back

Also the red goes to the bat, the white and black goes back to the stator.

Got a new one on the way. Any idea how many mAh the bike draws while running without any head/brake lights or signals?

 

Hi YZ125 - An interesting question ( but really and academic one and of little practical value. Let me explain as I've had a little experience with this area.

For an example ....Lets assume your question is "how many mAh does the bike draw while running without any head/brake lights or signals and is in gear with out the RR connected"
I don't have an answer and Honda dont specify a "running" mAh figure because it varries so much. The varriation depends on engine speed (RPM).The higher the engine speed the the greater the draw. (this excludes for variations in age of the components being the Ignition Control Module, the Ignition Pulse Generator and the Ignition Coils.).

For all practical purposes, (to check if the components are working), resistance values and voltages are specified in Chapter 14 and 15 of the W/shop manual. This, I find, the best way for trouble shoot.

Sorry there is no definitive answer to your question.

 

Good reply. I'll keep track of my battery voltage after riding this afternoon and see what I get. Maybe if I have to wait long enough for a proper R/R I can get some real data
