Honda Regulator Modification

[duaneage]

I have had a few requests for pictures of the wiring tie-in I did for my Honda Regulator modification so here it goes. The Red and Black leads from the Regulator need to be lengthened, soldering and heatshrink is recommended for that, otherwise here is a quick pictorial of what worked for me



Here is a closeup of the yellow jumper I made to tie into the brake switch wire

Nice job!
I have also added a SH323-12 ( CX-500) and retained the Honda RR
connectors.
What model RR did you install?

I used a cx500 on mine.

1978 CX-500.

The bolt holes lined right up and the grounding wire was the same length as the Suzuki

Hmnn,
I actually remembered you and your bike from the ride. As my memory is fading with age, I am lucky to remember anything. The mind is the first thing to go.

so, I have a few questions with regards to this regulator swap:



Why does everyone do it???

What is the benefit/s of the swap?

Should I do it on my GS750B (1977)?

(I run a 90/100 watt H4 headlight)

The Honda regulator is a superior design and charges the battery better. Honda regulators are not really made by Honda, they wre produced by another company just as Suzuki bought regulators from a vendor. But the Honda features better regulation and a higher output voltage than the Suzukis. It is all a matter of design choices made by the manufacturer.

If your concerned about the health of the stator I would do the mod since the stator is more expensive and difficult to replace than wiring in a Honda regulator. I would expect the stator to last a long time with a Honda RR.

OK I got one of these from Ebay, it has 3 yellow wires to connect to the output of the stator, a red wire for the battery and a green wire and a black wire, which wire is for ground? The green or the black? I'm guessing the green one (industry standard for household wiring), am I correct?

Thanks so much.

The Honda R/R has the extra black wire that must go to a circut that is energized when the key is turned to "ON". Most of the suggestions are to connect it to the feed for the rear light. Make sure you use the running light and not the brake light wire. The Honda diagrams have the black wire connected to the coils or ignition. If you use the rear light it will energize the R/R if you ever move the key to the park setting. It probably won't hurt the R/R if you left it energized for a while with your key in the park setting but I don't know. The rest of the wires on the Honda R/R are three yellows that go to the stator, a red wire that goes to the battery and a green wire that goes to ground.

thanks so much fgh, that answers all my questions

See my pictures for the hookup, make a jumper wire to tie into the brake light orange/white wire.

Bumping to top. Love the pics. 8)

Doing this today, and just thought it could use a bump.

Sticky?
