Regulator/rectifier

Post by Cirerite » Sun Sep 04, 2016 10:34 pm

Hello all! Tired of messing with the points on my 62 superhawk. New coils and electronic ignition and bike runs ok. Still needs some tweaking. Wired in a new regulator rectifier. Wired it in with the incoming wires for the old rectifier. Added a wire off of the ignition for voltage when ignition on as per the instructions. Not sure why it needs that... Red wire to the battery. Green wire to the ground. Leaving two wires which I connected to the Brown and yellow which were previously attached to the original rectifier. All per the instructions. No charge at all on the battery... Any thoughts?

Can you please tell us the maker of the unit. Perhaps one of us has had the same experience. Have you checked your stator AC voltage? Pictures are also very helpful too. I wanna be helpful here but not much to work with yet.

Sparckmoto.... I'm sure it has already been posted somewhere, how do I check the stator. Thanks for the input!

The alternator on these bikes doesn't have a sensing circuit.

Reg/Rec.

Post by Billiam » Tue Sep 06, 2016 3:18 am

Hi Cirerite, Just travelled the same path. No expert but this is what I worked out.
The original system just gave a small trickle charge to the battery as there was no regulator.
This ran off two phases of the alternator leaving the third phase (pink) to supply current to the ignition for emergency starting.
However the solid state Reg/Rec. needs all three phases to work properly. This phase is on the pink wire. Access to it can be found in the bunch of bullet connectors covered by the sleeve on the main loom going down towards the alternator. Unplug it and then run a new wire from it (the alternator) back up to the R/R from it leaving the pink to headlight switch disconnected for the time being.
With this set up on my 64 305 it gives a nice steady charge to my "tired" battery.
I have bought but not fitted yet, a switch to throw the current to the emergency start circuit if needed, when I've worked out just what it is.
Hope this helps.

You've got a couple of points wrong. No such thing as "emergency starting". Two of the wires from the alternator go to the rectifier, the third wire from the alternator runs to the ignition switch on the CA models and to the light switch on the CB and CL models. With the lights off it does nothing ( basically a dead end wire), lights on it is connected to one of the other legs going to the rectifier adding needed amperage to run the lights.

It's single phase, not three phase a/c current. One leg is the brown wire and the other leg is the yellow wire, which is combined with the pink wire at the light switch for more output. Permanently combining the pink/yellow wires will produce maximum output, lights on or off, the regulator will take care of the voltage level. Connecting the voltage sense wire to the ignition circuit(instead of the battery) will insure the coils get full voltage even if there is resistance in the main switch or the wiring.
