Topic: CB550 Charging system SHU232-12 R/R question

[links56]

I have a 77 cb550 that I made into a bobber. When I got it all the harness and wiring components were hacked up and not on the bike. I tried to wire up the original system with the separate Regulator and rectifier and the rectifier was bad. I had a SHU232-12 regulator and rectifier combo so I wired that in. My question is, Is the the SHU232-12 intended for a permanent magnet alternator? Right now I have the field hooked to my ignition switch so it puts out the max. I think it is a shunt type R/R and It would regulate the full output from the stator. Its putting out 14.5v or so at 3-4000rpm and if you slowly drop the rpm's the voltage will drop to 13v or so then it will just drop out and my meter starts bouncing around. I have not run it like this long. Any guidance would be appreciated. Thanks.

Others here have run that unit before with reliable results. You can search that model # and you'll see the threads and wiring schemes they used.

That was close. dang I think that model would be better for me. I'm sure this will work somehow or if i could find any documentation on the SHU232-12 I could figure it out. I can't seem to find anything, just people selling them. Thanks though.
