charging system help, problem ive been working on with progress but no cigar

Sounds about right with a fully charged battery.
Shows regulator is working and not over regulating or under charging.
You need an amp meter next to see charge rate, I posted pics of my 360 which should be similar.(in the 1-800 video section, even though its not video ;D )
 
Might be worth mentioning that I unplugged my regulator at it would flash up to 17,18 etc briefly but holding a slow climbing rev it would stay in the twelves.
 
Also battery freshly charged was 13.20v, now down to 12.78v.
Is that normal?
What should the battery voltage be at normally once ridden.
 
Well did some more research and looks like it's about right now, I know these charging systems are not like new modern technology so looks like as long as it doesn't let the battery completely drain it's about right. And light on is somewhat better for the system.
Still planning on doing the mod for full power as advised with the newer reg/rect though, so il keep riding over the next few days and see what happens. Il probably wire in quick connects for a batt maintainers too for when I don't ride for a few days.
 
If you hardwire for a battery maintainer, make sure you put a timer on it, it's better than permanent connection and cheaper on your power bill (despite the hype by various manufacturers ::) )
As long as battery isn't fully discharged or overcharged, it should last a long time.
Really you should leave a battery sit for 30 minsor so before checking actual charge, the excited electrons show higher voltage directly 'off charger'
 
So I rode today to work 15miles then around town at lunch and about 20miles on the way home because I took the interstate for fun.
I have a battery voltage of 12.12v.
Is that about right? Or to low?
 
Ok so upon connecting my rectifier to the harness would it be directly like this? And just change the plug to snap together?
And regulator in the same spot as stock?

bought the cb450 reg/rectifier today, should arrive in the mail in a few days. hoping for some good results, but if anything atleast it will be upgraded to solid state.
 
Don't need separate regulator with the CB450 one, it has regulator built in (the black wire to switched live)
You can see the little 'slot' in the middle of each connector where tool fits for removal of terminal
 
Whoops shoulda mentioned I was just messing around with a spare old rectifier which is why I asked about the reg. My bad.
Thank you though for the look out.
I will post up the new unit soon.
 
I'm waiting on the same Reg/Rect to put on my 360. I've been checking out the cb400 wiring schematic and to make sure I have this right, the Red wire from the unit goes directly to the batt. (+) and the Black wire from the unit is the sole supply (+)?
So, put my main switch in the Black wire and run coils and lights after the switch? Or maybe I'll still run the coils off of the batt, and put another switch in solely for the ignition circuit. Just thinking out loud now.

I'm not using the stock harness, btw, I built mine from scratch.
 
So, after looking at the diagrams some more, it looks like you want to switch the Red live feed, to the Black (and run everything off of that).

Not meaning to high jack the thread, just working through the same issues.
 
no prob kmoto, the more the merrier, i think our wires are different colors though, i was under the assumption that the rectifier part plugged into my stator, and the regulator part of it into my regulator connections.
 
alright, reg/rect unit came in the mail today, and this is what i plan on doing.

*disconnect the stator block connection.

*eliminate the plug at the harness.

*change the connector at the stator and rectifier so that both can be plugged into each other.

*change connector at regulator and add a connector at regulator wires on bike to plug together.

and thats about it.
does this sound right? im still a bit nervous about getting it right as ive never done it before. lol
 
Yeah, I think yours sounds more complicated then mine, lol, with the connectors and all. I'm interested to see how it works out for you.

Mine should be in too when I get home from work, so I will play with it and hopefully have some useful info to share tomorrow. For me, harness wire colors are meaningless, the new R/R unit pinout is what I'm after. CrazyPJ did a pretty good job of explaining that though.
 
yeah i think pj wrote the colors i am supposed to match up, so il give it a try and see what happens.
 
I didn't catch this one earlier and I may have missed some pertinent point, but let's go back to the beginning of the thread.

13.3-13.5v sounds fine. The older Honda's were wired so that they had a "low" rate of charge with the lights OFF and when headlamps were on, the charge rate increases as it connects in the other two pairs of charge coils.

If you wire those coils in the alternator directly to the new type regulator/rectifier, you will have a greater daytime charge rate.
 
Ok sweet, that's good to know.
My bike has no off switch for the lights so I think it will be good to do the upgrade.
So am I correct in the way of hooking it up?
