Topic: My R/R Outputs too much voltage

[uptworedline]

I wired in a yamaha voltage regulator/rectifier on my bike, but this R/R has 7 wires compared to my original 5. The voltage at the battery at 2500rpm is 18.1V compared to the correct value of ~14.5 which it should be.

my entire circuit is flawless, i have everything grounded perfectly and soldered all the connections. there were a total of 7 wires coming off the zx6r R/R (see attached picture). I labeled where on the schematic each of the wires go except for the left 3 which come from the magneto.

currently, i use the BK/BL for the (+) wire and the BK/W for the Ground (-) wire and the two others (BK/R and BK) are not used at all. i'm sensing this is where my problem is, i think the voltage is too high because the R/R thinks the high beam is on etc?

any electrical gurus?

Well. What bike?
You have posted about a CB1000C before. If you are using a Ninja R/R on a CB100C...
This engine has an excited field alternator with brushes carrying power to the field coils in the rotor, essentially the same as the CB650 type.
Problem one: the drawing you show has no provision for a field coil connection. the Ninja has a permanent magnet alternator, the kawi rectifier/regulator converts this to DC and controls the output voltage (I don't know how, there are a bunch of possibilities).
Problem two: If the field is not connected (seeing as there's no wires on the regulator for it...) then you would get ZERO output power whereas you seem to have too much.
Problem three: Kawasaki wire colors are totally different from Honda. Kawasaki uses grey and brown for switched (ignition) power, black/yellow for ground, white for battery plus (unfused). I have no clue as to why the regulator might want to know that the headlight is on, or possibly it supplies AC power to the headlight???
Anyway, possibly this might work but you may overheat the alternator field coil as you have to connect it to ignition power (and presumably already have).
The wiring to a typical Honda would be the three Kaw alternator wires (blacks) to the three Honda yellows. Kaw BK/BL to Honda red. Kaw BK/R to Honda black. The BK headlight relay one, I dunno... not knowing if it supplies headlight power or senses the headlight is on, I would leave it not connected and see what happens.
I would strongly recommend just using the proper reg/rect for your bike though.
If you actually have the Ninja and the system is acting up, be super careful. Overvoltage may damage the engine control computer. Get another reg/rect and try it: this unit is the prime suspect in an overvoltage situation.

I'm sorry I should have been more specific, but you explained pretty well. the bike it's on is a 996 superhawk. i blew the main fuse so i won't make any progress until i pick another one up...put i'll post back, thanks for your help so far man.

ok bump for who ever can still help me out

i tested all 3 wires not touching anything.

1 (BL/BK) had about 12.1 at idle would go down to 10 on really low idle, and 17.5 @2500rpm.

2 (BR) was .14V
3 (BK) was .02V.

now i hooked them up to the hawk system i put the .14V and 18V together and it blew the main fuse, no biggie.
i put the 18V and the .02V together and the battery would charge at ~.75V which is weird.
all 3 at the same time give me .35V
i put the 2 lower V ones (.02 and .14) together they gave me .3V and the BK/BL gives me it's same 17V+ when those others are hooked together


any thoughts?

This has got to be the most confusing, least articulate series of questions and answers I've seen in a long time.   


Hmmm....  you have a Honda 996 superhawk (a modern superbike) and you wired up a 'Yamaha' voltage regulator from a Kawasaki ZX6R.  One has 7 wires, one has 5.    Someone makes some suggestions relative to a vintage CB1000C, which may or may not be the same kind of system at all.  Then, you just seem to randomly connect various wires together and blow fuses.  And you bump the thread and you want thoughts or suggestions??


Get a Honda 996 Superhawk R/R and hook it up per the Honda 996 Superhawk wiring diagram.



And, does that wiring diagram REALLY say 'Regurator'?  Sounds like a bad spoof of a Japanese movie...

^ha yep i saw the regurator too.... but honda cb1000 is my dads asked a q long time back. and the reason i switched R/R's is because the honda SH ones are JUNK. they fail on people all the time and are not designed well that's why people switch for yamaha and kaw ones all the time.

Don't the Superhawk forums discuss this?

I know that the VFR750/800 also have real R/R probs (much discussed on all VFR sites) and there are several options available (even the Honda dealers stock some of them!)

i just bought another r/r thanks for all the help
