I need help guys...

hi Guys, I've had the reg/rec checked out and its ok, the mechanic is going to check what the generator is
kicking out, what should the spec be for the generator ? any ideas as to what the problem maybe ?

This is all the manual says.. Basically, if you have continuity, it should be good...

I question whether this "mechanic" knows what he is doing. If you are still getting 18-19V, the regulator is no good -- period.

The generator is either working or not working the regulator controls the voltage so I am with Lawrence I don't think your mechanic knows what he is talking about.

if i remember correctly from the repair manual you should read between 14 to 14.5 on your meter for it to be in range.

That voltage would be the output of the Regulator NOT the stator.. The stator puts out AC voltage..
I attached pictures of the pages from the manual.. It only mentions continuity testing, not voltage testing..

If you are getting 18+ volts, it seems like all three phases of the stator are likely working to get that much voltage..

thanks i will check my clutch again, but it looks like its where it needs to be but i will recheck it.

update.... i took the bike back to my bike shop, changed reg/rec and still got the same problem..
everything is fine for the first few seconds of firing her up then it starts over charging at 2000+ rpm..
any ideas ???? the only other thing i changed was the magneto casing gasket and things seemed ok in there... Any ideas please ???? could it be something else ???? i've just noticed a silicone rectifier with 3 spade connectors, could it be that ?

Check the smaller black wire going to the RR.

The alternator and RR are designed to be able to put out a higher voltage than needed. It is the job of the black wire to turn the regulator output on when the battery voltage is low and turn it off when the voltage gets high. This happens quickly, six times for every alternator rotation. if the black wire is miss connected, open, or shorted the RR will think the voltage is zero and it will keep trying make the voltage higher. The voltage on the black wire, measured at the RR, should be the same as the battery voltage; anything different is wrong.

PS. If that fixes the problem, give thanks to Harold Stephen Black.

hi, on the regulator unit i have 3 yellow wires, 2 red/white and 2 green wires.. i also have a black wire that comes out of the unit but i can't see where it goes to..?? in the previous paragraph a black wire is mentioned, i cant see where my black wirecouples to.. help please...

You may get some help from the schematic.

I made a bad assumption that your RR would be wired like my 83. Terry's 96 manual does not show any black wire; I wonder where yours goes. It could be that the original Honda RR used an internal connection to red/white instead a black.

But the regulator you have now does have a black and it is connected somewhere. If the RR is not OEM, maybe the black wire was added sometime in the bike's history to make it work. Do you have any documentation for the replacement RR?

I'm not going to be much help since I really don't know the 96. It sounds to me like either the regulator is broken and unable to reduce the alternator output voltage (not likely since you tried a different one), or that it works but thinks the voltage is too low.

It has been mentioned before, but never blindly trust your test equipment. It could be the mechanic sees the regulator as good and you see it as bad because of inaccuracy in your meter. Measure a different, good battery like in a car. With the engine off a fully charged battery is around 13 volts just after it is charged and about 12.5 after resting an hour or so. Your measurement should differ by no more than 1 volt. The voltages you mention have been measured at the posts of the battery haven't they?

hi,
update... i still haven't had the bike back to my garage yet due to the weather, but today i had another look around the bike and started it up... i noticed that the gauge was showing over charging after about 15 seconds of revs......and that the 3 yellow wires from the stator to the connection block were very hot..the 3 yellow wires from the reg / rec to the connection block were ok.. any ideas???

punchy · March 24, 2015, 01:19:13 PM

come on guys, over a 1000 views and no replys ....

This sounds really weird, punchy. Where are you located?
