Never thought of it before. I just use the "one way it locks up, the
other way it doesn't" method. You have the clutch cover off ?
Reg / rectifier ? There is a chart for checking one in the OEM manual
but it is about useless. You can check from yellow to yellow to yellow and
black to white and all to ground if that's your only option now. I prefer to do
it running. I just check the output with a n ammeter. Very easy to determine
how well it works. Tell me what you want to do and I try to walk you through.
Best if you can get an ammeter that has a range of 10A and reads both ways. Try
to borrow one. That's the best check (IMHO)

Hey Dennis thanks again for your advise,I think you were also the
one who sent me a message on where to find decals you are a great service to
the nighthawk lovers,I wish you were here. I have not had a chance to get back
after it yet, shooting for thanksgiving holidays...Its been running,oil is
correct shouldn't be any rust.I pulled the starter and held it to the engine
for a ground, the starter spins the crankshaft does not. I had started it just
before the the prob. showed up, it died I pushed the starter button again and
it just spun. I have been restoring this bike for the last 2 years and was just
about to get it legal, I am not going to give up on this bike it only has 3200
miles on it,it sat covered in a home garage for 20 years I bought it 11/07 the
owner before me put les than 20 miles on it (thats a story for a later day) I
have been riding it around my nieborhood and have put around 50 miles on it. I
will try your suggestions and get back to you again thanks for your advise. I
live in Dallas so I have many good days to work on it and some day ride it
again...There is a sweet looking 84 700 nighthawk on ebay for 1200.right I'm
tempted but I believe mine is better...

I can't answer your question any more than that. Try to
answer mine. If it worked recently, why not now ? It only takes a small effort
to engage the starter clutch, even an almost dead battery will engage it. To
have one that does not, is more than rare. If I wrote a list of the top one
hundred things that go wrong with one of those, the starter clutch wouldn't be
on it. Maybe now you can see that it's either a catastrophic problem or
something stupid. Let's find out which one it is.
I will repeat to you what I think you said first. Your
starter motor works (spins, makes nice whirring noise) but the engine
(crankshaft) does not turn ? OR; is it that it does not start ?
If you think I'm being smart with you, try to get a grasp
on this... "it won't go" What's that mean ? The customer knows but he can't
tell you, he already did "it won't go" Like in the chain broke ? It won't start
? It stalls ? He knocked out the transmission ? I have to listen to this every
day. When I understand what is wrong, we proceed. More than one person on this
site has given a failure description that got a wrong answer. A clear
understanding of a problem gets an answer. I'm not going to take the blame for
somebody going through hell and back because I got it wrong. I have to
interpret a customer's complaint so that a tech can do his job in an efficient
manner. My techs depend on me to get them off to a good start on every job. I'd
like to do the same for people here.

Even after years at my dealers, I've yet to have
to repair / replace a starter clutch on a 550/650/700 SC. Your description is
of one that failed. They are located deep within... Remove engine, disassemble,
etc. Now let's slow down a bit. Since they are almost indestructible, what
happened to yours ? The most often repaired ones are in VT Hondas. They can
crack open and fail. A CB-SC is not likely to do this. Has this bike been in
use as of late ? What weight oil is in it ? Heavy oil can stop them from
working. Was it allowed to sit for an extended time without oil in it ? If it
rusted, then the rollers are frozen in place.
Lastly, do you have a repair manual ? Get
familiar with how the starter clutch works. It is a one-way roller device.
Turning it backwards, it will not engage. Does the starter motor run in reverse
? >>> see below<<<
One last freaky item since I would hate to see
somebody go through a ton of hard work to find something stupid. Did you
recharge the battery or replace it recently ? A battery can be charged in
reverse (yes it can ! From a completely dead condition) This would cause damage
to the regulator / rectifier and cause the starter to turn backwards. The
starter clutch will not work in reverse. I'm not there to see this and have to
take your word that this is this and that is that. In a serious matter like
this, be careful, be complete. If you really have a starter clutch issue be
prepared for a long winter of work. Eliminate any possibility of anything else.
