mo goldie:
are ok guy`s you know from me that your help in always Appreciated in whatever you have said and done.....
we know that help nowadays is hard to come by, I do try and do everything myself,,, but like the charging it gets
a bit of a nightmare for me. but you have both given me hope that there is some good people out there to help.
I have already made up the wiring at both ends from Alternator to the Rectifier Ash......... just need to put them
Carbs back on and do a on the bench set up and then the tank back on as not got a remote petrol bottle then should be good to go.....
so thanks again to you both ;D
and thanks Ash for the needles in advance ...... I don't know but I have got coming just one Vacum spring off a honda CBR400 just to try if that will fit if it do I will try and get anther one.

Hi
just done the job Ash started bike with just the yellow in line and it went to below 11.8 volts.... then put the white on with the yellow and it went to 12.8 Volts revving to about 3.000 so it is there but Not through the wiring harness ..... so something still a miss do you think with either the stator as it don`t read just using the yellow coils as only give out a good voltage when connecting the white for the lighting........ so do you think stator...... if so I Know you said you had two......can I Bye one if you think it is that ?
Cheers Mo
oh the Vacuum Chamber spring I got from the CBR400 works a treat No Binding up and its Not so Heavy that it upsets the Vacuum of the slide so it is Nice and smooth. so ordered anther one......so if anyone else wants them I think he has got about 5 left...hope that help someone else out :)

Mo ... I wonder if it's anything to do with the battery. Those later 5-speed epoxy coated stators are pretty reliable and you said you thought that the stator magnets still have a lot of magnetic strength, so I would imagine you should be generating a decent amount of power/
If your meter has a 10 Amp DC range it may be worth connecting it in series between the battery positive terminal and the wires that connect to the battery as in this Honda diagram attached. IMPORTANT THOUGH !!! Don't use the electric starter ... only use kick-start. Measure the current with just the yellow wire connected from the alternator and then with both yellow and white connected. Report back with your findings at tickover and 3k RPM.
If your meter does have the 10A DC range you need to connect the red probe to the high current socket on the meter. Send me details of your meter and I can suss it out if you are uncertain.
UPDATE ! You meter does indeed have a 10A DC range as I just checked it out in one of the pictures in an earlier posts and there is a 10A red socket to be used in conjunction with the normal black negative socket.

Are thanks Ash
I will give that a try over the next day or so and see..... I have two meters one a fluke and the one you see which is a new one all bells and you Know what ..... which is all automatic so will try both.....it was meant to be a new battery what came with the bike.......... but if it is that at Fault I will get a Motobatt one if it is..as I got them on all my bikes.... My Kh400 had one on that 13 years before I changed it last year, I built that 17 years ago this year .... had to rebuild it two years ago after a silly "woman" ( Girl ) done a U turn in font of me coming back from the Copdock bike show after a good day as my BSA won but coming back home on the KH400 she did that......... But ha ho after a broken Shoulder and 8 broken ribs later I am here to tell the story as they say.
Cheers
Mo

Oh dear glad you recovered OK Mo.
Not saying the battery is at fault just another thing to try as I read on another forum that a guys charging issues were down to the battery in the end ..... after a lot of head scratching.
If you then still suspect the stator then send it to me and I will check it out for you electrically.
