ok thanks for the info you could be right cos there is no sign of it in the parts list but there isn't one for the exhaust sticker on the swing arm neither so maybe thats not suppose to be on the k0

yes think ur right about the meter with being in engineering the tools i have acquired over the years have tended to be more industrial the test meter for example.i have got a little cheap one lying around somewhere.

thanks for that basically the same as i have tried with no reading  maybe with the bike being 40 yrs old its wired slightly different to the modern ones i have tested.on the wiring diagram of the rectifier it looks like the voltage shouldn't go past the diode one way but aloud to go back up the red wire to the battery to charge it.

hi this is the meter i am using as you can see the ammeter part only reads ac i think so hae to go off the volts.did try it but no reading.with the positive connected to the battery on the bike though the red and white connects straight to the rectifier permanently. so the test i did with the leisure battery shows the 12v is coming from the green wire on the rectifier just dont know if it normal.

hi disconnected rectifier and connected a wire from my liesure battery to the red wire of the rectifier and connected my meter to the green [earth] wire of the rectifier and to the negative of the battery and getting 12v is this normal.yet when i test for infinity or continuity between the red and green wire with no power to rectifier no reading.

thanks for the reply but with the ignition off and my meter between the earth of the bike and battery earth i'm getting 12v am i right in thinking something is giving the ground side a 12v supply which it shouldnt.it was an auto electrician who told me this a few years ago. could be doing it wrong but funnily enough about 12 months ago our fork lift truck kept draining the battery over a couple of days i did the same test on it sure enough got a 10v reading across the disconnected earth.the flt guy couldnt find the fault we ended up putting a kill switch from the battery cured the problem sos for goin on a bit.

sos for the grammar.yes i have the negative disconnected ignition off and meter between negative on the battery and earth strap to me it should read 0 volts. i did this test a few years back on my 750 supermagna cos everytime i come to the bike the battery was flat .i found i was gettin about 5 volts reading on the meter finally traced it to the starter solenoid it was shorting inside it.

hi all on my 1970 cb750 just bought new battery before connecting it checked to see if i was getting a drain connected positive terminal and put meter between earth on battery and earth lead off the bike not connected got 12v its a new wiring loom disconnected rectifier no volts so took the sleeving off the wires of rectifier must of got hot in the past and melted so seperated the wires connected it back up getting 12v again am i right in thinkin the rectifier is shortening between the red and green through the rectifier or travelling straight thru the diodes in it
any help would be appreciated
thanks
