charging issues

hi all

  as the title suggests,the CB500 has charging issues,

at about  4,000rpm it produces a low charge,if I put the lights on,there is no increase,

I have checked the 3 yellow wires,all link to each other,

some time ago I fitted  a RR24 combined regulator/rectifier,

 could that have gone??

any ideas of what to test for?

thanks

Bryanj:
Yes to first question but not necessarily.
There is a full charging system diagnostic system test in the Honda manual

Johnwebley:
OK

  I will check it out,

   

Johnwebley:
the rectifier/regulator  is an RR24,fitted about 10years ago,

  after playing with a multi meter ,the stator and rotor have continuity,

 on to Electex world web site,found a helpful page,on it is how to test the reg,

  my figures are not as specified,

ordered another ,my haven't prices  gone up!!!!

Bryanj:
Make sure all your earth connections are clean and tight plus all the multiblock connectors or you may fry your new part
