There is no charge going into the battery, can I fix this or is it too complicated. I put avolt meter on the battery and reved up the engine but the voltage does not increase, the voltage dropes at the rate of .5 of a volt every 3 minutes.

 

I forgot to mention I have replaced the rectifier.

 

time to check the alternator wiring, You can check it at the connection on the rectifier

 

I have a Haynes repair manual so I will check the system according to their instructions. can someone tell why the bike still runs if I keep the revs high enough when the batter is flat ?

I have the same problem.
Went for a 200km ride yesterday and brokedown 20-metres from the end point
The wiring near the rectifier looks l-i-k-e crap, will have to replace all the connectors
I am also going to make a circuit that warns me of low voltage.

 

When are they going to fix the bloody posting, you have to play, find the hidden SQLphase words to get the post to work

 

markr, the connector on my rectifier was all burned, the bike shop wiered in a second had rectifier but that has not fix my problem.

 

Second r/r may also be fried.
Check charge rate above 3000RPM
Maybe stator is also u/s
