Okay.
Bike is a 81 special. I know just enough about electrical to get myself in trouble. Bike has 1,500 miles on it total so no electronics should be worn out. I preface with, I have done fair amount to forum searches and read through many pages of info, tried to duplicate their tests. Still cannot find problem.
New battery in bike and it was charging at ~14-14.5v while running with rpms up
About a week later and about 50-100miles ridden It now shows 12.00 at idle and 12.2-12.5 when its at 3000+RPM. SO its charging... but not really.
What I have done to check.
1) removed battery and charged overnight to full (same results
2) checked ohm readings on slip rings - all zero out. good.
3) cleaned brushes
4) put in a spare regulator/rectifier i had (same results)
5) cleaned the terminals on reg/rec plugs. (all others looked good)
6) threw hands in air and wrote this thread.
Questions - - is it possible for a new battery to read correctly on week and then limit charging v the next? Is it the battery? (please be this easy).
Any other ideas what would cause a 'low charge' condition with parts that are working one week, not the next and all are very 'new' (low miles).
