just a quick question, my 78 750 k8 does not charge at idle, the headlight does dull and eventually when the battery dies as does the bike. but rev it over 1200rpm and it charges to 13.1v and stays there throughout rpm range. does this mean my alternator is cooked? i have another one but i dont want to change it out if i dont have to. i have read some people say it is normal some people say it is not. also would having a brighter head light cause this issue? un sure how to test the stator, not sure if any components have failed or if they have, what ones..... HELP!
