Hi guys, I had a dead battery this after noon and at first I assumed I had just left the keys to the on spot which killed it.
But after connecting my trickle charger it practically stated instantly.
Now is where it throws me. I ran it for about 15 miles and and the battery was dead again, the gauges moved but as soon as I turned the crank they dropped. Finally after an hour of the trickle charger not working I used a car battery to get it going. I drove another 20 miles and then home to safety. I used a volt tester and here is what I got.
Bike off= volts 12 -13 volts direct to battery
Bike running = 7 - 8 volts.
also in idle the display volt meter drops when I press brakes.
The headlights burn bright as always when its running and I thought they ran off the generator.
And why would the volts drop when its running.

Time for a new stator.

Might NOT be the stator.. it could and more likely is the rectifier/regulator...
Certainly you are not getting a charge voltage so you need to check the voltages coming off the stator

hmm so I I think it will be easier to check my regulator first.Is there something specific to look for while I'm testing? I mean if volt = less then something then bingo.Or will I need to check them both regardless?

what kind of regulator do you have ? perhaps charge the battery slow and over night . read the battery voltage after fully charged , then let it sit for an hour and read the voltage again , should be over 12.6 if not change the battery .

Here is a stator check for multimeter...if you need it.. Attachments:

Ok so I am a little confused but maybe its good news. While jiggling the charging clamps I noticed it would sometimes and suddenly jump to 12-13 v on the dashboard voltmeter then It would crank right up.
I thought maybe a simple bad connection,the battery was kinda corroded. I removed/cleaned/tightened the batt posts. It seems fine now, it cranks and when I use my tester it shows 12-13 when off and it stays at 13 ish when running.It goes up a volt or so when I rev it.
I did charge it overnight so maybe it just looks good because the battery is charged in that case I guess it will run down again.
I got my fingers crossed.

No, it was a loose connection.. always the simple things! Should be fine...
