Battery check - DC V - 20.
Cool.
srinath.

Copied from a post by Old Feller:

Put your volt-ohm meter into 20 volt range DC setting.

Stick the proper leads on the proper terminals on the battery (you can get into do this just by taking the seat off, the square cut outs are big enough).

Note the resting voltage of the battery as it sits before being started.  Write it down.  12.0 to 12.6 is a common resting range.

Crank the bike and get it to a good fast idle (at or over 1,000 rpm) check the battery voltage again with the engine running.

If resting voltage is over 12 volts and the running voltage is just over 13 volts you have a charging system that is working, but the regulator rectifier is getting marginal and old.   This bike may have issues with the battery not getting charged enough with short trips.

Running voltage at 13.5 to 14.5 is pretty sweet, your regulator rectifier isn't getting old and tired yet.  Your bike should recharge itself on short trips.

Over 15 volts, regulator rectifier is sick and is over charging your battery.


Stators rarely ever go bad, regulator rectifiers crap out much more often.  This test isn't hard to do and a Stealership will charge you $65 to $100 to perform it since you were silly enough to carry it to them to do it for you.  

They like your money in their wallet .....  that's why we call them Stealerships.

They can test your stator separately, both for resistance and for output voltage -- but get this ....

If the battery voltage on a running bike is in the right range, the stator and the regulator rectifier must be operating correctly for it to be there.

The bike dies while in 5th that's the confusing part

Fast idel is 13.35.  Resting is 12.3.  And I adjusted the idol a little cause it died like it was idling too low.  It runs fine now but I'm nervous to drive it back cause if it does it again then ill really be stranded  lol

can you try bumping your idle up a bit?  mine will die if the idle is set too low and i squeeze the clutch to change gear, etc.  pretty much anytime i let off the throttle.

The engine runs but after a min or two it just dies.  I have the fuel filter off as well

I've had something similar happen. It was the connection under the seat. Basically what was happening was that the bike was running off the battery and the charge circuit was barely touching/touching intermittently. It would start up and run for a couple blocks and then die as soon as I threw on a signal light or let the throttle drop. Check those connections under your seat.
