I am testing correctly.
I was basically trying to ask what things whould I check if its on drawing off the main 50 amp fuse.

My apologies you said if you hooked up a volt meter the way you were saying it would read 12 volts.

As far as amps, you shouldn't have much of a draw at all except any "keep alive" type modules that would be on the bike. I am not sure if the electronic odometer draws or not. In a car, I wouldn't suspect to see more than 1 amp draw, and that may be high.

Most multimeters are 10 amps max, that should be good enough to check, if its higher it will blow the fuse in the multimeter.

Hook it up between the negative battery cable and post...and start pulling fuses till it goes out, or dims as you could have draw on more than one circuit...

Easy peasy
I've done it that way, i agree, in a hurry a test light can be useful. High amps bright,low amps dim etc.

One at a time, unplug, read battery draw, reconnect the following (all fuses installed):

ECM
Voltage Regulator
Stator
ABS Module
Yes 127 not 12.7 I will check them all and everythis else and let you know what I find. I am not using my phone so I am going back and forth from the bike to my computer. Thank You for the help

So I had to replace the VSS, which involved completely removing the battery and starter. When I put everything back together there is presently no excessive draw. Ill take it out for a long ride in the morning and see if the draw comes back after riding it.
