Too high, but bike should still run and start.

something's wrong, either with the scale on the multi-meter or ???

perfect!

Too low. Battery is not fully charged or cannot hold the charge (no load capacity).

Battery should read about 12.8-13.2 volts when fully charged......

 

thanks , that was my lawnmower batt. so i should buy one specifically for the bike. the bike only has 10,000 miles but i would like to see if i can get it to run before i put to much money in it.
