Had to work late last night, and didn't get a chance to try jumping straight to the starter.
OlHoss, I don't even touch the starter button. As soon as I hook the battery up, I can hear the buzzing sound. If I don't have to work late again tonight, I'll pay closer attention to where the sound is coming from, and try jumping straight to the starter terminal.
Something is definitely not right if the buzzing occurs w/o touching the start button.
This is a long shot, but quick and easy to do, so try these--
Try turning the key on and off a few times.
Flick the engine run/kill switch a few times. (Cleans any corrosion off contacts)
Tap the start button housing ( and the electrical "puck" on the bottom of the ignition switch) with a screwdriver handle or blade. Maybe the contacts are partially sticking together.
Check that the clutch and side stand safety switches are moving freely, and the neutral light is on.
What is your battery voltage after charging it?
Is the battery electrolyte level between the low and full lines?
Have the vendor do a load test on your "new" battery.
Ask if you can pay the difference and trade up to a MF-AGM battery.
