After a ride of about 200 miles, I parked my bike overnight. I packed my gear onto the bike the following morning and it would not start. Slight spark, (no lights, neutral lights very dim) but it acted as if the battery were dead. I had friends push me and she started right up, no problems. The night before, my low beam stopped working, but the high was fine and all of the other functions of the bike were normal. I rode the bike for about 5 miles, and shut it off to gas up. I had assumed that would have been enough to charge the battery a bit. Unfortunately, the bike did not start again – this time, no sign of life at all. I had someone push start me again and the bike started right up, no problems. I rode the 200 mile back home, turned off the bike and it was dead as a doornail again. After unpacking the bike, I spent some time looking and feeling around to see if there might be some loose connections or a bad ground. As I flipped the kill switch off and on, I noticed a slight buzzing from under the seat. It was coming from one or the relay plugs to the left front of the battery. The noise was the same that was coming from the flasher relay when I had a short in the rear turn signals. I have checked the battery and it is fully charged. The gauge light come on (barely) if the kill switch is off. If the kill switch is on, the lights go off completely. If the kill switch is off (the ignition is in the on position) the dash lights are on but very dim. The bike will push start only.

Any advice would be appreciated – thanks!

Sorry, should have mentioned that the bike is a 2005 Buell Blast.

How old is the battery? The symptoms you describe are the same as an old battery that no longer can hold enough of a charge to run the gauges and start the bike.

A bad battery can appear to take a full charge... It sounds like an old battery to me (or maybe a bad battery connection, which is effectively the same thing).

Based on my experience, a 2005 Blast is about 6 years overdue for a new battery.
