If the bike’s been sitting for while the contacts in the starter button could be dirty or damp. Try flicking the switch through all 3 positions several times. When you put it in “kill” position does it shut down some of the lights? Also, check the magnet in your side stand hasn’t fallen out, although I think T100s and ‘17 onwards should be OK.

Can you hear the fuel pump when the key is switched on? Does the headlight dim when you try to start it? Can you load test the battery? Have you checked the battery connections?

So I finally got my hands on a multimeter to check the battery voltage. Looks like it's just a dead battery. When I disconnect from the battery tender and try to start the bike, it gives a half hearted attempt to crank and then nothing. I'm surprised that the battery on a two year old bike is already dead. It seems fast to me. I went 5 years before changing the battery on my old 07 Speedmaster, never used a battery charger and it always started right up every spring. I'll get a new battery to see if that solves the problem. Are there any good long lasting batteries out there?

How do you know the battery is fully charged? You stated you charged it up last night. That does not mean it will carry a load. Running lights might take 2 amps. To crank the motor, takes a lot more than that. Have you checked to make sure the battery leads are dry and clean. Use a small metal brush used for cleaning battery leads. Any slight oxidation or residue could lead to resistance in the circuit and failure to crank. It ran when you put it away. You took the battery out. If the battery sat in a cold or damp area over the winter, it could have run down to the point it will not hold a charge or has a dead cell. I suggest you take the battery to your local Auto Store and have them run a load test on it. I bet it is the battery or dirty battery leads.

The kill switch is also the starter button, so no longer a potential issue.

Sounds like you found the problem.

I always figure a battery will only last 2 years and anything over that is a bonus. Some last longer than others.

Keep us informed.

I'll have to admit the first spring after I bought my T100 I couldn't start my bike and then remembered you need to pull the clutch lever. A lot of other bikes don't require that and it can be easy to miss if your previous bike was something like a Honda.

There has to be a more economical solution than replacing the battery every year or two. Is there any upgrades available that prolong life?

A good battery tender.
