Welcome to the forum!
With all being new, it's probably something simple. My first impression is that you've probably lost a good ground from taking it out and playing on it. The vibration will loosen up your cables. First, check both your connections on your battery to make sure they are nice and clean, tight too!....then, look where your ground wire goes to your block. I think it hooks up to the side of your starter. Make sure this is clean and tight also.
Last, if all these wires are tight, then you'll need to open your electrical box and look at the red wire coming in from your battery. It's connected to the solenoid. Check to see that both wires going to and leaving the solenoid are also tight. Then, try to start it again. Leave the electrical box cover off. Then try to start it again. If the solenoid is bad, you'll notice, that where the click is coming from. That part will have to be replaced. There not that expensive. But before you replace it, make sure you disconnect your battery wires..................:cheers:
