not sure how to answer the first part of the question. I pumped the pedal, turned the key, and you hear and feel a loud clunk. Try it a second later and it starts. It runs and drives fine for the rest of the day. I will look into the wires and the bolts tomorrow morning when it's cooler. I had the starter off to clean it months ago, maybe it wasn't bolted up tight enough, I hope it's something simple like that. I was checking to see if there were any signs of a starter going bad. It's only done it after it has sat for the night.
