It is time for the new puzzler. This puzzler is automotive in nature. 

Here we go.

This involves one of our mechanics, Crusty. We talk about him a lot. 

A long time ago Crusty is at the end of his workday, and he's over in the parking lot with his truck. He had a '55 Chevy. And he's trying to pry off the pulley for the generator.

And I said to him, "What are you doing?" 

He says, "I'm sick and tired of having a dead battery all the time. This generator doesn't turn fast enough, and as a result, it doesn't charge the battery at low speed, which is all I do. I drive around town. I've got the headlights on, the radio, the heated seat, CD player. Generator doesn't produce enough electricity. The battery gets weaker and weaker, until one morning I come out and the battery is dead. It happens every couple of weeks in the winter and I'm sick of it. So I'm gonna replace it with a pulley that's half the size, so that when this thing isn't running at idle speed or around town, it will charge my battery. What do you think?"

So I say, "Go for it." You know, it isn't my truck. And I wanna see what happens. 

So, he does it. 

Then, about a week later, he is forced to take a little trip on the highway. He has to visit his mother. So, he gets on the highway. 

On the way back, something happens that he and I should have been able to predict as a consequence of this new pulley he installed. 

And that is today's puzzler. What happened to Crusty and his truck on the way back as a consequence of the new pully in his generator. 

Good luck.
