"Cool photo. Is that your grandpa or something?" Mark pointed to the sun-bleached black and white photo that hung on the wall of the garage. A smiling, grease-stained man in mechanic's overalls stood proudly in front of a 1950s dirt-track racer. Sitting at his feet was a trophy.
Danny nodded. "Yup, that's him. He's my inspiration. He used to talk about building motors and fixing up cars underneath the old shade tree. You can see it there in the background." Mark kept staring at the photo. Satisfaction, thought Mark. That was the only word that he could use to describe it. The pure, unbridled joy of winning a competition, based not only on one's skill with a steering wheel and clutch, but with a screwdriver and a hammer too. Mark knew that feeling well; he loved winning as much as anybody and he built his own machines too.
This time, however, he needed some help. Danny was the best shade-tree mechanic in the city, and a good friend to boot. Mark knew Danny would be able to fix the reliability problems plaguing his machine, issues that he couldn't seem to trace. He needed Danny's skill in order to be ready for the weekend.
"Let's take a look at what you brought me." Mark gladly obliged. The candy-apple-red paint glimmered in the garage as Danny let out a low whistle.
"That's one hell of a machine you've got there." Mark's pride swelled.
"Yeah, I did the whole finish myself. Two coats of primer, then three color coats, then gloss, then wet sanding, then I hit it with gloss again. Waxed it just to be safe." Danny admired his reflection in the shine of the surface.
"If it looks so good, then what's the problem?"
"I think it has a short, or a bad battery, or something. At high speeds it starts blowing fuses and just dies."
"Well, that could be a lot of things. Let's take a look." They gently lifted the hood off and set it aside, careful not to scratch the finish. Danny scanned the chassis code. Using his wealth of knowledge about serial numbers and build orders, he noticed something right away.
"Aha!"
"What is it?"
"See that code there? It's a 24X97F. You have an early build."
"Alright, so what?"
"They made a running change late in the year. They redesigned part of the voltage regulator so that the fuse wouldn't blow when the system was running at max charge. The new part is a lot more reliable." Mark nodded his head in understanding, but he was worried.
"Can we get it fixed in time? The tournament is this weekend!"
"Calm down, it's an easy fix. I think I've got the part. We have to do a little soldering, but it's no big deal."
"Ah, great." Before long, they'd yanked out the subassembly and had it in pieces on Danny's workbench. After a good thirty minutes of rifling through various disheveled bins, they finally found the replacement part.
"Got it." Danny held up the small clear baggie triumphantly. It was a thin piece of metal, barely an inch long.
"That's it?" Mark was skeptical.
"Hey, I know what I'm talking about, alright? You stick to paint." He was already plugging in the soldering iron. A couple dabs later, and the new part was secure. Danny proffered the bad bit to Mark.
"You see how burnt it looks in the middle? That's because they cheaped out on the design. Stupid bean counters, they wound up fixing it anyway. Grandpa used to complain about them too."
"Huh. Well, let's get it put back together so I can check your work." Thus began the laborious process of reassembly. After many more admonishments to not scratch the paint, Danny had successfully put the whole thing back together. A new fuse, and it was ready to fire up.
"Okay, let's give it a whirl." Mark's machine turned over instantly, whirring lustily in the garage. Danny sat his biggest box fan in front of it, and they ran it flat out for a few minutes. It was solid as a rock. A few more checks, and Mark was satisfied. He was ready to stomp the competition yet again.
"Couldn't have done it without you."
"No problem, man. Good luck with Battlefield 4 this weekend." They admired the freshly-repaired computer, glinting there on its stand. Danny looked back up at the photo of Grandpa on the wall. Sure, it wasn't a car, but he figured the old man would have approved. He always admired mechanical skill of any type. They carried the machine outside and gently sat it in Mark's car. The color of his lowered Prelude matched that of his computer.
"Now that it's getting warm again, are you going to sign up for any more SCCA stuff?"
"Yeah, but I need to reset the suspension first."
"Well, we can work on that next weekend."
