I'm just happy the smoke didn't come out. I can wire a car from scratch, but don't really get electronics. I was happy the other day to run 3 phase power to a new sanding machine and not get a firework show.
When you wire a car correctly from scratch, you show that you have a good 'gut level' grasp of electrical theory. If you are interested in electronics, you can pick up some of the more subtle effects just by measuring carefully. This is a lot easier when you ignore people who insist that electronics is more complicated than the stuff you already know.
With the cars and your sanding machine, you solidly connected the things that should conduct electricity and carefully insulated the things that should not conduct electricity, yes? The rationale behind that process has only been known to humankind for about 230 years. It was a scientific secret, then!
