This must have been heavy on your mind to post that at 1:00am. Helping out on someone's dark boat until late?
I don't know; as a very mechanically inclined person, these simple things baffle me. When it comes so easily, and truly simple concepts that are not exactly cutting edge. I have a regular/preferred customer right now that I gave a sympathy meter too a couple of weeks ago, and i would bet a hundred bucks he hasn't opened up the box at all. I have tried several times to explain the difference between AC & DC voltages to the sum of, "your auto and boat is twelve volts, and the house is 110v". Mostly. And he'll never get it. Very smart individual that is self employed successfully. I wouldn't do his job for a million bucks a year, but he likes it, and I evidently don't need money bad enough. It ain't like he's pushing a hot-dog cart..
My brother-in-law to this day can not change an auto battery. He shoots in the low 60's at golf and is a pro. Very good obviously, and makes enough money to hire people to do these things. With no inclination to learn this at all. In my immediate neighborhood, I'll bet there isn't two guys here that know how to jump start their own auto. While it's fair to say this area doesn't attract your common mechanic, it is still puzzling that these simple skills go utterly disregarded. Sadly these are simple things that don't have an app. Google will not start a dead engine. I had an incident a month ago, a USArmy general no less that powered out offshore. After an hour of trying to describe how to series two twelve volt dying batteries straight to the starter to re establish power, I gave up and told him to call Sea Tow. Damnnnnnn.. How frustrating.
Some people will never learn. They just do not want to. I haven't taken a new customer in over a year and have tried hard to just retire, but people like this keep me busy. Must be some sense of obligation, but now I wonder if I am just enabling them..
I'm ranting as well. Go figure. Mechanics are, or they are not. There certainly seems to be no shortage of business, whether you want it or not..
