I have a standing offer that anyone who is tired of the claims that these things (regs) are oh-so-difficult is welcome to come by and have a beer - and I'll strip both a first and second on the kitchen table in front of 'em, along with showing 'em exactly where you get everything except seats - the only parts that need to be "official".
Knowledge is power. And your reg is no more difficult to work on than your kitchen faucet. Yes, it does require a couple of special tools, but they're not expensive, and are sold to anyone with money.
For those who say "its life support gear!" I say "Yep. And this morning I replaced the ignitor on my furnace, which had failed. $150 to have the furnace man come out? C'mon. The ignitor cost $25 and took 5 mintues to install. Yeah, its a gas furnace - if I do it wrong, I blow up. I'm still here. Next question please?"
I'm not - and never have - said that there are
no good shops. There clearly are. But they are in the severe minority. The only defense to this, as with any other area of knowledge where your life and health are on the line, is to become educated.
You speak to people fixing cars and such. Good analogy, by the way. Have you ever seen one of these "classes" that only lasted an hour or two? Yet this is what makes someone "certified" to repair regs. Oh, that and working for an "authorized" dive shop.
Yes, your brain is really emptied (according to the manufacturers) if you quit or are fired, and no longer work for that authorized dealer.
Tell that one to the independant auto mechanics.
What am I doing about it? What makes sense. Hopefully, beginning with provoking people into thinking. Demonstrating, when someone cares to see it with their own eyes. Living what I believe.
That's more than most will do, and, over time, is more than enough.
