Hummer Man,
I don't think you have to be a "professional" to know the difference between + and -. I also find it hard to fault Steve. I think anyone would
ASSUME the polarity to be correct since most morons wouldn't even do something so stupid. He bought it used and at least he hooked up his connections right, although we can once again assume, he never checked it or used it.
I have had "professionals" do far stupider things than that and paid them for their ignorance.
As for me Ill take my chances and do most things myself. I can read and if im not clear I can ask questions. At least if there is a problem later I have a better chance of figuring it out or the trail or the side of the road.
Bottom line, why pay someone to screw up your ride when you can screw it up yourself and cut out the middle man
