Is this factory 1975 stuff

Just an FYI.... it takes well under 1 amp to kill......but 12V can't push any appreciable current through any part of you. The lowest voltage documented to kill is something like 42V an only in special conditions. So don't sweat that too much.

Some of the responses are not ideal.... but expecting free help to behave in a certain way is not realistic. If it was paid for, that would be a different kettle of fish.
You're 100% correct. Sometimes peoples responses may be as simple as, " Maybe this " Which might lead you on a path to research that idea. It can be hit, and miss. Ie: There was a guy up here who just posted a question. He wanted to know why his charging system was over charging his battery ? He was on his 2nd battery with no idea. There were 10 different answers up there. Now he had 10 possible leads, that he could investigate. And that beats the hell out of having no clue. But of course you had to have the one guy who's only 2 cents was : "I couldn't tell you unless the car was in front of me." Why would someone ever bother putting in the effort to type that ?
On the electrical side of things, this is interesting stuff. Humans can feel one-one thousandth of an amp, or one milliamp, of electricity. To put that in perspective, it takes about 800 milliamps to light a 100-watt light bulb. Ten milliamps can cause a person pain, and at 14 to 15 milliamps, you will lose muscle control, an experience called the “cannot let go” phenomenon. Fifty milliamps is generally where you run the risk of dying from an abnormal heart rhythm. But during an ECT session patients generally receive a shock of up to 100 thousand volts. There's a whole other side of this question with electrical frequency that I don't really comprehend, so I won't even try. Shocking.
