PeterWell, that was fun!
I just tried to blow my pinky finger off.
Swapping out some 12V starter batteries in the motorhome—they may be the cause of our problems— and shorted a negative connection I lost track of and positive with a spanner and my wedding ring.
Blew a hole in the ring and took off a couple of layers of skin under it. Had to cut it off, after cooling it under running water for a while. Got a bit hot. A couple of hundred amps will do that.
Still got a finger so, bonus?
Stupid thing is, I *KNOW* to take off my wedding ring when working around electricity, even 12V stuff. Just tired, I guess.
And yeah, the old starter batteries (we have 2, at 900 amps each) were beginning to die, and our mechanic reckons that can cause the issues we have been having with the engine.
We'll see.
Now I have to get a new wedding ring.
