Freddie had already installed a master cutoff switch that did everything BUT kill the motor.... so, in the interest of expediency, I am going to use the relay I just bought, to defeat (interrupt) the primary ignition circuit to kill the motor when the switch is turned off.
I don't see any reason why that won't work; do you?
Thanks for the info! Somebody needs to tell the guy who wrote that bevy of articles you sent the URL for, that a pulley is not "reciprocating weight." He refers to it in that manner several times in the text of that dialogue, so I know it wasn't a fluke; he really believes that. It was an unwelcome distraction in an otherwise well-written assemblage of articles. Lots of good information there... and, I don't think that's nit-picking.
