> Go back and see if I limited the meter one the average person my YT has
I don't think you did. But if you're serious about wanting an accurate multimeter, there are plenty of new and used lab multimeters available on eBay for a few hundred bucks; basically the price of a good new handheld DMM with true RMS capability. Here's one such multimeter: Refurbished Fluke 8840A.
> Using Ohm's law is worthless if you can't measure resistance with any degree of accuracy. It's better to calculate ohm. I think I'll make a simple electronic quiz to show people how to use the cheapie voltmeters and ammeters to calculate the resistance of a coil and ballast.
The problem you're dealing with here is the resistance is not a fixed value. Measuring the resistance of either the coil or resistor with a multimeter will yield a different value than the resistance under full load.
> Just a brain fart. Can I use the meter people use to test the voltage of their electric fences to measure spark plug voltage?
I think the peak voltage of a typical electric fence is far less than the voltage of a typical ignition system. You can buy cheap spark testers at any auto parts store. Here's one: AutoZone spark tester

Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
