> 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.

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

Today's Featured Article - On the Road with Dave Gohl: Auction Musings - by Dave Gohl. I was thinking the other day about all the auctions I've been to in the last few years. There've been many. Some have been very good, some have been well, disappointing to say the least. But no matter how good or bad auctions may be, we always seem to stay until the item we've come for or are interested in is on the block. I've been to some auctions near and far. I think the furthest has been the Two Cylinder 7 in the Amana Colonies last year. Lots of stuff, lots of people. I've also atten
