Hello Fellas
Some of you guys that have seen my posts know that my Pioneer chainsaw collecting is going all right but tearing them down is another thing.I have quite a few tools as mentioned before but could use some more as well.Today while in a local automotive supply and tool shop I noticed 2 little gizmo's that might prove usefull to me.They are made by Thexton.One is a coil-on plug tester and the other is a adjustable ignition tester.They basically look the same but one has a long wire for the alligator clip.They were on sale and made in the USA.Package say's good for small engines as well as automobiles. Now I need to ask how you fellas use them,the directions could be a bit better on the package.
Thanks
Lawrence
That ignition tester looks exactly the same as one on sale right now at KMS Tools down your way, and which I was already planning on ordering over the weekend along with a bleeder/vacuum tester kit for another $40 - I've been needing one of these in the worst way to perform vacuum tests on crank bearings & gaskets etc. Same price too, it appears. Never seen that other gizmo before, sounds handy. More tools are never a bad thing either way. Sound advice given to me which has proved right over and over again. Even if I know I might only ever need a tool a handful of times, I'd still rather buy it than borrow or rent as long as the cost is reasonable.
As far as my limited knowledge of electronics goes I believe that the voltage is the driving force that forces the electricity ( electrons ) through a conductor and across a gap between two conductors, amperage is the force that gets the work done. I would say the tester is for voltage, spark plugs work on high voltage.

Yep, think of voltage like water behind a dam - more water (voltage) behind the dam equals more pressure, allowing a faster flow through a narrower pipe (amperage). I believe most chainsaw ignition coils produce between 12,000 - 20,000 Volts if they're nice and fresh.
A little offtopic, I have a 15kV Neon sign transformer that'll
start an arc at 3/4" gap, and can be drawn out to over 3" arc before it fails. It only puts out about 40 mA though, which is about what a cell phone might use on standby. It's neat to play with, but I'm building a high-frequency arc stabilizer for my welder out of it so I can run a TIG torch. It was just a cheapo Lincoln AC buzzbox, but I already put the guts in a bigger metal enclosure and added a rectifier stack to give DC output (which works beautifully BTW compared to the old AC), so it should be a half-decent machine by the time I'm done modding it. My mom is always worrying I'm going to burn down the house or kill myself with it though.
