Spark diagnostic tool

[Ameer Antar]

this tool isn't really that great anyway. It won't really tell you how much 
power it has. There are adjustable [0-1.5"] that can tell you how much 
voltage is present. You could get a spark even at low voltages, but it 
might not be enough jump the gap at high pressures which are inside an 
engine during ignition. The spark tool is no better than just holding the 
wire above a ground point. W/ a non-adjustable gap, you have no idea what 
the voltage is. It could be 500V or 30kV....
just my opinion...
