Review on Lisle 19380 Spark Tester by Christopher Theriault

Great help in figuring out what's wrong with my 93 Buick LeSabre, found that the cylinder #6 cable isn't working. So I replaced the spark plug and the spark plug wire still wouldn't fire so I changed the ignition coil and it WORKS. I thought it was fuel injection, but the way it worked (chuffed) missed it a bit. The spool was very easy to change (2 screws), #3 on the spool worked but #6 on the same spool didn't. The other 2 coils (3 total) were fine. Very easy to use, took off a star because I dropped it and the bulb went out and there isn't a replacement that I know of so I'll have to buy another.
