      A:

      Great question Neil, I will be happy to help. The answer is yes; just pretend this tester is a spark plug on your vehicle. The fact that your vehicle has long rubber boots will not impede the use of this ignition tester. I hope this helps you find the bad coil on your vehicle and gets you firing on all cylinders again!

      Hi Shadetree! I'm glad to assist. There is not specific gap setting for the ignition tester, the gap will be specific to the particular spark plug that you want to test on your vehicle.

  • Q:

    how does this work

      A:

      With reference to your inquiry on the Autocraft HEI Ignition Tester - part# AC664, the HEI Spark Tester helps in the diagnosis of the Ignition System by stress testing the Ignition Coil and any other component between it and the Spark Plug (like: a Distributor Cap, Distributor Rotor, Ignition Cables, etc). The tester looks like a Spark Plug with some very big and obvious differences. The biggest one is that there's no ground electrode hovering over the center electrode. Instead, there's a huge air gap between its center electrode and its body. When you connect the Spark Tester to the Spark Plug Cable or the Ignition Coil Boot (for Coil-on-Plug Systems) and crank the engine, the HEI Spark Tester forces the Ignition Coil to produce its maximum output so the spark can jump across the very large air gap. This action stress-tests the Ignition Coil. The voltage necessary to fire the HEI Spark Tester is around 35,000 volts. This kind of voltage produces a very bright and bluish spark that's also audible. This method of testing for spark is the best one and does not cause any damage to the components. If the Ignition Coil or whatever component that is in between it and the Tester are on their last leg, you'll get a NO-SPARK result on the tester.
