Fig. Fig. 1: The spark tester resembles a spark plug without the ground electrode. It has a ground clip attached to the metal body and places the proper load on the ignition system during testing. This helps to identify intermittent or hard to find problems.

Hyundai suggests that this procedure can be performed with a standard spark plug. A far better method is to use a spark tester (available at most automotive parts stores). The spark tester resembles a spark plug without the ground electrode. It has a ground clip attached to the metal body and places the proper load on the ignition system during testing. This helps to identify intermittent or hard to find problems.

  1. Disconnect a spark plug wire at the spark plug end.
  2.  
  3. Connect the wire to the spark tester and ground to a good ground on the engine.
  4.  
  5. Crank the engine and check for spark at the tester.
  6.  
  7. If spark exists at the tester, the ignition system is functioning properly.
  8.  
  9. If spark does not exist at the spark plug wire, remove the distributor cap and ensure the rotor is turning when the engine is cranked.
  10.  
  11. If the rotor is turning, perform the spark test again using the ignition coil wire.
  12.  
  13. If spark does not exist at the ignition coil wire, test the ignition coil, power transistor and related wiring. Repair or replace components as necessary.
