SECONDARY SPARK TEST
See Figure 1
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.
- Disconnect a spark plug wire at the spark plug end.
- Connect the wire to the spark tester and ground to a good ground on the engine.
- Crank the engine and check for spark at the tester.
- If spark exists at the tester, the ignition system is functioning properly.
- 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.
- If the rotor is turning, perform the spark test again using the ignition coil wire.
- 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.
