Spark Test

WARNING: This page is about a different car, the 1993 Volkswagen Passat, 1993 Volkswagen Fox, 1993 Volkswagen EuroVan, 1993 Volkswagen Corrado, and 1993 Volkswagen Cabriolet. However, it is still accessible from the selected car via links, so may be relevant.

Using an ohmmeter, check resistance of each spark plug wire. See HIGH TENSION WIRE RESISTANCE table. Check for a strong Blue spark at coil wire and at each spark plug wire by holding wire terminal 5/16" from ground while cranking engine.
Disconnect and inspect all related ignition system connectors and harness. Clean or repair if necessary. If related connectors and harness are okay, remove negative battery cable. Disconnect secondary and primary leads from ignition coil.
Using ohmmeter, check primary resistance between primary terminals of coil. Check secondary resistance between coil secondary terminal and primary positive terminal. Replace coil if readings are not within specifications. See IGNITION COIL RESISTANCE table.
