How Do You Check The Ignition Coil Of A 1997 Volkswagen Jetta GL 2.0L 5-Speed?

To check your ignition coil, you need to verify proper resistance across two sets of terminals, and you need to make sure you have no cracks in its housing. Locate the ignition coil.

Remove the coil wire, which is the rubber wire that leads to the center of the distributor cap. Remove the plastic cover that protects the terminals situated between the 3-pin connector and the coil wire connector. Using your ohmmeter or multimeter, check resistance across terminals 1 (the lower terminal) and 15 (the upper terminal), which were revealed when you removed the plastic terminals cover in the previous step. Resistance should fall, inclusively, between 0.5 and 0.7 ohms. Check ...  more
