Rio & Spectra

To check primary coil resistance, disconnect ignition coil harness connector. Using ohmmeter, check primary resistance between positive (+) and negative (-) terminal of coil or coil pack. Check secondary resistance between coil towers. For resistance check procedure on Rio, see Fig 1. For Spectra resistance check procedure, see Fig 2. Also see IGNITION COIL RESISTANCE  table for resistance specification. If readings are not within specification, replace ignition coil(s).
