There are several checks, unique to the electronic ignition system, which can be made to locate or repair trouble. The gap between the pole piece and pickup coil can be checked and adjusted, and the electrical resistance of the pickup coil can be checked on most vehicles built through 1982. Although it can be checked, the gap is non-adjustable on the RX-7. The resistance of the ignition coil(s) can be checked on all electronic ignition equipped vehicles.
