Diagnosing Blown Fuses
Problems that occur based on temperature can be triggered with a test drive or a heat gun. A spray bottle can be utilized to simulate moisture. If the failure of the fuse is related to movement, a shake down test can be performed by slightly tugging on the wiring harnesses until the circuit breaker or PTC opens.

Tech Feature: Ignition Coil Diagnostics
Import Specialist Gary Goms says there are a variety of opinions about how to test ignition coils and ignition systems. The most basic method is measuring a coil’s primary and secondary resistance.
