How to tell if my ignition switch has faulty wiring?

Electrical and wiring issues affecting the ignition switch wiring can lead to short circuit thus making it impossible to touch with your hands. You can easily troubleshoot the faulty wiring of ignition switch by connecting a test light device to the ignition switch’s ignition terminal that is turned on. If the device lights up, it indicates that the ignition switch delivers power to the starter. On the other hand, if both the checks display positive, there may be some wiring problems either between the starter and ignition switch or the ignition switch and battery.
