In this video I show you haw to use a ohm meter to test the ignition switch in a Honda GC 190. The ignition switch is a simple on/off switch that connects to the ignition coil and engine ground. When the ignition switch is in the ON position the switch is open and does not allow current to flow through the switch. When the ignition switch is in the OFF position the switch is closed and allows current to flow from the ignition system through the ignition switch, than to ground. This grounds out the ignition system and prevents spark at the spark plug, thus shutting down the engine.
An ohm meter is used to test the ignition switch for continuity. When the switch is open, than no current can flow through the switch and the ohm meter will read infinity, which means infinite resistance. When the switch is closed or in the OFF position current will flow through the switch. The amount of resistance created by the switch in the OFF position should be insignificant, so the meter should show zero resistance. If you do get some resistance when measuring the ignition switch in the OFF position, than check the connections for your meter leads and the ground for the ignition switch, or the contacts within the switch can cause a high resistance reading. If the contacts in the switch are bad, than replace the switch.
Thanks for watching!
