By | June 13, 2022



The 1970 Ford F 100 ignition switch is a reliable and important part of the truck’s engine. If it fails, it can lead to engine problems and costly repairs. To ensure that your ignition switch is in good working order, you should perform a bench test. This article will provide step-by-step instructions on how to properly bench test your 1970 Ford F 100 ignition switch.

The first step in testing an ignition switch is to disable the vehicle’s power. This can be done by disconnecting the battery cables or using an appropriate fuse. Then, remove the ignition switch from the truck. Be sure to keep track of the wires connected to the switch and how they were initially routed so that you can re-install them correctly when finished.

Once the switch is disconnected, use a voltmeter or multimeter to check the continuity between the switch terminals. If the reading is zero, then the switch is functioning properly. If the reading is higher than zero, then the switch is faulty and needs to be replaced. You may also want to check for any corrosion or other damage to the switch terminals.

Finally, you can reinstall the ignition switch back into the vehicle. Be sure to reconnect the wires according to their original routing. Once the switch is installed, start the vehicle to make sure the switch is working correctly. If the engine starts, then the switch has passed the test.

Bench testing your 1970 Ford F 100 ignition switch is an important maintenance procedure that will help ensure that your engine is running at peak performance. By following the steps outlined in this article, you can easily and quickly test your ignition switch to make sure everything is working as it should.
