https://stream.echo6.co/videos/watch/e9d0fd4c-e376-4d52-a4e1-8c2f8f5dbb1d After my recent video covering a no crank condition on a Dodge Neon, I felt it was important to cover test light current draw, and why it’s important to understand. There’s a lot of confusion in the industry about ‘computer safe’ testing, incandescent and LED test lights, and I hope to provide some answers in this video. Engine Performance Diagnostics chapter 3 page 9 Topics discussed measuring the current draw of a test light with a digital multimeter, comparing incandescent and LED test light current draw, why incandescent test lights work for bypass testing, how current draw relates to computer transistor drivers, Tools used digital multimeter, incandescent test light, LED test light, Playlist (Chapter 3) Transistors, Solenoids, Computer Controlled Output Testing https://www.youtube.com/playlist?list=PLE9BA8CBD51B8C48E, Related videos -How to troubleshoot a starting system (bad ignition switch) - Dodge Neon https://youtu.be/TY4TzfacFkI How to test a fuel injector circuit with a noid light (a ScannerDanner Premium video) https://youtu.be/FAipVwCdwSQ, How to test an ignition coil with a test light (Nissan C.O.P design) https://youtu.be/UwQVg0CtkuQ, Ignition coil-module test with test light (a ScannerDanner Premium video) https://youtu.be/jJmqdhhduVc, How to troubleshoot a no spark condition with a test light (Subaru) https://youtu.be/YBE7c7lfmnY, For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.
