In this video I show you how I make my own “test lights” of various amperage’s that can be used to substitute for a component on the vehicle that has failed. These range any where from .25amp to 4.5amp and can be used to replace failed fuel pumps, actuators, lights, solenoids etc. so you can preform circuit integrity tests. -Enjoy!

    18 minutes? So much for quick tip my god guess I’ll find a less rambling one lol

    question anyone here can answer for me regarding testing 5v refference or 5v circuits
    what if i hooked test light to a 5v source to test 5v ref and computer parts that take 5v by getting a 12v to 5v usb cigareete plug adapter,then cut a usb cord and plug this into the 12v to 5v adapter and find which wire is the power/ground and use this to hook test light when probing these 5v computer circuits? this would also drop some of the amperage draw from test light correct? would this be the way to go to prevent damage when testing 5v?

    Great idea 👍👍👍👍👍💯

    Old school systems of monitoring 3/phase industrial buildings would use 3 test lights, one on each leg to ground. These were left on all the time in visible areas. If a light started to dim, that leg would be inspected.

    Wattage divided by voltage should give you the amperage although I’m not sure if the wattage is stated on automotive bulbs. If this is a repeat of already posted info I apologize.

    I know that these type videos are hard to make in-depth, but could you talk about where you would use a higher amperage load versus a lower one? I've always used a test light to determine continuity.. What purpose would the various amperage ratings serve? Forgive me for my lack of electronic knowledge please, and thanks for trying to make folks smarter!

    — Throw a quick one back at you. Quick test for speakers in your car: Rig up a 9 volt battery with a couple of leads and ping the wires to the speakers. You hear a scratching from said speaker, that'll get you started on whatever issue you have. Then is a few seconds to switch over and test for ohms.

    Hey my name is David i live in Nova Scotia Canada I have a 2012gmc serria 1500 4×4 do you know how to get codes for ABS without a scanner
