Test Truck Ground And Power Wire With (TEST LIGHT) 

Great tip never thought about testing the grounds that way 👍🏼

I've got a 99 Buick LeSabre limited and my highbeam has been stuck since 2019 which has been draining my battery and amp power, but after watching your videos sent to me by eBay motors Kyle to be exact. My life has changed for the better. Thank you

Great video thanks for sharing 👍

Thats actually pretty clever

Will this be a good test to test for power and ground at the fuel pump hardness wire..

Pretty good. Probably be better to use a higher watt bulb?

Good on ya

My left headlight won’t come on. I’ve replaced the bulb and relay. Using a test light, I’ve determined that I have power and ground in the headlight socket. What in heck could it possibly be? Thank you

Jesus Christ, spit it out.
