Electrical Troubleshooting Basics - EricTheCarGuy

I get a lot of questions regarding electrical issues so when this 1994 Geo came in I thought it might be a perfect opportunity to show some of the basic steps that I follow when confronted with an electrical problem. Keep in mind that electrical problems come in all shapes and sizes so there really is no 'magic bullet' here but if you follow a basic procedure like the one shown in this video it might help you find and repair the problem. Here is a video that I did some time ago on soldering wires.

DUDE, my 99 chevy k3500 didn't crank over yesterday morning, and watched one of your videos and with your expert tips I got it to crank over and got it started! I am no mechanic by any imagination but your tips got me out of the NATIONAL FOREST and homemade safely! Thank you a million times!!! Ivar, Uncompahgre National Forest, Montrose County, Colorado

I love the way you diagnose problems, it is so methodical and thought out.

Very professional, very informative and very well spoken. I've worked on cars for a good amount of time and these are very well put together videos. Thank you for your input and time spent making these.

Great Job Eric! I'm trying to show my grandson about this stuff and I'm finding it maddening to explain things that are so clear in my 65 y/o mind, in words that make sense to his 17 y/o brain.. You videos are helping alot! Thank you for that!!

[fwijffels]

I just started college, Automotive engineering. I'm watching your videos for a while now and I really think they can be a huge help for me! Thanks Eric!

Eric, you're a hero that never wears a cape. Keep up the good work dude! This video really helped me to understand the basics of my electrical unit. Thanks!

Why go school when I can learn everything right here for free.

Thanks Eric.

that was the most helpful video that i have seen, I feel like i can actually try and fix my car by myself, that was great and the direction you gave me was awesome, my father use to work on cars and has given me a little idea of what i can do but you gave me a good base to try my skills on, thanks alot

Thanks for this. We replaced everything when the blower shorted in our car and fried the control panel. But never checked fuses not related to the HVAC. After watching this, my husband went through all the fuses and found one blown that we would have never thought would have been the issue.

You can also use a standard multimeter as a power probe. If you use a gator clip to ground the black lead, the red lead should act as your power probe. 12v coming into the fuse, 0 volts coming out would indicate a blown fuse.

Thank you for this vid. I appreciate all the helpful tips and tricks I can get. You are ABSOLUTELY right about watching out for body work. I purchased a truck with a new paint job, and that evening I noticed I had no hi beam headlights. I bought a pair of new headlights and installed, still no hi beams. That's when I found out the truck was a front end collison repair and someone had twisted and taped the wires in such a way I'm amazed the headlamps worked at all. Thanks again, I don't comment on all your vids but I am thankful you're making them.

Hey Man im currently going to school in automotive engineering. You have really helped me get a jump on knowing what i am talking about. Keep doing what your doing. Cheers from New Zealand

[FEEZY]

Wow this video was published in 2012 and It's still helping people 7 years later..I love YouTube and people like Eric👍

[HellssBells]

hahaha. I really like the "well there's your problem there!" moment.

TIP for a draining battery with key out, ignition switch off.
Put a small light bulb on the battery across the disconnected positive. The drain will light the bulb. Pull and replace fuses till a pulled fuse turns out the light. You then know the circuit the drain is on. . Found a retracting power antenna trying to return down to home. Thanks ERIC, love your stuff.

I'm going to graduate from Eric's Youtube school!! Thanks man
