An important step in figuring out electrical problems is understanding the circuit design of the circuit you’re trying to diagnose. Determining if the circuit is ground side or positive side switched is a good start when you don’t have a wiring diagram handy. In this video ScannerDanner and I talk about how to determine if a circuit is ground side or positive side switched using basic electrical troubleshooting tools. Now this does not come without some drawbacks as pointed out in the video, but it will still get you started if you’re trying to figure out an electrical problem. If nothing else this video shows some basic circuit design principals that you can use to increase your electrical knowledge.
Here’s some links.

Two great guys
Thanks 👍 Great video teaching 👍 👌

Positive and negative side
Not ground and power sides is the way it's taught professionally
How does the layman obtain diagrams for their car?
thank yo scanner and friend
Still a great video!!!! So much better to see this done practically than just learning the theory. Thanks guys!
Wonderful
Check this out … the Only 2 guys I'll look at on youtube , are buddies. They teamed up to try and further knowledge on a nightmare I've tried dealing with going on 6 mos now. Now , they need to use my car in a video. What say you oh sympathetic public persons out there in the world, say yes !
This is a great training video for technicians. This is better then most automotive shop training modules.
Two of the best automotive technician/teachers on YouTube Chris Fix and Eric O from south Main Street auto is also a good teacher you guys help me a lot on repairing vehicles at work god bless you two
And if negitave is ground were is it in ground on batteries touching ground at any time
So why is negitave ground if you touch both and you get zapped
another easy way to confirm a ground sid is siply set voltmeter to ohms and test each side of the harness to ground this can also verifit if your looking at a poor connection as your resistance will be higher
Since electrons actually flow from the negative to the positive you can think of voltage as an electron vacuum. Another way to think of it would be as potential flow. The reason that you measure 0 volts on a power side switch is because the voltage between the battery ground and your other test lead is 0. There is no potential there. Whereas the voltage between the battery ground and the other test lead on a ground side switch would be 12 because there are 12 volts of difference, or potential, between the ground and positive on the battery.
you must do more video together
13:38 instead of test lamp sir, you can use also multimeter by putting the one probe in positive terminal of battery and the other probe is for the wire you want to check.
Yes buddy my two hero ..GOD bless your family
If you put the meter on continuity, the side that is open should be the switching side or control side. Just a thought!
Mr. ERIC thanks for setting the stage on this subject
Mr. Danner, on a cooling fan direct control circuit. Is it ok to hardwire w/ fuse fan and switch my ground?
Love this man
That front camera angle looks like they're at a urinal
Superb explanation. Great instructional prop. Very useful tutorial. Thank you.
Great explanation I learned something new! Subscribed
Hey guys. I saw at least one of you wearing metal wedding rings. I really love Groove Life silicon rings. Give them your phone number to get discounts via text. Also sign up with your email to stay up to date on specials. They also just introduced an amazing belt. It's worth checking out!
BTW … I don't work there. Just a satisfied customer! 😁

Paul and Eric, you are doing a comendable job on educating us in the Third World countries,, thanks a zillion once again.
haven't remained with much – it's important to know which one is which, and you use a light bulb to sort things out.
So if im wiring a relay ground switched to my ecu i can wire both positives to the battery?
Thank you guys. Great video 👍
Scanner Danner and Erick the Car Guy The Awesome PILLARS of Automotive Diagnostics!!!, Sharing is Caring.God Bless!!!
Im following these guys, They are MAGNIFICENT!
Thanks 👍🇺🇸
From nicholas Ayivor from London England uk 👍🇬🇧
Love these guys I appreciate all the videos
