Electrical Troubleshooting Basics Part 2 -EricTheCarGuy Visit me at: http://www.ericthecarguy.com/ This one is not really a part 2 so much as a continuation of how to go about solving electrical problems on your vehicle. I try to follow a simple formula when confronted with electrical problems that way I have a plan which will increases my chances of success. Step one, check all the fuses. Step 2 find a wiring diagram and learn how the circuit works. Step 3 develop a plan for testing. Step 4 test and prove out the theory. Step 5 repair the problem. Step 6 verify the repair. Those steps have gotten me through quite a few electrical issues and I hope they help you too. Here are some links to other videos you might find useful.

This guy is GOOD!!! I am a electrician, I enjoyed the videos
-
if the module is providing a ground , could you just hook a test light to battery positive and check it at the relay connector ? or would that be risky to the module?
-
Your pretty good at explaining things to us dummies👍🏽 thank u
-
Hey Eric I have a 2001 Nissan Maxima, well the interior lights don't work head lights don't work power window don't work to. I already checked all the fuses and checked the relay also and I just can't figure out the problem can u please help me
-
I was going to leave an informational comment but I would just be advising younger know it all generations. Dick huh.
-
Wow Eric ur awesome.. this video really was exciting and helped out a lot..

You should also list causes for failure of relays etc. Like the fan you were talking about, yeah my fan didn't come on, but it was obviously the relay. BUT checking the amperage drawn/ohms shown, the fan was trying to pull to much power. So that's always something you check assuming its powering something such as a fan,a/c clutch etc. If its drawing to much amperage through it, or its got to much resistance it could be in need of a new part and a relay, or just a relay, assuming the amps / ohms are in check for the given piece you are diagnosing . But remember kids, if the resistance or amperage demand is to high for the relay,.. it'll fail another relay or control module. Never diagnose why something does't work, diagnose why it failed in the first place.

I'm not understanding why the fan control relay has a constant power and an Key-On power?
-
I'm "stealing" your stick pin idea to troubleshoot in my HVAC job . FANTASTIC IDEA!
-
I actually had a physical and verbal reaction when he stuck his finger near the condenser fan. I shouted "Get your finger out of there, Eric!" and I laughed at myself uncontrollably :D
Thanks for the entertainment, Eric, you daredevil. -
Thanks Eric. Your videos are great for a newbie like me. I read somewhere that wiring diagrams on conversion vans are next to impossible to find.
My van is an 93 E150 Cargo with an RV prep package (I think), converted by a company that's long out of business.
After the passenger conversion, a wheelchair lift was added, then removed by the folks I bought it from. They added a bed and did some interior work to create a basic sleeping area for touring the US in comfort but nothing else electrically.
I'm hoping that there are basically common electrical modifications to conversion vans that follow the original wiring in a logical way and really hoping conversion companies didn't get too creative and out there with the wiring.
Does that mean that collecting wiring diagrams from similar conversions might be worth while starting with the factory specs? -
Acura RL? I though it was a Crown Vic (patrol car) LOL.

Great channel ...I like Eric because much like me he's old-school and I will never depend on the ODB scan to Indicate a problem sometimes it's an easy problem that can still throw a code like a misfire code on the Chevy's most times it's a bad wire and I have fixed tons after people have spent Huge $$ on converters and sensors that was just unnecessary and all it needed was cut splice and solder a wire... so keep you hair in your head not in your hands and check all the simple symptoms First stay clean....
-
I like wiregram. it's an abbreviation that makes sense.
-
Good two part series! Learning auto electric is like learning a new language. It makes my head hurt.
-
Goog explained the wiring diagrams but the problem i think it was the fanmotor brushes you tap on the motor they start working again nice video
-
Thx great,Bob THE belgian
-
Would also be nice to know how many amps the fans are drawing. Well done sir, I like having the definite answer as well; that is what separates mechanics from parts changers. No boomerang vehicles, fix them once and fix them right is the goal.
-
i was wondering. how and where to get that electronic circuit map?
-
OMG that shield for ECU, it's like Spartacus mounted his shield there.
