[@ThePoxun]

Before this video I thought of fuses as just a closed switch with no (measurable) resistance so wouldn't have thought of measuring across them for a voltage drop... I guess now that I think about it it makes sense they have to have a small resistance as otherwise they wouldn't heat and melt when there is over-current. Today's random thing I learned.

[@TDG2654]

Closed switches also have a measurable resistance, everything does (except for superconductors, but unless you start working on MRI machines and stuff, you'll never have to worry about that)

[@Asto508]

Every current causes a voltage drop, it’s just a consequence of the current flow to equalize charges between poles. It’s the electrical equivalent to water pressure being reduced when you open a valve.

[@ouch1011]

Even the wires of the circuit have some resistance and cause a voltage drop. It's not big, but it exists. More current=more voltage drop.

[@ibbriley399]

Exactly right. The same principal is used for the precision measurement of current. A shunt with a very low but precise known resistance is installed in series with the load to be measured. The voltage across the shunt, which is directly proportionate to the current flowing through it, is measured using the appropriate voltmeter, and is converted to amperes using ohm’s law where the current to be measured is equal to the voltage across the shunt divided by the shunt resistance.

[@macdonaldsmotorworks]

Point #1. The voltage drop across the fuse only works on a solid draw, not intermittent as you can get burned if you measure across a fuse when the draw is temporarily off. Be careful how you use this test Point #2. How come you get the fuse and relay that's visible while standing?? I"m ALWAYS upside down in a underdash block (using my extra elbow due to yoga) to pull the component. Point #3. It's always the last fuse... sure it is.. we don't find the problem fuse and then say... ok there's the problem, now let's keep looking ; )) Honestly though Eric, your bulls eye approach is a great teaching tool and I truly appreciate the time you take for these vids... awesome!

[@edgarmaldonado2280]

I've always wanted to be a mechanic since I could remember, but unfortunately I procrastinated through my life. Now I'm 40 years old and I'll be attending Lincoln Tech next month. Two very talented, knowledgeable and captivating mechanics have reignited my spark to become what I always wanted to be, which is a mechanic. Those 2 mechanics are Joe from JOE'S AUTO ELECTRIC and the man himself, ERIC from SOUTH MAIN AUTO. I want to thank you so much for making me realize it's never too late. The only thing is that I know I could only learn, but so much in school and even though they have hands-on, the hands-on out in the world is more to grasp. Yes, he would be a great instructor.

Excellent diagnostic work, Eric! The customer is lucky to have brought the car into your shop.

[@kenny3552]

Nice dianostic. However, without a fuse box wiring diagram and knowing how to read it, it would be a bit more difficult. Good tip measuring voltage drop across the fuse to determine current flow through it! I learned a new word today 'spellamagician'

[@Blazer02LS]

The correct diagrams are usually the harder items to find in the process. Used to be a few free places but now it's a bit limited, unless you are near or have a library membership, many have access to places like Alldata, Motor or Mitchell. Or you can opt for the DIY side of those for about $30.00 bucks a year for single vehicle access.

[@gregwhite5058]

Your approach to finding parasitic draw really helped me find one in my wife's 1989 Ford Probe. Took the same approach you did to finding what fuse had current flowing. That allowed me to narrow it down to the radio. Turned out that the motor for her retractable antenna was drawing current. That antenna got broken off years ago so it didn't hurt anything to just disconnect the motor and problem was fixed. As a DIYer I would not have had a clue how to figure that out without watching your video.

How to fix battery that dies over night. Disconnect battery before night :-)

[@SouthMainAuto]

A 100% effective fix for sure haha

[@jws3925]

My first car was a 51 Studebaker and that is what we had to do every night-----unhook the battery. There was a dead short somewhere. My dad took it to three different mechanics, one that specialized in electrical repair, and they all said it was the voltage regulator (6v generator system) and so this car got three different voltage regulators inside of 4 months. The amp meter still pegged full discharge 50% of the time at engine shut down. We finally gave up and sold it to another teenager for $60. He inadvertently found the problem. Any guesses?? Intermittent short in the 6v battery!! He put a different battery in it and he said it never had the problem again. 9 months later he totaled the car. A fitting end to miserable automobile. I hated that car. Now, how did the battery develop a short? Well, not all teenagers knew that at the time not all cars had the same voltage electrical systems. In the mid 60's there were still plenty of 6v cars on the road. I guess when you own a 6v car and try to jump start a 12v car it isn't so good on the electrical system of either car or, in this case, the 6v battery! Who would have thought! The interesting thing to me is that none of the mechanics tested or suspected the battery. Every single one diagnosed it as a faulty voltage regulator. Actually, I am thankful for that because that meant I didn't need to drive that hog ever again.

[@davecc0000]

@@jws3925 Not possible the cause of high-current meter reading was the battery. If the battery had a short, the high current wouldn't leave the battery (that's the *meaning* of "short"), therefore it wouldn't display on the meter. That short certainly would kill the battery quickly, but if you saw a pegged ammeter, it wasn't caused by a defective battery. Possible the new owner inadvertently fixed the cause when removing the old battery and installing a new one.
