I really like this video. For anybody curious about this, search 'flyback diode'. When an inductive coil is suddenly shut off, the magnetic field of the coil collapses. Energy from the collapse 'tries' to maintain current flow through the coil in the SAME direction it was originally moving. Interestingly, if you had your scope on the input side of the coil you'd see a huge NEGATIVE voltage spike, almost as though the coil is turned into a battery, releasing energy to keep flow moving in the same direction. That negative voltage spike can damage sensitive electronics, so engineers add a flyback diode to allow electrons a one way gate (the diode) to pass directly back to ground and smooth out the dangerous spike. Since these diodes can burn out, they were installed in such a way as to allow easy replacement.

Great video. Some valuable information here 👍

Very informative. I enjoyed this video

Were those Hankoook Dyanpro tires stacked up there? got em on my Tundra Love em Great tire so far

Nice power probe, what model?

5:00 your description of a diode is kinda incorrect. A diode is a check valve but for electricity, when the ac coils field collapses it can send the high voltage spike backwards down the line and the diode stops it from going any further.

I see where you’re coming from, and I’ll admit I didn’t do a great job describing a diode in this video 😂 however the way the diode in this particular circuit works (3:48) is it acts as a one way resistor, which is why it’s connected to the compressor circuit on the anode (positive) side, and connected to ground on the cathode (negative) side. It stops low (11-14 volts) voltage from passing through to prevent the fuse from blowing, but allows high voltage spikes from the collapsing coil field to pass through to ground.

@@DanielJaegerFilms It's not the voltage, it's the direction. When the magnetic field collapses, it will generate a voltage of the opposite direction. Being opposite, the diode conducts. Battery voltage, it's open. Magnetic field collapse, it conducts. Direction, not voltage.

my grandparents once had a major problem with the dash A/C on there RV. the Compressor froze, and broke the serpentine belt. and it melted the meddle around the Compressor.

Wow! Chasing ghosts! Makes it bad when others have messed around which makes you look bad. (Plus can you charge for your time & will the customer understand the issue is bot your fault?) Anyway, glad you got it going...again!

Finally, some more Daniel Jaeger videos!

I just spent over $1300 rebuilding my whole AC system on my Grand Marquis, first I had the evaporator replaced because it had a leak, then I had to replace the compressor because it decided it was a good time to self destruct on the drive home from the mechanic, it had 224K on it, owner before me replaced the condenser right before listing it for sale because it had a bad leak, so it's got a whole new system now

Any update on the vw duel mass flywheel?

Once it hits 260k miles it’s getting the flywheel, timing belt and a few other things done. It’s at 257k miles now so it won’t be long!

Is that clutch not adjustable?

Hey there. Sorry to ask, I just burned 60$ for a junk diagnosis. I have a 2003 town car and the ac clutch keeps kicking in and out. Got it checked they said the charge level was fine 85% and it does blow cool air, but it's definitely not where it should be. Do you have any thoughts? Thanks

Didn’t you have to take down a lot of videos a while back?

So did it actually need the compressor ? Are they not adjustable.

Shot the parts cannon and failed

Did you charge your customer for the new A/C compressor? It obviously wasn't the issue. I like your videos, but I can't believe you replaced the compressor without even checking the fuses first.

its called a clamping diode and many relays have them built in, not sure why ford has it seperate

I was truck shopping for a month its crazy how many of those junk 5.4s are out there.

I’m not exactly sure what the other mechanic did to the truck, but it seems to me the compressor was the original problem due to the worn clutch, and while diagnosing it they removed the diode and reinstalled it incorrectly.

That’s a nice looking truck for 200k
