i at least hope there was some pant $hitting as a result. I’d have to say that from the perspective of being worth it, I’d probably think it was even though i’d probably need to do some troubleshooting.

@isis hit where I was about to go. Not in any way to counter what @FordTechOne is saying, but my first thought was how much current draw is that compressor, because from your story, you don’t know whether it was the horn blast, or the compressor.

can you elaborate on your wiring?
did you have anything else running when the compressor was running?
what’s the compressor’s current draw rating?
what gauge wire did you use?
are there battery home runs for power and ground?
how long are the runs to power and ground?
how long was the compressor on?

I don’t think the truck would even care about 40-60 amps for 1-2 minutes. [ damn... i can remember alternators that topped out at 60 amps ] unless something else was going on.
One of the reasons I installed the auto stop eliminator is that while my ~500 w stereo is playing, during the start up, the voltage at the amps drops to about 9.? volts, enough to scram both of them for a couple seconds.

if you have for scan, you can probably clear the alerts but they may come back if you repeat the process.

Valid point. I wouldn't think the compressor would overwhelm the charging system and battery, but it's certainly possible. We see that scenerio a lot on truck with snow massive plows; the system draws so much current that the instrument cluster and Sync screen power down and reboot. Once the modules see VPWR of 9.5V or less, they shut down simultaneously.

Ya, I'm pretty sure some people peed . . .
Wiring is good. I come from an automotive electrical background. All power is home runs and fused at the battery. I did ground to a common ground, so maybe I should relocate and isolate my ground wire for the horns. The switch is controlled through the upfitter fused switches. All power and ground wires are isolated. All soldered and shrink tubed connections with wire loom and zip ties. I will check to see if I zip tied my harness to a stock harness that may interfere, as that's all I can think of. I've been blasting these horns for over a year and never a problem. FYI, my third truck I've installed horns on with zero issues. My last trucks with horns were my '11 6.7 F350, '15 6.7 second gen, F350. I'll make sure to isolate my power wires.

So, I've used FORSCAN to customize my truck settings. How do I use it to clear codes ? I'd rather do it myself than the dealer.

There’s an option in forscan - it has to be pretty obvious, because I found it.

I did a short stint in electrical work myself so once in a while I tend to ... overlook the obvious. that’s how i caught the amps cutting out. Through my own confirmation bias, I just knew it couldn’t be electrical, I grounded right, ran the right gauge wire or better, no kinks, cuts, bends, battery home runs - so why the f*** is my stereo going out. then I put the gauge on it and saw it for myself. My options were capacitor, extra battery or A/SS eliminator. The latter, although slightly misnamed, was the least dramatic. I could not envision a place for a 2nd battery in the engine compartment and damn sure didn’t want that or a capacitor behind the seat.

I’m glad you at least got the desired result with the horn blast.

So, I'm pretty sure this hasn't been discussed yet . . . .

I was down in Huntington Beach laughing at all the crowds protesting.... Not just laughing, but blasting my train horns because apparently, the Coronavirus isn't in HB or nobody told them about it. Nobody was wearing face coverings and zero social distancing. So retarded.

I recommend people like you buy a Prius and just be done with it.

Anyways, after a few short blasts of the train horns at all the most precious moments, I decided to lay on a good long blast. ( After the air compressor filled back up ) So I hit the button hard and long as to completely empty my air tank ! It was REALLY loud. After I stopped laughing, I looked down and my dash is lighting up like a xmas tree ! Did my train horns trigger some type of sensor ? I guess I'm just lucky my air bags didn't go off. See the photos below for the errors and also the photo of the train horn layout as their location under the truck. The horns are under the driver / passenger on the drivers sided, mounted to the outside of the frame. The horn and compressor are mounted to the frame on the passenger side.

Obviously the truck is under warranty, but I still have take the time to it in to the dealer. I'm just really curious what happened and if it will happen again.

Ever heard of something called the Constitution? Didn't think so.

Yes sir. The 2020 6.7 has an upgraded/stronger rotating assembly, new high pressure fuel system, new cylinder heads, and electrically actuated VGT. The output rating is now 475HP and 1050 lb/ft of torque. It's a monster!

You're talking engine and not overall Gen 3 Raptor, yes? If so, when will that engine be available in a Raptor?

Yes, Gen 3 6.7 Powerstroke engine. You'll never see the 6.7 in an F-150, it's only suitable for heavy duty applications. The engine alone weighs over 1100lbs.

Fortunately, MOST people understand what is going on, how the pandemic has spread and can spread, how folks can be asymptomatic and how the government is not doing all the things it's doing because they want to, or are getting kicks out of using their Constitutional powers just because they are "tyrants" (as the cry babies are saying while they storm capitals with their AR-15, like they are actually going to pull the trigger, lol, please). Most Americans understand that the actions being taken are to help protect their citizens. Yes, there is a point about the economy, this is not lost on the State governments, quit acting like they want this.

MOST people, understand they have a part to play in getting past this ASAP and to get back to normal. MOST people understand that yes, the economy is being destroyed by this, but one of the alternatives is you have perhaps millions in the US killed, and an extension of the shutdowns into the years, instead of months.

Will all you "don't tread on me" "three percenters" stop crying if we open the economy and then in the fall we have a huge spike that shuts down the country even more drastically, will you join the team then or will you cry about YOUR constitutional rights, people's lives be damned?

Train horn-blasting Raptor owner making Raptor owners look bad = AR-wielding protestor making law-abiding gun owners look bad.
