Says the Internet. Repeat a lie often enough and the feeble minded will believe it. Tests show that cars can be interrupted by EMP but not damaged. They restart just fine.

shoot straight - stay safe
This is actually depends more on location and what type of emergency caused the EMP. with a CME most things will be disrupted but bounds of society will most likely hold at least locally where a vehicle would be useful short term. As for a Nuke, chances of survival are slim in the blast zone and outside the blast zone will likely be crawling with soldiers and checkpoints on defcon 1 chances are you will either die, be stranded, or get detained.

As for location, EMP or not where I live we have high risk for wildfire. 90% of situations would constitute a bug In response but if a wild fire gets near the perimeter EMP or not it's time to cut losses and bug out. Even if it's a one way trip having a vehicle is beneficial for emergency escape.

Whether or not the cars will run, will there be fuel available to power them?

In 2002 We bought a mail order still. Since then we have made 3 more.

All you have to do is change the jets in the carb. We have those jets.

Also with millions of dead vehicles, a punch and a drain pan is all you will need.
Bolt cutters, a 40 foot rod with a hose, attacked to a Holly electric fuel pump will draw about 5 gallons a minute.

You just dont get the ding ding sound as you pull up to the station.

BTW this is not some hair brained idea. It was taught to us border rats in case Ivan crossed the DMZ. We were to hide our tanks for 3 days, and pop up and shalaylee missile the poggies out of the rear supply lines.

Default EMP Strike Starters and Alternators

I don't think any but a mechanical diesel will give any service. I'm fitting out a 6BT 12 valve. Considering any 12V battery survives, how do we find an unfried starter? An air burst 10 megaton energy weapon likely will melt all copper windings. Alternators have copper windings with even less shieldings. How would we then start these vehicles? I personally WILL be in the 1860's. Diodes are the first thing to go. I thought of Faraday cage over a few alternator diode trio circuit boards. Perhaps that isn't enough shielding. Strength of the EMP is what nobody can predict. If this air burst happens over Taiwan it will likely fry all LED light bulbs and all chip controlled appliances far into the west coast. We all have copper wire. It's usually stored in a coil on a plastic spool. Will it melt on the shelf ? (or start a fire).
The military now suggests shielding of 6mm 1/4" welded steel plate. Not Copper sheet, not brass screen, 3/8' Aluminum is a second choice but many days of heiliarc I don't think many of us could afford.
I'm buying old cast iron kettles, big enough to de-hair a hog. To me, it's an easy way of putting a few CB radio linears and modern lighting at least in it turned upside down. Starters and alternators too?

The engines on the Enola Gay and Boch's Car did just fine in the vicinity of an A-bomb.

Yes, no chips is a good option, or spare chips in a Faraday cage.

You might need to park your diesel on a hill so you can roll start it because all the batteries in the area exploded from the blast and pulse.

If your coil of wire (inductor) starts a fire, then its was way too close to the blast anyway.

I think starters and alternators will be fine for the most part.
And vehicle batteries almost certainly will be fine.

Delicate computer chips might get fried, or might need a simple power off/on cycle to recover them.

I think it is reasonable to get a spare ECM and other can-bus devices, get them programmed for your vehicle, then store in little galvanized steel ash can with foil tape on the seams.


If you search, there are a few threads on here going into more details by folks with more background in EMP than me. I think the consensus was that most vehicles will likely restart after an EMP if you disconnect the battery for a couple minutes, then reconnect.

It all depends upon your proximity to the EMP, and how much "antenna wire" is hooked onto your system that can collect EMP and conduct it to the semiconductors.

This is why I got myself a 1970s Moped, and a 1970s Motorcycle this year. Not just that they have no chips and run on points, but their gas mileage is outstanding.

I don't buy the few tests that I've seen on EMP no damaging cars. I've seen a few, but they shared no information on a technical level, explaining - how the pulse they offered compared to actual EMP either man made or natural. I wanted a couple older toys to work on anyways, so - fun for me, and it gives me more possibilities, even though there are no guarantees and nobody can tell the future.

"You all do know that all motor vehicles newer than 1972 are prone to never running again. Newer than 1992 scrap metal."


So, as an electrical engineer you can tell us all how that happens? No, not an electrical engineer? Just someone who read it on the Internet?

I am an electrical engineer who has EMP experience and I know for fact that no car will be destroyed by EMP. It may be interrupted, but it will restart just fine.

Even our 79 Chevy and 84 Ranger have to have parts put in a Faraday cage.
Ign module and alternators. After 92, you have to deal with computers, even newer, sensors.

Nukes are in the worlds future. Be prepared.
You just like posting stuff that everyone has known for decades? Be prepared. End of discussion.

Some good information on the effects of nuke EMP's on vehicles, including "Starfish Prime."

Quote:
Many of the effects of nuclear EMP are very difficult to predict on the 21st century United States. Many vehicles that
one would expect to be disabled by an EMP due to their dependence on sensitive electronics might be shielded well enough
to continue to operate. Automotive electronic ignition systems in general are much better shielded and protected against
EMP than other electronics. (After all, the purpose of an electronic ignition is to make high-voltage sparks.) Circuits in
the automobile outside of the electronic ignition are actually the most vulnerable. Actual tests on vehicles in simulators
have been very inconsistent. Even if only ten percent of the automobiles on the highways during the day were
abruptly disabled, the resultant traffic jams would be nearly incomprehensible. (Having ten percent of the cars
suddenly disabled might actually be more chaotic than having nearly all of them suddenly disabled.) Of course, there is
no practical way to do a real nuclear EMP test. Even a nuclear test in space over the Pacific would likely do billions of
dollars in damage to today's electrical and electronic infrastructure in the Pacific region.
Tests done on 37 vehicles (that used electronic ignition systems) by the United States EMP Commission showed that all of
the tested cars would still run after a simulated EMP, although most sustained some (mostly nuisance) electronic damage.
Only about one in every ten million civilian automobiles and light trucks in use today have been tested in an EMP
simulator. That is a very tiny sample size. Many cars that would run after an actual EMP would probably have to be started
in an unconventional manner (such as temporarily jumpering wires under the hood) due to damage of control circuits.

Obviously, you've never been to one and English isn't your first language. The word 'interrupted' isn't so hard to understand.

As has been repeatedly stated, an EMP will absolutely fry modern electronics, cars included. Vehicles after the 80's will likely suffer ill affects. Anything modern will be toast.

Hear it for yourself from the leader of said commission. He say they absolutely could have destroyed the testing cars, but didn't- here's the link.

It's an interview with Dr. Peter Vincent Pry and another member of the EMP commission.

http://www.blogtalkradio.com/empact-...er-vincent-pry
Linked From
https://www.futurescience.com/emp/vehicles.html

At minute 47:30+
'Cars were borrowed and could NOT be fully tested. As soon as something was starting to fail, they stopped. They couldn't afford to buy 25 cars/trucks to see them tested to the full EMP levels.'

Around minute 50, a summed up quote is; 'Since we saw cars failing at surprisingly low levels of an EMP, the commission knew that we could have destroyed many cars, but couldn't afford it.'

So to anyone who thinks their new car would be fine; no, no it would not. It would be a paperweight. That's from a Congressionally appointed task force to study the phenomenon, not some internet rando.

Total BS. Starting with the idea a airburst is going to melt copper, without also melting the body and setting the tire on fire.

That will leave me with my old farm tractor. I'm good with that. Quick trip to the market. I wonder if Bertha down the street will mind if I pick her up for a moonlight ride on the tractor? I could always mount a granny seat back there around the PTO I think.

Just take the blade, blade safety cover, and belts off your riding mower and get moving. Oh and stop whining about new cars. Buy an old one if you're afraid of an EMP or again, just hop on your mower and get moving. Or just have any mechanical knowledge at all. A basic ignition is super easy to swap out and run wires. There is more to it of course but I don't want to go into everything needed to bypass a computer but engines aren't that hard.

Wow, all of these people thinking an EMP is merely an inconvience or an interruption.
Tell you what, don't prep for it, see how that works out for you.

The worst case scenario for which survivalists should prepare is that nearly all vehicles remain operable...so streets, roads, highways, Interstates are clogged with vehicles going nowhere, idling until their fuel runs out.

So there won't be convenient sources of fuel as close as the nearest road, just dead vehicles completely drained of fuel, rendering roads impassable to anything with more than 2 wheels.
