| If one were to go off would a vehicle with points type mechanical ignition be ok? Does it only burn up solid state type stuff or would it be able to fry other things like a coil? |

Quoted:
An actual EMP would impact electrical grid infrastructure, not consumer-level electronics and gadgets. It would also involve a series of really, really big high-atmosphere nuclear airbursts... which I'm going to go out on a limb here and say would more than likely herald a bunch of problems a bit more serious than whether your 1971 Maverick fires up in the morning.

Quoted: won't matter battery will be fried. That's why you get an old school metal garbage can and keep a spare car battery, as well as spare batteries for your phones and other things. Or at least that's what the prepper in my family is telling us. I try to keep a straight face, and usually fail. |

But I saw this on Agents of S.H.I.E.L.D the other week on TV, it fried everything except the Dodge Charger. It makes sense, that if it could impact buildings and stuff, phones wouldn't stand a chance.

Quoted:
Thought there were bombs designed to cause widespread disruption of electrical devices without all the destruction of nuclear bombs. Only Russia and China *might* be able to do something approaching that, and doing so would be regarded as a countervalue strike with the similar economic and death tolls to direct strikes on population centers, thus it would result in total nuclear commitment. It is a fuck you on a same level as nuking major population centers and the result is a full exchange targeting population centers. It confers no military advantage. It is not a counter-force option. Anyone big enough to do this doesn't need or want to. |

Quoted:
Real-life EMP won't do much to cars, regardless of ignition method. Modern cars stand up just fine, at most they just stop and need to be restarted. One of the govt agencies (DARPA?) has done extensive testing on this. Would that be "The DARPA Initiative "? 
I'm lost...... |

I read an article about a year ago where both new and older vehicles had been tested for vulnerability to EMP, and several articles on the subject can be found via Google. Bottom line is that just about any car will operate after an EMP event, particularly if it wasn't operating at the time. During a test in the early 2000's, about 8% of running vehicles had their engine stall, with about 2/3 of those being able to be restarted and operated. Another 25% suffered some effects, typically problems with instruments but continued to operate. Upon shutdown and restart, the majority of those vehicles had full and proper function of their electronics. The rest of the vehicles did not show any effects from EMP during the tests. Of vehicles that were not running at the time of the tests, none showed any effects from the EMP upon startup. EMP testing started at around 10 kV/m, and went up to a maximum of 50 kV/m. During actual nuclear testing, EMP of around 5.6 kV/m was measured, which was lower than the minimum levels which caused malfunction during vehicle testing, although there are nuclear warheads capable of producing 50 kV/m or higher, though at the ranges you would see that level you would probably be more worried about the physical effects of the detonation (you know, being flash blinded or set on fire by the thermal pulse, and then blown across town by the blast wave...).

It's kinda the equivalent of starting a gunfight in an elevator.... by shooting your opponent through his Achilles tendon. It's gonna hurt like a motherfucker, but not keep both of you from getting the shit shot out of yourselves. |

You're talking about a movie-version EMP, right? Because a real EMP is not what you think it is. Than please enlighten us. I paid many thousands of dollars for my physics education, and I'm supposed to hand it out free to you? 
I mean, not even an offer of a pmag for a science lesson.

Quoted:
Thought there were bombs designed to cause widespread disruption of electrical devices without all the destruction of nuclear bombs. There theoretically are, but the energy a car or hand held device would pick up would not be enough to damage anything. If an item has a very large antenna, then it would be susceptible. Particularly anything tied to the electric grid with would act like an antenna thousands of miles long. |

I'm lost...... Testing was done in the 1980s by DARPA and the Air Force using the AF's TRESTLE EMP test facility. The results showed that cars with old carbon contact points-and-condenser ignitions died due to carbon crystallization from the EMP. Cars using "racing parts" (NAPA Echlin brand and Accel) brass contact points-and-condenser ignitions were not affected. Cars with solid state ignitions were also not affected, which surprised the investigators. In subsequent testing it was discovered that solid state ignition and fuel injection systems have a lot of EMP shielding built into their design in order for the electronics to operate in the underhood environment of spark plugs continuously discharging very high voltages (25kv-60kv). |

I saw a documentary where an EMP took the glow right out of the tritium. True story. Quoted:

I'm more concerned for my ACOGs. I need to play that documentary again. Been so long and I need recurrent training. |

Quoted:
Portions of localized power grids have been hit by solar flare induced EMP's in the past, causing regional blackouts. Always a good idea to be prepared for a week or more of no juice. Your car will still start though. The 1989 Quebec Blackout, and the much larger 1859 Carrington event are good examples of what would happen. |

Dodge realized there was an EMP threat and decided the only way to counter was to sign a massive ad contract with Marvel.

Other than all the doom and gloom, AND all the NASA guys saying we're all screwed... while owning or working for comapaines that EMP gov infrastructure, the reality is that most modern vehicle will barely even hicup, at most will stop and require to be turned on, or nothing at all. Thats what actual EMP testing has shown so far. Way overblown. FerFAL |
| I wouldn't waste time worrying about EMP events honestly. If one occurs, it's because major international powers are already at war. At that point you'll have more pressing issues such as the nukes going off everywhere. A super powerful solar flare is the most realistic thing to worry about, and that still wouldn't impact your car. |
