[MBZ] ***SPAM*** Slightly OT: EMP Preparedness

2018-09-26 Thread Greg Fiorentino via Mercedes
Recent information has been coming out about the vulnerability of the US to an EMP attack. I recall the press touting the "failure" of a NORK hydrogen bomb test because it had a low yield. I knew at the time that the test was no failure, but was about a very lightweight weapon that could be carr

I'm a diesel Ford truck guy, presently own 5. So, I may have some qualifications to answer your question. Prior to 1994, the International engines Ford used were Indirect Injection, with Mechanical injection pumps. The only electrical device which is EMP sensitive is the fuel solenoid, mounted on

How much of the truck is non-electronic? In general, I worry about the alternator and starter (no fuses in those circuits) on my diesels. I'm pretty sure the battery would handle a short but big pulse of energy just fine. Radio and instrument panel will be mostly dead (speedometer is mechanical

If your truck is 1992 and up, speedo signal is taken from a magnetic sensor that is mounted on the top of the diff, it counts teeth on the ring gear to give speed signal, so, likely will lose speedo input... If you have a manual trans, non issue... if you have the C6 auto, or the E4OD auto, both ta

Likely just radar. Military has some pretty high output radar in early warning systems and missile defense systems of about that era. Most likely, the magic ignition box was not shielded in any way from the microwave output of said radar... since it was a repeat event, and duration was short, about

Remember - all those wires going into and out of those boxes act as antennas - collecting EM radiation. You have to shield the entire system, not just the box boxes. On Thu, Sep 27, 2018 at 9:52 AM G Mann via Mercedes wrote: > Likely just radar. Military has some pretty high output radar in earl
