Re: [TCML] Fried It !

[Miles Mauldin <teslamiles@xxxxxxx>]

Been thinking about this since I originally posted "Fried It!", and there are a 
lot of interesting thoughts here from experienced list members.  I really 
believe it was Gary who pointed out the likely problem was the power cord being 
plugged.  Not that EMI was being leaked onto the power mains but rather 
providing a path to ground for EMI/P through the irrigation controller.  I did 
another run this week and successfully managed to not destroy anything or have 
any ill/weird things happen afterwards.  The protection was to remove all 
connections to ground form everything in the garage.

I'm not sure I am worried about the vehicles that much as it seems without a 
path to ground for any EMI/P. Years ago my car was struck but lightening while I 
was crossing a bridge.  Hit the antenna and came out through the front passenger 
tire.  Needless to say the tire was toast (blowout) but afterward even the radio 
worked just fine.

So empirically I can deduce that the alternating EM fields that come from a 
running coil, or EMP generated by something coil-wise, is a more powerful 
current-inducing mechanism than arc strikes.  Or it's somehow more directable 
around the vehicle's "faraday cage" -- presuming it has a conducting body.  (I 
would probably not zap my old Corvette with a coil...though the wife made me 
sell it, so it's a non issue.)
