Re: [DML] Unprotected DeLorean Ignition Circuit

Several months ago, the aux relay was removed to ensure that the 
ignition coil was getting 12 volts not only during cranking but during 
other vehicle operation.

A few months ago, I replaced the car's spark plugs, I replaced the 
original ignition coil with an MSD "Blaster 2" coil, replaced the spark 
plug wires with MSD wires, and bought a new cap and rotor. Apart from 
the spark plugs, all of these supplies I got from John Hervey, and they 
all performed fine.

The work done to the car a few weeks ago -- just prior to Gettysburg -- 
was installation of a new fuel pump, fuel line, fuel filter, intake 
manifold, and carburetor. We also replaced some coolant and vacuum lines 
while we were in The Valley. Also, in order to take advantage of the 
high voltage setup, the spark plugs were re-gapped: from the stock gap 
of .028" up to .050". About 1600 highway miles later, the distributor 
cap caught fire.

I don't think we'll ever know what caused the fire, but the most likely 
candidate would seem to be the extra-wide spark plug gap. When I replace 
the distributor, cap, rotor, and wires, I'll re-gap the plugs down 
closer to .040". The plugs are only a few months old and they're in fine 

Meanwhile, I have named my car "Sparky." :)
