hi john,

i can't say about the power supply one way or the other.  i just now
tried to verify it and i don't know.  i started with the coil
disconnected from the supply and measured the supply and it says 14
volts.  then i hooked up the coil and i can't get a reading anymore,
the digital meter just jumps around to different numbers and won't
settle out anywhere, i can't even tell what it is approximating.
