>> Lessee, knock box maintains 5v on sensor line.  Sensor produces a/c
voltage, so any change from 5v within reason means knox.  Mebbee test  lamp
to battery positive and sensor line, in rapid on/off fashion will  give
desired results.  It's what I'd try...12V seems high.

OK, for testing Distributor pick-up coils whatsa do?.  How about
holding your weller soldering gun right over it, and see if ya get
a spark.  Works best remote coil..

Bruce    Doc likes running the above tests, cheaper than going to
              someone who knows what their doing for his electro-
              shock therapy
