Does this scope have to be hooked up to the points, 120V, the battery
and
then inductively to the ignition coil or the plug wires? My father has
one
of these that he built and as far as cars go the only thing that it is
useful on any more that we have is an old super H tractor since
everything
has gone to electronic high output ignition. It would be interesting to
know if this could be used for coiling work since it is for the most
part
the one we have is would love to have a use again.
Thanks.
