I have a Craftsman timing light with positive and negative power
leads an inductive pickup. I connect the black power lead to the
fuse block (negative) and the read to a convenient ground (positive).
The inductive pickup does not seem to care about the polarity.

I bought a new ignition timing light and discovered when I opened it up that
it is meant for negative ground vehicles only. Getting the polarity right on
the main two power cables is obviously inadequate and the polarity of the HT
lead to no 1 cylinder - as sensed by the inductive pickup - also seems to be
critical.
Are there new affordable timing lights out there that will handle positive
ground systems? Ideas anyone?
