  • Q:

    On my 1973 Blazer, with new point kit, I have no primary spark from newer or older coil; coils test out okay on bench test. Maybe a problem with new points or condenser? There may be a ground problem in distributor, or there may be a problem with ignition module or pickup coil, not sure.

    Would this ignitor work regarless and simply bypass and take over the function of the ignition module and pick-up coil? I have 12.5 volts into coil and on distributor side of coil when ignition is on; points seem open on lobe; new cap, wires, rotor, platinum plugs, coil a year old but no miles.

    Was getting intermittant short, engine would start then lose spark, and the ignition to coil wire would get warm. Now, no heat build-up, but no spark out of tower at all.

    I'll buy this unit and maybe the coil to go with it if it will completely bypass the old original breaker point ignition in my 1973 Blazer (92,000 actual original miles on it).
