Does anyone know what the ac output voltage of an msd pro billet magnetic pickup should be. I am suspicious that the pickup may be the source of the random misfire I am getting. Everything else in my system checks out. I am measuring 596 ohms between the two wires of the pickup but only .68 volts ac when the distributor spins. I thought this pickup should put out more voltage. Does anyone know what ac voltage the pickup should generate? MSD tech line was not much help. Only gave an ohm value.
