I have a 1971 mercury 500 all wiring been replaced, motor runs and idles fine. Did all tests for switchbox, rectifier, high and low coils and big coil pack, but for some reason when i hook my voltage meter up (one probe to cowl and other to block) I show voltage between 3 volts to 190 volts jumping up and down why would this be? Motor has good spark, new rings etc. rebuilt. High and low coils read 415, 415, 10. Just the voltage to block problem could someone please help or is this normal?
