Two Ignition electrical questions discovered during MSD installation
Every place marked V should be the same voltage.
If the Alternator out is 14.4 Volts, then all of the other locations should be 14.4 Volts.
A voltage drop of a couple tenths is to be expected. More than that indicates a poor connection along the flow path.
Of course the illustration is a points system, but the concept is the same with a ECU added.
Voltage to the coil should less than V when the key is in run position.
