Hi CRG experts,

Voltage measurement at the coil is 12.52 volts, voltage measurement at the battery is 12.63 volts, a difference of 0.11 volts.

Does this mean this vehicle does or does not have a resistor in the ignition system?

Thx,
Jeff

The wire from the firewall connector to ign coil is a resistive wire - cloth covered by GM design.
A flashlight is a case for dead batteries.

It would appear to not have a resistor.
