Title: Coil and battery voltage measurements to determine if a resistor is installed
Post by: JGraft on April 06, 2023, 01:20:07 PM
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.

It would appear to not have a resistor.
