Gasoline ...A couple questions:

1- Are your key on/ engine off measurements in ohms or volts? It says ohms.

2- What is the measured resistance of the ballast resistor and the coil measured individually?

3- I'm assuming a 12V battery is being used ?

PS I did the math wrong with a 1.4 ohm coil it should be 12v/2.4 ohms = 5A, not 5.7 as I posted previously.

Is the multimeter you are using to measure the voltages a digital one?

If the 8140 without a resistor is connected to 12v, the 5.7 must be 12v or else there is something else in the path to reduce the voltage to 5.7. ( assuming the 5.7 is volts and not ohms)
