No spark and i can only get 5V at the coil.

By the diagrams it says #1 is the Exhaust Gas Recirculator Vacuum Switch and #3 is the Electronic Speed Switch.

Running through the tests in the pub it mentioned testing those cavities with a batter that has at least 12volts. I have it at 12v before the ignition is on, as soon as I turn the key to the on position and it drops to 11.7volts and cavities 1,2,3 measure 10.8volts so it's right at .2 volts away from being out of tolerance.

I measured the resistance and across the top two pins and it has 5.6ohms and the bottom has 1.5 ohms resistance. Bottom seems a little high considering it is only supposed to have .5 ohms.

When you measure low resistance first put the ohmmeter leads directly together and note what the leads alone measure, then subtract that from the resistance reading of the low resistance part.

BTW, a 1.5 ohm ballast resistance won't keep it from starting and running but it will make the spark weaker. If you get the chance, chekc resistance of the coil from coil + to coil -; it ought to be around 1.5 ohms for this application. (Use the same technique of subtracting the meter's lead resistance.)

Is the brown wire from the ballast to the coil + coming off of the low resistance side of the ballast?
