Voltage in run at the Coil + 12volts, my ballast has the jumper wire on it.
During cranking the same post has 8volts now, after battery was recharged. I still not getting enough voltage to the coil during cranking.
Yur ballast seems to be hooked up wrong
Take a look at the drawing in post 16. See the little U-cutouts on the dual-ballast resistor? your plug connectors are supposed to have pins on them that orient them correctly on the ballast. Make sure yours are on there correctly.
Follow the circuits.
Ignition 2 is crank mode; notice how battery voltage comes thru the ig Sw and feeds the top right terminal of the DB resistor, then carries on to feed the coil battery voltage during cranking. Simultaneously battery voltage from the ig sw passes down thru the right side resistor and exits to feed A) the ECU a reduced voltage at the top-of-the-pentastar pin.and B) that same reduced voltage is fed to the ECU bottom left pin via the second resistor now in series with the first. So if either resistor is crapped out, it breaks the circuit in crank mode and you get no spark. Either nothing gets power, or the coil does but the switcher is dead, depending on which resistor is bad.
