Just saved this one from the crusher very clean- never had a dodge before, it ran but stopped running. im not getting any spark, changed coil,cap rotor,ign. switch and ballast. i have 8vdc on the coil when cranking. is there a particular way to test ballast and install( i hooked up as it was in the car with the jumper on the non notched edge. or maybe the pepboys cap is no good, and it does have a resistor on the coil, coil wire ohms out good, any suggestion would be appreciated thanks Don Nj junkman454@hotmail.com |

how about the pickup coil in the distributor? when the rotor shaft spinning there should be about .1 to .4 volts ac on the 2 wires. also the resistance of that pckup coil should be around 150 to 800 ohms. that pickup coil has a connector about 6 inches from the distributor. the p up coil sends a pulse signal to the ignition module which sends the pulse to the coil , than the ign coil increases the spark voltage and sends it to the spark wires and spark plug. |

How old are the ignition wires? If the coil wire has broken down inside its sheath, it may not carry the current to your distributor. |

Check the fusible links by the ballast resistor too. |

You should have battery voltage (or very near it) at the coil + terminal while cranking---the ballast resistor is (should be!) bypassed during cranking. Once the key is let off "start" to "run", current is routed through a second ignition wire, that runs through the ballast resistor, which should drop the voltage to ~8 volts.

ill check all suggestions on sunday, with chucks wiring diagram and my trusty meter i hope the old girl starts., i have my fingers crossed. |

i have good spark now, replaced the distributor ignition pickup, But engine floods out real fast, guess im out for a carb rebuild |
