Ignition/electrical problem

[Todd Wilson]

Well still no luck on getting the 74 Dodge truck to run.  I've changed stuff out and swapped and I still have no spark. It used to work and then not work.

Problem now is no spark.........I have 12 volts on the + and - side of the coil.   The 69 Charger points igntion and the 71 Charger e ignition  show roughly 6 volts on the + side of coil and little to no voltage on the - side.   I got 12 volts on both sides of the truck. So something is wrong somewhere.

I am thinking a short in the engine harness as I had an alternator smoke the harness many months ago and had to redo some of the wires. Truck has ran fine for several months after that problem but now is having this spell. Using the ohm meter  I have cont. from the - side of coil to ground when the key switch is off and when its on I have cont. to the positive side of the battery cable.


The truck has run fine for days or weeks. Its problem is the motor will just shut off.   If you can get the motor to run for 2 mins with out having its spell it will run all day.  You shut it off and its a crap shoot as to if it will start again. May start fine, May have a spell and fire back up or it may be dead in the water for a day. Come out next day and hit the key and it takes right off.  A week ago I shut it off at the house here and it has not started since.


Its got a new ballast,coil,pickup coil in dist.  and I have swapped ECU units. ECU has a good ground.

ANy ideas?

I'm gunna go with... dead battery 

doubtful, but would be funny.
I am also interested in what the actual problem was, negative side of coil to ground measurements didn't add up to me.
