No Spark help
Just finished installing my 318 into the 1974 Duster (/6 originally).
Tonight we decided to try a test start to see where we are and there is no spark. I have test with a spark plug to the #1 plug wire, as well as I tested a spark plug from the coil plug on the distributor neither have spark.
I have a 5 pin ECU with a double ballast that all ran before I pulled the /6. Can someone tell me if I am missing something or have something wrong.
I tested the Ballast the top 2 pins are reading 5.5 Ohms and the lower 2 are 1.4 Ohms so that is still good.
My coil is testing post to post 1.6 (recommended .75 to .81) and positive to coil pick up 8.1 on a 20K reading (recommended 10k-11k) So I am going to replace the coil for sure.
My question is since the car already had the electronic ignition what do I need to add or change for the 318. I have attached pics, but the 318 had a small ballast on the coil mounting point - Is this still needed? This tested at .3 Ohms but cant find any recommended numbers for it.
Also on the opposite side it looks to have an isolator for the negative side?
The current wiring is below:
Alternator has blue and green wire - Both run to the voltage regulator. Blue wire continues to the small Ballast.
The other side of the the small ballast has a brown / white stripe coming from what looks like the firewall connections (I can better trace it tomorrow if needed)
Coil
Negative has a black /yellow stripe that connects to the ECU, as well as the black wire running to the isolator.
Positive has a solid brown wire that runs back to the engine harness connector. (haven't traced that one yet either)
Should I be getting power to the coil once the ignition is on? Would this be tested just off of volts from post to post of the coil?
Also is there any additional wires I am missing? Like from positive to small ballast and negative from coil to distributor body? I only ask because it have seen it both ways on different diagrams.
Let me know if you need more specific pictures as well. Thank you and I'm stoked to get this guy fired up and broken in soon.
