76 Plymouth Valiant won't start
The fuse link "is" the wire with the marker tab on it in your finger
As vehicles get "later" in year, there are more, which is why in part you need the correct diagram / shop manual.
Sorry cannot tell what that is. It MIGHT be the red ammeter infeed going into the bulkhead connector? Refer to the simplified diagram
Again, I'm no help. I'll have to spend some time I BELIEVE I've got a manual for that here

You will also notice in picture 665 that what I think is the ballast resister is at the top of the picture (tannish rectangular ceramic thingy with 4 contacts coming out of it and 2 plugs connected to it... and a 7/16th screw holding it onto the firewall). Right?[/img]
Yes, ballast. Now this is where things get both sticky and sometimes simplified. The original ballast (you have) was designed for what is called the original "5 pin" ignition module, or ECU. "Sometime later" Ma redesigned the ECU into a "4 pin" which only needs a TWO terminal ballast. The only way to tell is to "ohm" the pins on the ECU and find out if the 5th pin is a dummy. This is NOT important for now, as you have a 4 pin resistor
The older 5 pin ECU REQUIRES a 4 pin ballast
The newer 4 pin ECU CAN use either a 2 or 4 pin ballast
Simplified diagram:
The diagram above, the far top right wire going off the page represents the "switched ignition" or "ignition run." What is NOT shown is an additional brown wire going to the coil + side of the ballast. This provides ignition starting power (from the key) "in start" for "hot" battery voltage to the system
