Pierre nice to see the back-to-basics approach has solved the problem. Please, (I ask again) could you clarify if you are using the original pull type starter OR are you now running a solenoid activated starter? Even give a drawing of where you had all your ignition switch wires connected - from this we can most likely identify where things went wrong.
Fuse Block - Tagged #3 wire going to A3 on the fuse block. I'ts a bit hard to see but it is A3.
Now the next two photos show the #3 wire leaving the front generator/lighting loom & running around the front of the block to the coil SW connection. I disconnected this & just ran the HOT red wire that you see to get it running.
Lastly here is the instructions that show the wiring number system, in particular #3.
Now for some reason the wiring marked #3 that are going to the starter button & the run from the loom near the generator to the coil were all in a heavy black sheath covering. I assume this is because they are running close to the engine block.
The W/Shop manual wiring diagram states these as being colours Brown (starter button wire) & White for the run to the SW Coil connection.
Hi 600Dodge - No . With this wire disconnected I lose all the ignition & oil warning lights, This wire is the first point of contact with power from the battery. On the other side of the starter button is the direct wire to the starter.
You can do it with a test light if you hook power to one end and see if it comes out the other. The path I'm going down is that the ignition feed must have power on if the charge light is on when you turn the key but because it won't fire the power that should be present at the coil isn't there for some reason.
