Starter woes

Glad to found the issue!
I guess a positive is, you are now an expert on removing and installing the driver's side header:)
I just wanted to point out something in the mopar connection article that I thought was wrong. They showed filling a terminal with solder and putting the wire in. This is not a good way. The terminal should be crimped.
Solder has a low melting point and a starter wire can generate a lot of heat if the starter is used for a long time at a low battery voltage.
It is also prone to vibration which a car or truck sees a lot of.
Better to put electrical flux in the terminal, crimp it, and then you can solder if you feel it is necessary to fill the voids from contaminants.
Only use electrical rosen core solder not plumbing solder, which uses an acid core and can cause corrosion in the wires.
