73 Duster crank but no start / blowing in-line fuse on red ignition wire
FWIW, the potting material in some ECUs can deteriorate over time and leach out on their own. Opens the possibility of shorting out.
Here's one I had in a box for a long time and what it looked like several years ago after I "unstuck" from the cardboard...........
For kicks I put it in a plastic bag. What it looks like today..........
MyMopar has a '73 Dodge FSM free to download which may be useful if you don't have one.
