Mopar dies when key is released

1. How do you check a fusible link?

2. Should I be getting 12v on any wire other than the Red Battery Wire on the Starter relay when the key is in the "Run" position?

1--If you have to, get a pin or other sharp probe, and puncture the insulation on each side of the link. With key in "run" if you only get power on one side,it's bad

2--No. Starter relay is thus:

Largest stud is battery

"square" screw feeds power to solenoid on starter when relay is engaged

one "push on" terminal goes down to neutral safety switch on trans

Remaining push on terminal receives "start" from ignition switch
