Bought a 78 Ford Fiesta as my first new car when working at a Cadillac Factory.
It was really nice not to have to constantly be working on the ride.
After about 6 months, it crapped out. It would start with the key in the crank position, but would stall out when the key returned to the run position. Did some probing and found that I did not have power to the coil in the run position. As I needed transportation, I jury-rigged a wire from the coil to an alligator clip that I would connect to the battery B+ to run the car, then disconnect when the car was off.
Worked just fine.
Then, one day, when I was helping my former Auto Shop Teacher with his SCCA race car, he saw my setup and said, “That isn’t right. The wire that failed is a resistive wire, which drops voltage to the coil. You are going to burn something up running straight VBAT to the coil.” So he helped me rig up a Chrysler dropping resistor in the circuit, and we ran a lead to a switch inside the car so I didn’t have to open the hood every time I started or stopped the car.
It worked great, I was golden!
Then one day, while I was sleeping (Second Shift was 4:00 PM ~ 1:30 AM), my dad tried to move the car and it would not start because he didn’t know about the switch. He wakes me up, I show him the switch, and I move the car for him.
The next day, he asks, “Why do you have that switch in there, to try to keep the car from being stolen in Detroit?”
I explained it all to him, then he asked why I didn't take the car back to the dealer to have them fix it under warranty.
It never even dawned on me that the car had a 12/12 warranty.
BTW, that car was a blast.
Looked something like this.
