I have a 1984 302 convertible with a problem. It will quit when, for example, driving over RR tracks. When I raise the hood the under hood light will be out. If I shake the wires near the solenoid the light will come on and the engine will restart. I've replaced the solenoid but that has not fixed the problem. I noticed a large wiring harness connector near the solenoid that is also wiggling when I shake the wires. Is there any way to determine if this connector is the cause of this intermittent problem ?
