Electrical Problem for 1979 F-150

There is a black box in the electrical path I am trying to troubleshoot. I have a 1979 F-150 which won't start. Tested/replaced the ignition, starter, solenoid and it still won't start. Any suggestions where to check next? I am thinking it's the little black box (pre-computerized box?).

Have you pulled a plug out to see if its firing when you try to start it?Has the ignition got a 12v power supply when cranking the engine not just when the ignition is turned on?If it has those requirements it should at least try to start if the rest of the engine and timing is ok

Try Aftermarket starters make a lot of connections to the original wiring and it is unwise to remove it without knowing which wires in the original harness were affected.

What will happen to your car if a ground wire is loose

Whatever part, motor, or electrical load that ground is for will not work. For instance, a motor is an electrical load, put power to it -it won't operate without a path to ground after the load. A lighting bulb is an electrical load. Send power to it. and the bulb won't light, power will not travel through the bulb filament making it bright, without a path to ground after the bulb. Every electrical load has to have a path to ground, or it will not work-the reason for the term "circuit"-every wiring circuit (starting circuit, light circuit, ignition circuit, etc.) begins at the power source and ends at the power source. The ground completes the circuit back to earth (ground), and as you know, all grounds go to metal frame, and thus go back to the battery. If the circuit is not complete, the electrical load will not operate. See?

Clicking noise coming from the fuse box "under the dash" when I turn on the heat, now car won't start.

that item is called a relay switch. it toggles on and off depending on which electrical component it is connecting. if it's blown, they are cheap and easy to replace like a fuse, but you'll need to look at the fuse box chart (usually on the underside of the lid) to determine which one and where it's located. You can't look inside the relay to determine if blown, but you can replace them one at a time to test...
Also, if you're experienced in electrical, a paper clip can be used when the relay is out, to connect the circuit that you need. use tools and or gloves when attempting this method.

My ford explorer (1997) won't start. It makes the


The little black box and different colored wires lead me to think this is a universal Oxygen Sensor (O2 Sensor) that has become detached. If you can find the other end--strip the wire and use a but connector with electrical tape--should solve the problem.
Without the O2 sensor the vehicle does not know how much gas and air to give to the engine (won't start).

Hope this helps--
