What knocks the electrical power out when I turn the ignition? I get a click then nothing.


Asked by Aug 19, 2015 at 02:20 PM about the Ford Ranger

Question type: Maintenance & Repair

Turn the key, get a click, then all lights go out. I have to disconnect/reconnect the
megative battery cable to get the system to reset so the power comes back on. Then I
push start the truck and it runs.

Most common is dirty or bad battery cables, make sure the connections on the battery are shiny clean, none of that black corrosion.

Well, cleaning the cables stopped the ignition from knocking out the power. Now I just have to find the problem keeping the truck from starting.


Still could be a bad cable, possibly the one from the starter solenoid to the starter.


Is it true that leaking fluids can foul the electrical systems? I have a leak from the cap of the power steering system. I replaced the cap. What should I look for to determine what may have been damaged by the fluid leaks?

On a Ranger look for soaked spark plug wires on that side, you can run your hand over the wiring and and you will quickly find out the oil soaked wiring, sometimes if they aren't too bad some engine degreaser will help.
