Question:
I have a very peculiar problem with my 1992 explorer. Once and a while when I try and start the vehicle it makes a single click sound (most likely from the starter relay), followed by complete loss of electrical power. Complete loss of power means that the ignition does not work, the radio does not work, the interior lights, hazards lights, etc. I mean everything. The battery is correctly hooked up and all the cables appear to be fine. The only way to regain power is to disconnect the battery and then reconnect it again. I am positive this is not a case of a loose battery cable. I have also tried to replace the starter relay with no change in the problem. After the battery is connected and reconnected all the power is restored. I can now attempt to start the vehicle again. It usually takes about 3 or 4 times of going through this cycle before the vehicle will start. Once it is started it runs fine and the power never cuts out while I’m driving. This is a very intermittent problem and occurs randomly every couple of weeks. Does anybody know if there is some kind of protective device in the car that is causing this to happen. Maybe there is a short somewhere. I am hesitant to take it to a mechanic because the problem doesn’t happen all the time and I’m sure it would be very expensive to diagnose the problem. Has anyone ever experienced this, Do you have any ideas?? Any thoughts would be greatly appreciated.

Make sure the battery connections are clean. Most likely the battery cable needs to be replaced. They corrode and get a high resistance inside the cable and cause this problem. Next time it happens have your volt meter handy, check the voltage at the battery, then the relay, then the starter. If it checks ok, check the voltage while trying to crank it at each of the 3 spots mentioned. If it’s less than bat v at the relay or starter then the cable is bad. It’s not an uncommon problem with these. Dave – Hide quoted text — Show quoted text ->I have a very peculiar problem with my 1992 explorer.

… Ahh, but it probably is! Get one of those tools that will clean the terminal & cable innard, apply it, and try again. I think you will lose the problem. Bill Funk All I ask is the chance to prove that money doesn’t buy happiness.

Ben, I had the same problem with my ‘94 about 3 weeks ago. I took it to a mechanic and he couldn’t find anything wrong. He unhooked the battery and checked it, but there was nothing wrong with it, so he cleaned the terminals and hooked it back up. I haven’t had a problem since.

While it is really not likely, it is not impossible that the battery has a bad connection internally. When this problem occurs again, put on the headlights to create a load and then measure the battery voltage at the terminals. If the voltage at the battery is low or nonexistent, you will know it is the battery itself. Charlie

replace the poss an neg batt cables,the cables look good from outside. I’ve change many sets for this concern.
