Default Very strange electrical problem - need some help

OK, this may be a little long, but I'd rather be over descriptive than keep things a mystery.

2006 Ranger FX4 4.0 A/T

On Thursday I drove home, everyting normal. It was raining pretty good and plowed through a decent sized puddle. Got home never noticed anything wrong. Friday I go to leave for work and I notice my door locks would not function from the key fob. I get in and notice the Securilock idiot light was on steady before I put the key in (normally flashes once every two seconds). I go to start and get absolutely nothing.

Later on, I had a buddy give me a jump and the battery would not take any charge and I would still get nothing. The only difference now was when the jumper cables were attached all of the instrument panel idiot lights were on (without the key in the ignition).

After work, I got the battery out and took it to get tested and charged. Battery was still good and now fully charged. After returning home and reinstalling the battery I noticed all of the instrument panel idiot lights were on again witht the key in and got nothing when I tried to start. I left it with the cables off of the battery terminals so it would not drain.

I did not get a chance to do anything with the truck til sunday except read up in my haynes manual. Sunday morning, first thing I did was remove the starter and get it tested. Works just fine. I came home and put it back in and connected the battery. At this point everything was just fine. Got in, turned the key and it fired right up. I drove to a buddy's house and stayed a few hours and then went home. Everything seemed good (even paying extra attention to everything electrical). Got home and turned the key off and removed it, but the truck was still running and the ABS light and the Emergency brake light came on. Put the key back in, turn it to on and then turned it off. Everything worked like normal. This morning everything was good and had no issues driving to work.

Just because it is normal now, doesnt mean I am not concerned. Anyone have any suggestions or ideas?

Water is the only thing I can think of that may have been shorting something out somewhere and it took a while to dry up. I did notice wetness underneath the battery in the tray and also in the grooves in the battery hold-down block (if thats what you call it), so I know water made its way up there.

If something shorted out though, a fuse or relay should blow and it wouldnt just fix it self right? And then there was the dieseling...

None of that had anything to do with your battery or starter. The security light being on steady is a dead giveaway. You got water into something that doesn't play nice when wet. I would check around under the dash and kick panels for a leak. It sounds like you got water into the GEM or computer. Once it dried, it was back to normal.

Pull the passenger side kick panel and check the Smart Junction Box (combination fuse panel/body module/security module). 2004+ sometimes have a problem with water getting in there during heavy rain.

OK, I have not had the chance to get into the passenger side kick panel, but it has not rained for a couple days and everything has worked great with the truck since Sunday. This morning (Wednesday), I get in, go to work, and go to turn it off once I am there. Well, the ABS light and the emergency brake light come on and the truck continues to run. I tried to turn the key to the 'on' position and then off again and it wont shut off. Finally, I turn the key just enough past the 'on' position (as if to start) and then turn it off and everything shutdown like normal.

I am no mechanic, but Im thinking that there is something wrong with the ignition somewhere (a switch, realy or coil or something) Anyone got any ideas?

Default Re: Very strange electrical problem - need some help

So, on Wednesday evening I get home from work and try to shut the truck off and it will not stop running. I tried several variations of turning the key and could not get it to shut off. Finally I started to pull a couple of fuses and relays that have to deal with starting and ignition. I did not expect that to cut the engine off, but what the hell. After doing that it only took a try or two to get it to shut off. I am thinking that something electrical was stuck and by resetting the fuses and relays I reset the connection because since that evening I have had no issues. Today (Friday) I had even made several stops around town which left plenty of opportunity for it to act up again (knock on wood).

If anyone thinks that resetting the fuses and relays like I did was a possible solution, let me know. If you think I am crazy and what I did had nothing to do with it, let me know there as well so I can continue to check out other things.

Anyway, thanks for the feedback I did get. It at least put me in the right direction.

There is nothing to reset with a fuse or relay. This had nothing to do with the fuses or relays.

Something was fucked up from getting wet. In pulling fuses and relays, you dropped power to whatever was fucked up and now it's fine. Kind of like unplugging your computer when Windows freezes. This is the only thing that explains your situation.

have you tried taking off the kick panels and using a hair dryer to dry out what may of got wet, I'd also do that under the hood..

I went thru a puddle the other day, it made my wipers come on for 3 days and wouldn't shut off..

the dryer helped..

Bob and Matt are right. The passenger side kick panel houses the Smart Junction box. Which is a fuse box + General Electric Module + Control Security Module. Look for a leak that can saturate that area or look for signs of moisture.

Here is a picture of it that Mykhael posted in an old thread about hooking up fog lights.

Ok, I am convinced that you guys are right and it is the smart junction box. Now my next question is how to prevent it from getting wet.

We had some rain today and the ranger is acting up again. I am looking for suggestions so I dont have to take it to a shop and pay out the wazoo for something I can do myself.

thanks

Cowl leak? Windshield leak? Not often easy to find because of all the stuff in the way. Unless you can spray it down and see where the water is coming in, you may need professional help.
