so i went offroading in some mud, and it turned out to be way more mud than expected. but my battery light wont go off now. does anyone know why it is doing this and how i can fix it. thanks

 

Check and see if your terminals are dirty.

 

could be the alt. not charging the battery

 

^^^thats my guess...

 

terminals were dirty, the whole engine is covered with mud. i pressure washed it and the terminals and the light went away for about 10 min. if its the alt how should i fix that. and when you say its the alt did you mean i broke the alt, or theres mud on the alt and i should clean it

 

If the light went away, it was the terminal. From my experiences our alternators are pretty tough, I've yet to have problems with mine and I have put it thru some hard stuff.

 

haha alt's arent that bad.. changed 2 out in the parking lot of discount auto with 2 mag lights and 4 KC daylighters.. lol.... anyways.. go to autozone,discount auto etc.. have em put a load test on the system.. that should narrow it down to what it acutally is.. either way the alt isnt that hard to replace... undo the belt.. a few bolts and wires that go.. n pull it out.. if u need any help pick up a haynes manuel for like 18$ and should be a snap

 

have your truck running and hose out the alternator..some may start harasinng me for this but never any problems with doing it and whenever i got in deep mud my batt light would come on too and thats all it would take to get rid of it

 

More than likely you got mud inside the Alt. This can mess up the brushes and or slip rings for the field coil and or short the stator and or regulator. I'd say your gonna wind up having to replacing the Alt. to fix it.

 

Have you used a multi meter and made sure your battery is still holding 11-13 Volts? Then turned on the truck and see if it stays at 11-13 volts? It could be that your battery or alternator is going bad and it just happens that you went mudding. (the mud may not be your problem is what im getting at)

 

well im going to autozone and test the battery and alternator and the pressure washer and pray its the terminals. if it is my alternator, ill clean up my truck the best i can and take it to ford under warranty

 

so i went to the pressure washer and got the engine, alternator and battery very good. i dont know whether it was mud in the alternator or mud on the alternator, but after the 2nd wash the light was gone. thanks guys!

 

That happened to me a while back and it killed my alt., I think it was on it's way out anyway...

 

Is it ok to spray the alt.? I have killed 2 in about a year. The last one was FULL of sand from a day at the beach and the other had several miles and had mud in it.

Is the best way to clean them just spraying them with the pressure washer? I no that is bad for it and can kill it tho.

 

definitly didnt know that was bad for it. i sprayed it good with a pressure washer and it fixed it. because it was making a wierd sound before i washed it and it wasnt afterwards. does anyone know if spraying it with water is bad for it

 

Pressure washing the Alt is not a good idea. At a minimum it can force water and grit into the bearings.
