I've had some electrical issues. I just got my ignition switch re-wired. BIG MESS!!! (see pics in gallery tonight)
I noticed that at the right side (looking at truck) where the harness attaches to the engine, the connection is COMPLETELY covered in oil!! dried up dirty stuff. Would this be a reason my alternator is STILL acting up? Or am I being picky? Be nice

 

What year and make truck are we workin on??

I reckon it could be the problem. Use some electra clean and clean all the gunk off the connections, then unplug em and clean all the pins. Be sure to disconnect the - tems on the batteries, or you take a chance arching some of the pins.

 

Its a '99 f250 SD. I'm still trying to figure out why it has so much crud on it (?) Its below the power steering stick......everything IS still disconnected, I wsa just checking everything 1st. GOOD THING TOO!!! My brother was 'helping' & forgot to connect the other side positive to the engine.
Will LPS no flash electro contact cleaner work ok??? Its the only thing I have at the moment.
check out the pics of what started all this.....idiots.....even a girl can tell its not right.!!
Thanks in advance

lps is a lube/oil. dont recommend using it

 

Bill youre wrong here....hes talking about LPS Electrical Contact cleaner. It will work just fine.

LPS Electro Contact Cleaner

 

and so your right Doc, all I caught was LPS. I see it doesn't leave a residue, so it'll work.
