Ignition Switch / Starter Fuse keeps blowing.
I own a 2002 Ford Focus, 2.0l SPI engine. 5-speed manual trans. Recently bought from a friend's parents, with nothing wrong with it other than the clutch. I cheated when replacing the clutch, and completely pulled the engine/transmission out of the compartment, and took it apart that way. Got everything back together as it should be, but a few weeks later, I had no power other than dome light, "anti-theft" light, and a few other odd "emergency" lights. Found the blown 30A fuse, replaced it, and it blew as soon as I turned the key over, with an audible "pop".
Any help or guides to find / fix the problem is highly appreciated.
(On a side note, I'm not the mechanic-type, I follow Hayne's / Chilton's religiously.)
sounds like you shorted out something in the wireing,if fuse blowes as soon as you put it in you got a bare wire aganist metalmcausing it to blow,all you can do is retrace all the wires.
ok well what if it takes maybe a day or so for it to blow again, or somtimes it blows as soon as you try to start it? see, i got a 2003 ford ranger and the 30amp "starter/ignition switch" fuse keeps blowing at random times. somtiems it seems its fine, somtimes shell just die. any ideas?
you got a short in the wireing harness someware,check grounds and check for bare wires,also you could have put a starter wire on the pos,side of starter,that goes to neg,small wire to neg post on starter.
I found out what it was. When I put the engine back in, my starter / negative cable was rubbing on what I hear is the EGR tube(?). As it heated up, it melted the wire, and caused an arc. Burned a hole straight through the tube.. and was causing my car to short out. For those of you with similar troubles, check out your wire routing.
FocusTroubles pointed me in the right direction about the idea. Come to find out, there are some wires near my battery, that go to the MAF, touching the hot egr pipe. The last thing i did was changed the Positive battery terminal the day before, and apparently, moved the wire loom near the egr pipe, making clearance for battery terminal, to the point where its as show in the picture where its on the pipe. My symptoms were, the car will drive normal, and out of no where, jerk sort of violently, "i guess if you're going real fast, it will be worse", and the ignition will cut out - engine shuts off while driving. When you turn the key, no lights on the dash will come on. Below the hood, my 30 amp Ignition fuse is blown.
