Blowing starter fuse

Hey Folks,

I keep blowing my 40 amp starter fuse in my fuse block next to the battery. Any suggestions where to start trouble shooting?

The only extra electrical stuff I've added is my stereo deck.

Thanks and Aloha.

do you possibly have a bad starter? you could try putting in a larger fuse to fix the problem till you find out whats wrong

If you put a larger fuse in, you can damage your Jeep even more. You can burn the wires and what not out. Does the start work? Are you able to start the Jeep? There is a short somewhere. Keep looking and start cleaning the starter wire ends and make sure they dont touch . Make sure you pull the negetive wire off battery before you do any work. Hope this helps!

ditto on what xeon just told you. Starter cable or maybe a wire running off the batt.....if no luck i would pop the starter and do a bench test(take to you're local parts store and ask them to do it if you dont have access to the tools/meters most will do it for free) is the fuse blowing when you try to start or just turn the key on or even with key off?

When you take it in to get bench tested, make sure they do it more then once. Had a starter for a different car that the pinion gear would stick on once in awhile. This would cause it to over amp. But it didnt' ALWAYS do it.. On the third time I took it in to get started, it stuck.

i'd check the cables and the terminals for loose connections and corrosion before pulling the starter. either one can cause a voltage drop at the starter and cause it to overdraw on the amps. slice the insulation of the cables lengthwise at the ends and have a look underneath too. I've seen cables that look fine until you look under the insulation. start with the easy stuff

Right on fellas! I've blown 40 and 50 amp fuses as soon as I put them in. Only on one occasion did I put a 40 amp fuse in and the Jeep started fine only to blow it again 3 hours later.

I'm going to clean, inspect, and tidy up the connections and see if that does the trick. If not then I'll get the starter bench tested and probably just replace it since its probably due for a replacement.

Thanks again for the help!

Never replace a fuse thats blowing with a larger value, you could do some great harm to your electrical system. Does your fuse blow when you first put it in, or when you hit the key to start? Our Jeeps are getting old, so sometimes we have to repair things that other owners have done. An alarm taps into the starter wire under the dash ( most times) and if the connection is poorly done, then maybe thats causing your problem because it's shorting to ground. If you don't have an alarm , I would guess that your starter motor is going bad.

Good luck.

Ok I have the same problem, but when I put a new starter in, it will start. then an hour or a day or a week will go by and then I go to start and it grrr then nothing. Fuse blows.
I have changed my coil, starter, twice now and even had custom battery cables made.
I need some ideas here. I cant even start it and I am going crazy.
