Chrysler Repair: Starter fuse keeps blowing: 2000 Neon, amp fuse, chrysler neon


Question
My starter fuse blew about a week ago for my 2000 Chrysler Neon. I bought some fuses and replace the starter fuse. A couple days later I stalled while driving. I then tried to start the car and it wouldn't turn over or even make a sound. I then replaced the same fuse and my car turned over. The next time I took the car out it happened again. I replaced the fuse again and it was fine. I took out my car for a drive the next day and it happened four times in the matter of minutes. Is a wire short, or is there a bigger problem? Please help. Joy.  

Answer
Hi Joy,
When you write "starter fuse" I have to assume you are speaking of 30A fuse #11 in the power distribution center under the hood. If that isn't the case, let me know.
Because the car died while driving, it has to mean that something other than the starter motor circuit is blowing that fuse. Unfortunately, there are three wires powering 10 other fuses and a circuit breaker from that same fuse #11 while you are in the running mode. So the question is whether one of those three wires or which one of those 11 possibilities is blowing the 30 amp fuse, although one those fuses and circuit breaker should logically blow first because they all have lower current limits Except the circuit breaker for the power window which is a 30 amp unit so if there was a short in the power window circuit it might blow the fuse 11 before the circuit breaker goes. My inclination would be to remove that circuit breaker, located in the far end of the fuse box under the ash, below the fuses, and then see if the fuse 11 blows again when you are driving. If it doesn't then the power window circuit has a short. If it does, then we have to look at the 3 wires from the igntion switch that go to those 10 fuses and see if one of them may be shorted to ground. My inclination would be to measure at the plug for the ignition switch the resistance from pin 8 (black/white wire), pin 9 (dark blue wire) and pin 4 (black/orange wire) one at a time to ground (any part of the body structure near by) with the ignition switch in the off position to see if any one of those 3 wires has a very low resistance reading (like below 1 ohm, try shaking each wire just in case it might be grounded intermittently). Then after that we have to remove the fuses that are powered by that specific wire to find out which component is overdrawing the fuse #11 or find the short in the suspect wire. Something related to the 3 wires and l0 fuses is blowing fuse #11.
Let me know if I am incorrect in my assumption about which fuse is blowing.
