I have a more significant question, why are you replacing perfectly good parts?
Throwing random parts at a problem does not tell you what's wrong. You need to check individual subsystems to find out why your car isn't running.
It's always down to the basics, ignition, fuel and compression. If you have all three, and in the right sequence and intensity, the engine MUST run; there are no other options. So to find out why it's NOT running, find out which of the three isn't right.
That's where a mechanic becomes a bit of a diagnostician.
If you want a car to run you don't just open the hood and start replacing random parts.
Most likely the problem is your alternator....the battery light actually does not monitor battery condition, only the charging system. I'd check the voltage regulator and the fuses first. The fuses are the cheapest fix and the voltage regulator will run about 25% less than an alternator.
ALternator fuses, if equipped may be on the battery post, in a fuse box, or in the wire going from the battery to the alternator.
its the alternator if the car is running with a battery light on. but check fuses first
Check the fuses
You have an open connection from the large alternator output post to the starter main battery post or fuses blown or circuits open feeding the alternator control wiring.
Have you drove the car around? Sometimes it takes the alt. awhile to "kick" in. Say around the block twice?
Check fuses first. If fuses are good, check the voltage from the negative battery cable to where the wire bolts onto the back of the alternator. (With the engine running). If you can't reach the back of the alternator, then measure across the posts of the battery. Voltage should be about 14 volts DC. If lower than that, replace the alternator. When you replace an alternator, it's a good idea to replace the battery, as a precaution.
Your battery connections and fuses may be fine but is your battery dead ? I drove to work one day and when I came out of work I had no power to anything. I used my key to unlock the door, opened the hood and even the little light under my hood would not light up. I got a boost, drove the Explorer to the dealer, left it running but locked, and when they tested the battery it had a dead cell, so they replaced the battery.
Is your battery dead ? or a bad battery cable connection ?
Have you checked the fuses?AnswerMay be a bad voltage regulator. alternator is no good without a voltage regulator. that's what "turns on" the alternator.
Most Chrysler products will not run with the battery disconnected, This is not a sign that the alternator does not work nessisarly. disconnect the battery and leave it, see if the battery itself has an internal short, allso disconnect the alternator plug and wire and leave it sit, do one of these at a time and see if you can isolate the drain, could be a stuck relay or under hood light, glove box light or trunk light. Remove fuses one by one until you isolate the circut with the drain and go from there.
check the fuses!
