1993 Dodge Intrepid Question: Electrical Issues

 

Question

My husband bought me a small car stereo system (a 2 channel amp, very small subs, and two for the front doors). We installed all the wiring ourselves, and found out a few days later that the battery kept draining. SO we removed the fuse to the amp. About two days later (today), the car would not start. We tried jumping her, banging on the alternator, and nothing. We finally replaced the alternator, charged the battery, and off I went. I stopped, the car would not start again, so we disconnected all the wires to all the stereo things, and jumped her again. We had just gotten out of the parking lot, my gas gauge went haywire, saying I had no gas, then a full tank, then no gas, as such. I got home, killed the engine, tried to start it again, and this weird beeping noise came from somewhere in the dash and the park light you see in the dash was flashing with it, and the darn car won't start again! Long story, but I was hoping someone knew what was going on. Thanks!

    It doesn't take much when working on the electrical system to cause major damage to sensitive computer circuits. You may have damaged the Body Control Computer (BCM) and /or Instrument cluster.

    I agree with answer number 1. When you Install any Stereo/ amp system in a vehicle there are few guides you should consider. 1. What is the wattage of your amp/s 2. What gauge wire are you using for the power? I recommend 4 gauge w/ 30 amp fuse depending of course on the specs. of your amp. 3. Are you using a capacitor? You should be, High watt amps. (mind you oem radios are only 10 to 20 watt in most cases) draw a lot of current from your alternator. A cap. will help smooth out the current flow so as to not over tax your alternator. I would guess at 1/2 to 1 farrad for your application. 3. Last but not least , make sure you have good contact for your ground. DO NOT rely on the threads created by a screw , sand the entire area of contact for the wire or eyelet. One last thing NEVER EVER bypass your fuse it is there to prevent catastrophic failure such as that mentioned above. Also you will most likely notice that the oem connector does not match the color coding etc. of your aftermarket product. Best Buy and others usually have adaptors that will fit your oem connector and help you wire your unit correctly
