I have 2002 Mitsubishi Motero sports LS AWD 3.0 lt. I am facing a weird problem. Please help me out as I am baffled and stressed. Problem: I changed the battery a new one as soon as I changed battery at firestone, battery symbol came on dash board and when I pressed accelerator paddle, i goes off. It is like this and I ignored. All of a sudden after 10 days car not even start. I jump start the car kept running for 10 mins and tried to drive and within 5 mins it died. I also changed the alternator and tested battery and alternator. Still it doesn't charge and battery symbol is on. What worst is...... my electrical's don't work like if I start the car, my stereo and my AC & not even fan doesn't work and it does start working after 1 min. If i try to lower down the power window, stereo and fan stops. If I press brake paddle, stereo wont work . Also, all of a sudden when I changed alternator, the same day a jerk started to come when I shifted the car in reverse. Also, my neutral gear light is flashing in every gear. Please help me out in solving this problem. Too many weird things. I am literally crying here. Please help.
Have you checked all wires? 1. The ground 2. The power wire to starter. 3. Wire feed to both fuse boxes. 4. Main power fuse might be lose sometimes auto shops will pull the main fuse to the car and not push it in all the way. Try the things I told you and let me know if there is any kind of difference. This is a good one
Thanks. It was one big fuse in the fuse box which was blown up and we completely skipped it. Thanks once again
hell yeah glad to hear you got it up and working.

Reset the anti-theft. When they changed the battery, they are supposed to install a memory saving battery in the cig. lighter port so the computer doesn't have these problems.Using your key fob, lock and set the alarm, then press the unlock button twice. Sometimes that works but not on all. If it DOESN'T work, Firestone will have to pay for the dealer to reset the system. Does the car start better? Maybe you have a defective battery with a shorted cell, and the battery doesn't have the voltage for the computer to operate properly and insufficient voltage to allow the alternator to charge, setting off all kinds of low voltage problems
Testimonial: "I understand you point of view but it didnt gave me these electrical troubles for at least 10 days although the battery symbol came isntantly on. Why did electrical went bezeirk all of a sudden after so long? I tested the battery from Advance auto parts, they said battery is fine. What is your take on this now?"
Probable best guess without seeing it is a faulty diode in the alternator. Most all shops can do a diode test and check for proper charging.
