When i bought my car the battery had died an when i connected the jumper cables i did it wrong, luckily only the computer fried, or so i thought. ever since the lights would dimm when i was driving, the car starts good and runs good, ieven have a sound system in it. but i got intocars an have been learning about them and now iknow its a really bad problem. the battery is good and it never dies so im guessing the alternator is working fine, it could only the the voltage regulator,a shorted wire or i don't know what els. the computer and external fues box were replaced and the same battery is on the car. it has an indicator that sais if it has good charge or not and it says it has good charge . plaese help!
