Here is my problem, I'll try to be as complete as possible.
The car was in an accident 1 year ago with the impact on the front left of the car.
A month or so after getting the car back the battery light started coming on and slowly over a month's time came on more frequently. Electronics started flickering including head lights, dash display, dome light and got increasingly worse with time.
The battery got replaced because it was "bad" and the problem returned about a month later slowly getting worse just like the first time. This time the shop thought it was a loose ground cable, and tightened all of the cables - problem solved for about a week.
The dealer insisted after days of inspection that the cables on the battery terminals were loose and they tightened them. Problem solved for about 2 months and then same deal started over. This time the computer was outputting a "voltage spike code" says the dealer. I concluded to investigate myself before paying any more.
In playing with things I discovered that if the battery is disconnected from the system for long enough to reset everything(long enough for the radio presets to reset) the problem goes away for a week or so[/b:86138c2627] and the process starts all over, getting worse and more frequent with time.
This last symptom says to me not mechanical or electrical problem, so much as electronic problem. What do you think? Suggestions? Help?
Thank you!
