I have a 1992 Geo Prizm (same as a Toyota Corolla). The battery and alternator were replaced last March. The problem is that since then the battery and brake indicator light flashes on the dashboard intermittently. Sometimes it will come on for 2 minutes and not come on again for a month. Other times it flickers for half an hour every time I am driving. It seems a lot worse in the cold weather or when the car has been sitting for days without running. I noticed that when it does flicker on, the headlights dim slightly. What is going on? Any ideas?
Most of the time when a battery light comes on while driving it would indicate a problem with the charging system, it indicates a weak charging system. most local auto part stores will test your battery and alternator for free. you could have gotten a bad alternator or battery. The reason it flickers at times would be because of the demand on the charging system and if it is weak the indicator comes on when the demand if more that what can be supplied.
Obviously you have a short circuit somewhere. If it only started after the battery and alternator were replaced, get the person who installed them to investigate it. Why have you left it so long?
My automobile did a similar ingredient. Had the alernater examined and the guy reported it may could get replaced in a twelve months or so yet OS sturdy interior the propose time. It wasn't. It took a crap some hours later. replaced the alernater ran tremendous
