I have a 1990 Toyota Celica GT. Five months ago battery light came on and had draining of headlight power. Changed alternator (used) all was good for about two weeks. Same problem happened had alt checked and it was bad so had another alternator put in (used) ran good for two months. Now, the battery light will flicker on and off now and then when driving my car. Don't notice the lights diming yet....could I have a short or something....if so any idea how to check it...Cheap...Any ideas very much appreciated! Thank you!Need help with Toyota Celica GT....?
You can check the system for a draw on the system but if it had a draw you would have a dead battery.
First and again check the alternator again and make sure it is providing the proper amount of power.
When you say used I hope you mean refurbish. Used alternators would fail like this and the problem is your buying junk.
After testing the alternator you will need to test the battery. They can do this at the auto parts store. Your battery can be damaged from dramatic temp changes or from being drained. If its damamged it may not be getting a complete charge.
If you have a short it will take more than luck to find it and you will need to get someone who knows what they are doing.
