I have to start my car every 3-4 days or the battery will be dead.So I'm assuming I have a phantom drain on my battery is there any that are common,and how exactley do I check for the drain?
AutoZone can check the diodes. You have to take the alternator off of the car and take it in to the store. They have a test bench that will do a better job of checking the alternator than the one they use while the alt is still in the car. I used to work at AutoZone, 5 years ago. They still have the same test bench.Greg Lawrence said:Yeah autozone checks your alternator, they say its good, there aint nuthin wrong, but they cant do a diode check i think thats it? so if the diodes are bad or something itll cause that drain problem. i remember that because they cant check something on alternators and i went round and round with them guys.
