Last Sunday, I just purchased a 2003 Aerio SX AWD for my wife. I got it with this issue, hence a low price, but I want to ask for opinions before I start replacing parts.
The car starts sometimes, and other times it doesn’t start and just clicks over, like the solenoid doesn’t get enough power.
I got receipts from the previous owner showing a new starter, alternator, and battery all within the last 8 months. The previous owner was trying to figure out this issue, and got tired and gave up and so she sold it.
I took it down to Auto Zone for a free battery, alternator and starter test and the the person checked it with the tester, and said that the battery was overcharged, and that it was at the end of its life. Alternator tested good, but starter tested bad. When it starts, it cranks right up, no turning over multiple times before starting.
My hunch is that its the voltage regulator feeding too much power to the battery, but an overcharged battery should still allow the car to start correct?
Thanks for reading my long post and I appreciate any help you guys can give!
