Detail: I replaced the battery in my 2003 Acura TL a month ago. I had no problems with it until last week when it wouldn't start; after a few minutes it started and again, no problems until yesterday. Now when I try to start it all I hear is a single click.
Solution: I suspect the problem lies in your starter. When a battery goes bad, it can cause surges that can adversely affect the rest of the electrical system, causing different components to go bad. If you've done a load test on your battery and it is functioning correctly, then you'll need to have the starter tested and / or replaced. The single click implies the solenoid is working correctly but the armature in the starter is not turning. If your starter is expensive, you may be able to have a mechanic replace the armature in your starter. If you choose this option, have the mechanic replace the brushes in the starter as well. , Hi, a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.
