Hi, my battery light has come on three times now. The first time it was my alternator which I replaced, the second time it was the alternators attachment cord to the battery (it had been burnt through-possibly from shifting in the engine as my motor mount was bad) replaced the mount and the alternator. But now it has come on again! I have no idea what it could be, there is no odd noises, smells, it runs fine. I’ve replaced almost everything I can think of in the last 2 years. ---

You need to take it to as shop that does proper electrical troubleshooting. This piecemeal bit is a hit and miss affair and will nealrly always cost you more than solving the ACTUAL problem. Since neither you or I know what the problem could be, have the shop analyze the electrical system. A chain that does brakes and mufflers, or sells tires, is not the place to go. How did you know you really needed an alternator? ---

The first time it was obvious, there was a code I believe and they checked the battery. The battery was fine, so they checked it after attaching a new alternator and the car worked. The second time, they went under the hood and found the wiring was burnt about 85% through. They tried it with a new alternator (after I had the battery replaced and checked) and it worked great. Now that the light has come on again, I don’t know what the problem could be…unless the cord burnt again. But why would that happen? ---

We don’t know what make model or year car. I also not sure about that light. Is it a “Battery” light or is it a CEL (Check Engine Light)? If CEL you need to have someone check the code that will be stored, if it is a battery light then you need to have the battery and alternator checked. Most auto part stores will check that for free. Don’t assume that a rebuilt alternator good. Many are not properly rebuilt and don’t last long. Good Luck.
