This is good advice, thank you Larry.

Considering that your wires are not the culprits, you can purchase a multimeter tool to test the voltage of your battery and alternator. Turn the dial to 20, usually at the 11 o clock position. Stick it on the battery terminal and with engine off, check the voltage of the battery. Should be 13 around there if the battery has full charge and is good. Then you start your engine and you should get a reading of 14 something as your alternator is charging your battery while the engine is on. Now turn on your headlights and radio and AC and notice how the voltage is now losing little power. This means that everything is working fine.

With my car, I’m getting 13 for battery and 13.5 when the alternator is charging my battery while the engine is running. IT is barely charging the battery so my alternator needs to be replace.

That sounds like a solid case for a bad alternator. I don’t know if he’s right. Inspect the grounds in the charging system (especially the wire that runs from the battery to the alternator) to make sure those are clean and tight. If they look good, it probably is the alternator.

I had my battery tested which come back fine by a battery drop tester but then he used a multimeter and it read 13.0 slowly went up to 13.4 he said the alternator is to blame is he right ?

Sounds like you’re lucky you got it home before the battery died. It typically takes more juice to start the car than it does to keep it running. This is because the starter requires a large current, which the battery cannot deliver when the voltage has dropped too much.

Have you had the alternator tested?
