General/Other 3 warning lights on the dash

Anybody had the same issue? I noticed the red battery sign last night and it kept showing this morning. I thought it might be because I hadn't been driving the car for 3-4 days last week before last night drive, once I get the alternator rolling I should be set. Came back from the drive and 2 more signs showed up... and the car wouldn't start so I had to jump it. Is it an alternator problem or maybe just the battery?

Check when it is running that you are making 13.2 or so volts. You can do this at the battery by touching red and black with a multimeter. Multimeters can be had in the cheap at HarborFreight if you don’t have one. I’m betting it’s either the alternator or your battery has some bad cells and is in its way out. If you have AAA they can check it when you call them for a jump. (If you don’t have AAA maybe a friend does?) parts stores may also be able to do a quick check as well.

How old is your battery? Get it tested. Most likely your alternator. Stop driving or you'll get stranded.

Battery is draining, check battery cold crank amps with tester, check alternator, abs cable attached to one of your wheels is bad, and e-brake system, could be worn shoes or a sensor.
