Lately my car has barely been starting but when it does the gauge is reading 19 . It hasn’t shut off or not started , it just sounds very weak . Any one have any idea what it might be or what I should do?
Yes, you need the battery/starter/alternator/regulator/wire harness system tested.
No, I'm not going to suggest going to a PARTS STORE to do that. Any testing they'll do would be minimal, or it would be "off-the-car"; where you bring a starter or an alternator to the counter, and the counterman puts it on "The Machine" to test it.
None of that is the best way to find the problem. Neither is replacing random parts until the problem goes away, or you give up.
