Buick Regal 2001 LS dashboard lights flash off and on

Regal dashboard lights start flashing off and on and needles go back and forth, warning bell dings. If I get it started, it will start doing it and shut down while driving. Braking is sporadic then. The battery was 5+ years old so I replaced it and immediately car started right up and worked fine. Turned off and restarted to check and started fine. Put tester on battery and came up with 14.7. That was last night. This morning started fine. This afternoon, back to flashing lights and dinging. Tester on battery again over 14 and put negative on battery negative and positive on alternator gave reading over 12. I have read that ignition switch could cause some of these problems or alternator. Any ideas?

It turned out the ground wire to the battery was loose, Evidently, it loosened up when driving so mimiced the earlier symptoms because it connection was sporadic. I hooked up to a computer to verify after connection tightened and it came away with no errors or problems.

    With my car, that isn't it, although when WalMart installed my new battery, they did strip out the screw on the positive post. So I had to go back and ask them to fix it, and then the alternator gave out. I figured there was some connection there, but WalMart just stonewalled it. How hard should it be to put in a new battery without stripping out the connection?? I wouldn't buy a stick of chewing gum from them anymore if I could help it.

Why wont my 99 Buick regal ls stay running it starts then immediately stalls out


Is your SECURITY light flashing? If so, you have a V.A.T.S. problem. VATS stands for Vehicle Anti Theft System. Try getting a new ignition key made because the resistance value has probably changed in the one you have. If that doesn't do it you'll need to get a VATS bypass.

2000 Buick Regal LS 3.6 - Flashing Dashboard Lights/Wont start


Most likely it is the ignition switch (the key ignition switch) in the steering column ($100 at a dealer).

It may be a loose negative battery ground cable, too.
Check the negative battery cable where it conencts to the engine ground. It may be loose, corroded, damaged, or otherwise not making a good ground contact.

Add a grounding strap ($11 - AutoZone) from the engine to the chassis. That may help, but it's most likely the ignition switch.
