1999 Cadillac Seville SLS Q&A
1999 Cadillac Seville SLS Question: I was told my car was not starting because it needed a brand new alternator.
There are many causes that may cause car don't start: Low battery; Loose or corroded battery cables; Bad starter relay wiring connections or ground connection; Bad starter relay/solenoid; Bad starter; Damaged starter drive or teeth on flywheel; Bad ignition switch; Engine seized due to bearing failure or internal damage; Engine hydrolocked due to coolant leak from leaky head gasket I suppose to eliminate and check those causes one by one. Good luck. - chinasinoy
Your car does not need an alternator to start. Whoever told you to put an alternator in to fix it should not be trusted. - dale45
my car had the starter changed and Pep Boys put a hole in my transmission which caused fluids to leak where they weren't supposed. - YaeOh
My '97 Seville had that problem after I replaced the alternator. Everything was working fine beforehand except the panel said, "battery not charging" The replacement is not for everyone but I managed. The car tried to start, then all lights when out -- the car was dead, nothing worked. I removed and checked the alternator assuming it had a short, charged the battery; both checked GOOD. After checking fuses, solenoids, alternator wiring and anything else I could think of, I hooked my meter to the battery, had my wife attempt to start the car, and the battery went to 8 volts and then to 11.5 V. I took the 1-year-old battery back and after checking it, they warrantied a new battery. One for the books, very dependable now. - Jack Reechre
