2000 Cadillac Catera Q&A
2000 Cadillac Catera Question: charging system
The inputs to the alternator should be checked for proper voltage signal. You may need a qualified technician to look at the charging system on your 2000 Cadillac Catera to correctly diagnose your problem. - Russ
If the battery voltage gets down to around 9 volts or less the car may not run. The electrical system must have 9 volts or more to operate correctly. You probably need to get someone to test the alternator and charging system. You may very well have a new bad alternator - ProChevy
The radio has no sound. The batt. went dead and had to charge it, and then this started to happen. Check the fuses under the drivers side. Is there more? or a amp fuse?
