Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,If you are not seeing any light and everything is dead then I would agree with your husband and start with having the battery checked to be sure its properly charged and the connections are clean and tight. All power start with the battery. In order for it to start the car you need at least 12 volts to it. Have him remove it and run it down to your local part store and they will test it at no charge . Check this and let me know if you have more questions and or need more help and we can work from there.
