Car won't start, battery and alternator replaced

What is your question?

My husband replaced the battery and alternator on a 1995 Ford Thunderbird. It will not start, no lights come on in the dash and there is no kind of sound at all. He also checked the fuses, all of them good. We are wanting to find out what else to check for; if it's electrical or what.

How long has your 1995 Ford Thunderbird had this problem?

Almost 2 weeks
