I installed a new battery yesterday. Moved my car and parked it. Well today I tried to start it but I didn't start. The blinking security light came on but was dim, the ligths on the doors were on but dim..and the clock came on but that wasn't dim. Well I looked at the terminals and they don't look bad..tightend them up too. I tried to start it again tonight but still wouldn't start. When I tried it the first time today, nothing on the digital dash came up like the speeed and tach but the clock, security light and lights and door came on. After I tried it tonight. Nothing came on, so I wiggled the terminals again and tried again. The clock slowly came on but when I tried to crank it over, the clock went blank. Do you think its the alternator belt or something like that?
