1996 Lincoln Town Car will not start.

An alternator would not keep a car from cranking. You could try a voltage drop test to the starter, to see if proper voltage is reaching it depending on key position. (Google "voltage drop test" for a how to.) You could also test those battery cables and cable to alternator for continuity to make sure there isn't an "open" in that circuit. You may have a fusible link in one of those cables that may have blown, creating an "open" in the starter circuit. If all that checks ok then look for a bad ignition switch. (FYI the ignition switch is not the same as an ignition lock cylinder, which is where your key goes in.)

Have u tried the "wiggle test" on the battery terminals? Try and see if u can move the negative terminal. ( and the positive terminal) If the terminals have been replaced make sure the wires going to the terminals are tight. The reason to check the negative wires to the battery is that the negative wire has to b removed to change the starter or alternator.

So I took the vehicle to the shop and they found out that one of the ground wires was totally corroded which lead to no turning over when starting and having no lights. Thanks to all the replies. I'll leave the question posted for anyone with the same issue Thanks!

HEY! CAN YOU PLEASE TELL ME WHERE THE CORODED GROUND WAS LOCATED? \UWILL TRULY BE A LIFE SAVER! THANKS! BUYERACVOUNT@GMAIL.COM
