I don't mean to butt in here, but the easiest way to test for continuity is with a continuity tester. Buy one at your parts supply house. They are cheap. If it lights up when you touch the probes to the terminals there is continuity. No light, no continuity. Make sure you pull the electrical connectors off of the fuse or thermostat before testing so you don't get a false reading. Some say it doesn't make any difference, some say it does. Take them off anyways.
