Start by turning on the head lights. The current that may be trying to flow will insure the bad connection will show up during the following tests. If you're using a voltmeter, put it on the 20 volt DC scale. You're looking for a reading near 12.6 volts. If you're using a test light, you're just looking for a bright light.
I'll assume you're using a voltmeter but if you have a test light, just use the clip lead as one probe and the point as the other one. Put one probe on each battery post. You should see 12 volts or a bright light. Move one probe from the negative post to the battery cable connected to that post, then move the positive one from the post to the cable. Move the negative probe to the end of the small black wire that bolts to the body sheet metal. The probe has to be on a clean bolt anywhere on the body, or a paint-free surface. Move the positive probe to the fuse box under the hood. There should be a red cable bolted to it. Put the probe on the terminal, then on the stud. You're looking for the first place where you no longer have 12 volts or the test light doesn't light up or is dim.
Holler back with your findings.
