Fuse Link Continuity Check

1. Make certain that the battery is OK, then turn on the headlamps or any other accessory. If the headlamps or accessory do not operate, the fuse link is probably burned out.
2. On some vehicles there are several fuse links. Use the same procedure as in Step 1 to test the fuse link that protects vehicle equipment.
3. To test the fuse link that protects the alternator, make certain the battery is OK. Then check with a voltmeter for voltage at the BAT terminal of the alternator. No voltage indicates that the fuse link is probably burned out.
