DIAGNOSIS AND TESTING

Fuse Link Continuity Test

  1. Make certain first that battery is OK, then turn on headlamps or any accessory. If headlamps or an accessory do not operate, fuse link is probably burned out.
  1. On some vehicles there are more than two fuse links. Use same procedure as in Step 1 to test each link separately.

    To test fuse link that protects alternator, make certain that battery is OK, then check with a voltmeter for voltage at the BAT terminal of the alternator. No voltage indicates that fuse link is probably burned out.
