Fuse Links

A fuse link:

• Is a short length of insulated wire, integral with the engine control sensor wiring (12A581) .
• Is several wire gauges smaller than the circuit which it protects.
• Is generally located in-line directly from the positive terminal of the battery (10653)

NOTE: Replacement fuse link color-coding may vary from production fuse link color-coding.

Production fuse links are color-coded:

• 12-gauge: GY
• 14-gauge: DG
• 16-gauge: BK
• 18-gauge: BR
• 20-gauge: DB

• When heavy current flows, such as when a booster battery is connected incorrectly or when a short to ground occurs in the wiring harness, the fuse link burns out and protects the generator (GEN) (10346) or wiring.
• A burned-out fuse link may have bare wire ends protruding from the insulation or it may have only expanded or bubbled insulation with illegible identification. When it is hard to determine if the fuse link is burned out, perform the continuity test.
