Fuses

Print

See Figures 1, 2 and 3

All electrical equipment is protected from overloading by fuses. Each fuse has an amperage rating that will allow it to transmit a predetermined amount of current before its filament melts, thereby stopping the excessive current flow. By providing this engineered weak spot in the circuit, the first failure will occur at a known location (the fuse), eliminating hours of tracing wiring harnesses to locate a problem.

If a fuse blows repeatedly, the trouble is probably in the electrical component that the fuse protects. NEVER replace a fuse with another of a higher ampere rating. Sometimes a fuse will blow when all of the electrical equipment protected by the fuse is operating, especially under severe weather conditions. For this reason, it is wise to carry a few spare fuses of each type in the car.

When tracking down an inoperative electrical circuit, follow a logical pattern. Wiring itself is rarely the problem. Remember that, in some cases, a fuse can look good but not be capable of passing an electrical load. Either remove the fuse and check it with an ohmmeter or simply replace it with a new one. Always have the ignition switched OFF when removing and replacing fuses. On all models, the circuit that each fuse protects is listed either on the fuse box cover or in the owners manual.

A blown fuse is indicated by the failure of all units protected by it. It is caused by overloading the circuits. Examine the curved metal wire, on the inside of the fuse, to see if it is broken. If so, replace with a new fuse of the same color and amperage.

REPLACEMENT



240 and Coupe Models

The fuses and relays on 240 and Coupe models are positioned in the front of the left front door pillar. When installing fuse No. 1, be certain to use an 8 amp fuse.

Fuses and relays on the 760, 780 and 940 models are located in the central electrical unit behind the ashtray in the center console. In addition, a fuse for the ABS braking system is located under the instrument panel, to the left of the steering wheel. When installing fuse No. 5, be certain to use a 15 amp fuse.

Fuses and relays on 740, 850, 960 and all 1998 models are located on the far left side of the dashboard. When installing fuses No. 26 and 33, be certain to use 10 amp fuses.

All vehicles are equipped with a fuse removal tool, located in the fuse box. Grasp the blown fuse with the tool and remove it.

Care must be exercised when replacing fuses. Check to ensure that the ignition switch is OFF.

700 Series and 940 Models
  1. To obtain access to the central electrical unit, remove the ashtray. Pull out and depress the tongue.
