Additional Fuses

  • Glow Plugs and Wiring are Protected by a Special 80A Fuse Mounted Under Relay (130). 1985 diesel models differ from 1984 models by being equipped with a different Glow Plug Control Unit (P/N 1348 339 ) with an 80 Amp fuse in place of the relay.
  • On vehicles equipped with Anti-Lock Brakes (ABS), the system is protected by (2) additional fuses. (1) 10 Amp fuse located in the trunk compartment on the right side, and (1) 80 Amp fuse located on the left inner fender.
  • '88-'92: The ABS system is protected by an additional 10 AMP fuse which is incorporated in the surge protector at the brake pedal mounting.
  • '88-91 (780): The system also includes a 10 A fuse for the ABS (anti-lock braking system) function. This is incorporated in the transient surge protector at the pedal mounting.
  • '89-91 (780): At battery - Two 30 A fuses for front/rear amplifiers (not Italy)
  • '89-91 (780): At left suspension tower - One 10 A fuse for High-output turbo system (B230FT)
