FUSES AND CIRCUIT BREAKERS | |
The headlamp circuit is protected by a circuit
breaker in the light switch. An overload on the breaker will
cause the lamps to "flicker" on and off. If this condition
develops, have your headlamp wiring checked immediately. Also,
a special circuit breaker, mounted on the firewall, protects
the power window, power seat, and power top circuits if vehicle
is so equipped. Where current load is too heavy, the circuit
breaker intermittently opens and closes protecting the circuit
until the cause is found and eliminated. Fuses, located in the Junction Block beneath the dash are: |
|
Radio, TCS, Rear Defogger, Hydra-matic Downshift | 10 Amp. |
W/S Wiper | 25 Amp. |
Stop Lamps, Hazard Flasher | 20 Amp. |
Heater, A/C | 25 Amp. |
Directional Signal, Backup Lamps, Cruise Master, Side Marker Lamps, Blocking Relay (A/C) | 20 Amp. |
Instrument Lamps, Floor Shift Lamps | 04 Amp. |
Gauges, Instrument Panel Warning | 10 Amp. |
Clock, Courtesy Light, Lighter, And Diesel Control Decklid Lock, Glove Box and Dome Lamp | 25 Amp. |
Tail Lamps, License, and Side Marking Lamp | 20 Amp. |
An Air Conditioning high blower speed fuse, 30 amp. is located in an in-line fuse holder running from horn relay to Air Conditioning relay.
Fusible Links are incorporated into the wiring system. These are wires of such a gauge that they will fuse (or melt) before damage occurs to an entire wiring harness in the event of an electrical overload.
