Fusible links
Fusible links are designed to protect a circuit under high current overloads. Links are used in high-current circuits that cannot be protected by a conventional fuse.
The FJ80 vehicles have cassette type jumpers, while the FJ60 and 62 vehicles have soldered jumpers.
Cassette type jumpers look like fuses. Some cassette jumpers are additionally secured with a screw.
Soldered jumpers cannot be repaired. To replace such jumpers, do the following:
- disconnect the battery from ground;
- cut the jumper right on the connector;
- remove the insulation from the end of the wire at a section of about 13 mm;
- secure the connector to the jumper by crimping the connector tabs and solder the connection with rosin-based solder;
- seal the joint securely with tape;
- connect the battery to ground and check the operation of this section of the circuit.
Circuit breakers
These devices protect the electric circuits of the window lifter, door locks and headlights.
On some vehicles, when the circuit is overloaded, the circuit breakers are triggered automatically and immediately close, the circuit is restored. If the circuit is not restored after the circuit breaker is triggered, then an immediate check of the circuit breaker and circuit is required.
After the fault is eliminated, the circuit breaker state is restored automatically. Some circuit breakers are closed after they are triggered manually.
