Book Excerpt: 1987-2007 Honda XL600 Transalp, XRV750 Africa Twin Repair Manual COOLING SYSTEM

COOLING FAN AND FAN SWITCH | CHECK AND REPLACEMENT COOLING FAN: CHECK

1. If the engine is overheating and the cooling fan isn't coming on, first check the cooling fan circuit fuse (see Chapter 9). If the fuse is good, check the fan switch as described below.
2. If the fan does not come on (and the fan switch is good), the fault lies in either the cooling fan motor or the relevant wiring. Test all the wiring and connections as described in Chapter 9, following the relevant Wiring Diagram. Disconnect the fan wiring connector and check that there is battery voltage at the black/blue or blue/black (according to model) wire terminal on the loom side of the connector with the ignition ON. If there is no voltage, check the wiring.
3. To test the cooling fan motor, on XL 600V and XRV750 models remove the right-hand fairing side panel, and on XL650V models remove the fairing (see Chapter 8). Disconnect the fan wiring connector and the fan switch wiring connector (see illustrations). Using a 12 volt battery and two jumper wires with suitable connectors, connect the battery positive (+) lead to the black/blue or blue/black (according to model) wire terminal on the fan side of the wiring connector, and the battery negative (-) lead to the fan switch wiring connector. Once connected the fan should operate. If it does not, and the wiring is all good, then the fan motor is faulty. Individual components are available for the fan assembly.
COOLING FAN: REPLACEMENT WARNING: The engine must be completely cool before carrying out this procedure.
4. Remove the right-hand radiator (see Section 6).
5. Disconnect the wiring connector from the fan switch (see illustration). Free the wiring from any clips.
6. Undo the bolts securing the fan assembly to the radiator, noting that one of them also secures the ground wire (see illustration).

ELECTRICAL SYSTEM

HEADLIGHT

2. If a headlight beam fails to work, first check the fuse (see Section 5), and then the bulb(s) (see Section 7). If they are good, use jumper wires to connect the bulb in question directly to the battery terminals. If the light comes on, the problem lies in the wiring or connectors, the switches in the circuit, or the relay(s) (XRV750 models). Alternatively the bulb can be checked for continuity using a multimeter. Refer to Section 20 for the switch testing procedures, and also to the wiring diagrams at the end of this Chapter.
3. On UK and some European XRV750 models, a relay controls each of the headlight circuits, i.e. one for HI beam, one for LO beam. On other European models XRV750 models, there is a HI beam relay only. Refer to the relevant Wiring Diagram at the end of the Chapter for your model, or simply remove the fairing (see Chapter 8) and check to see whether there are two relays or one for the headlights. If a beam does not work and the relay is suspected of being faulty, the easiest way to tell is to substitute it with the other one (twin relay models) or another one (single relay models) if available. Remove the fairing to access the relay(s) (see illustrations). If the beam then works, the faulty relay must be replaced with a new one.
