History
Coming back from a client on Thursday I had to ride through the city. It was hot as hell and just when I was about through I noticed that my temp gauge was right in the red. I pulled off immediately and waited for the engine to cool off. The bike had water in, but the fan was not working.
I did the test of pulling the wire out of the meter on the radiator and connecting it to earth â?? but got nothing. Having given the bike time to cool down I rode it home, keeping a close eye on the temp.
At home I first tested the fan with a direct supply of 12V, the fan is ok. I then took off the right hand shroud and checked the glass fuse. No problems there â?? the fuse was ok.
Ok start stripping the bike down and try to find if one of the wiring looms is damaged â?? but all is ok. Here I ran out of time because I have work to do, so I only continued this afternoon â?? two days without bike
This afternoon I print the wiring diagram and start tracing the wires, landing up at the fan relay switch. This little unit looks expensive, so Iâ??m not happy. Iâ??m bugged though, these units are usually robust and donâ??t go haywire often.
I decide to have another look at the wires, but this time I check the fuse with the AVO meter while itâ??s still inline. Nada â?? the fuse is a complete disconnect.
I take the fuse out (first time I actually take it out) and immediately see the green corrosion between the fuse and the clip that it clips into. Clean off both the fuse and the clip and plug everything back, and voila! The fan comes on when the switch wire is earthed!
Iâ??m so happy, I could drink a beer! Iâ??ll have a few later.
Ok the lesson here is that visual inspection does not always give the answer â?? especially not in electrical problems. Electrical problems is notorious for being difficult to find â?? but if you are going to go after one, use a meter!
Hereâ??s a pic. Itâ??s not very visible, but Iâ??ve encircled the green corrosion mark. Keep this in mind, because itâ??s something that wonâ??t be picked up during a regular service. Mine probably came about because I park my bike outside and I ride in the rain.
Happy maintenance dudes!
