fan switch

Postby tmcconnery » Sat May 19, 2012 10:05 am

can anyone help me figure out my fan not coming on? I can't seem to locate the fuse for the fan...all main fuses under gas tank lid test fine but none are marked fan. My fan does work when wired direct to test and my thermostat works and thermostatic switch has just been replaced. Any help would be greatly appreciated...if any one has the time to walk me through on the phone leave a number and I will call. Enjoy the weekend folks...CHEERS Trevor 1985 1200 Aspencade

If you take your seat off and look on left side along the top of the frame there is a fuse marked fan on it. I have seen it on my 84 aspy I would think that it should be the same for 85. But not sure good luck Hal

Check the voltage present at the fan connector itself, the BL/BU wire should have 12 volts, my manual shows this as supplied via the 10 amp acc fuse in the fuse block, the fuse block has the index to the fuses on a label under the fuse block lid.

I recently went through the same scenario on my 85 LTD. The relay switch, previously mentioned, on the right side of the engine was the culprit. My mechanic tells me that failure of that switch is fairly common. Of course, the radiator must be removed to change it.

Funny story, My Big brother bought a Silverwing and was done with his 84 standard so he gave it to me. It replaced my '79. For over a year the fan had quit working so he had rigged a toggle switch for it. At the time I didn't investigate so we both assumed bad wiring or bad temperature switch. When he told me he was giving it to me I obtained a full schematic for the machine. Having spent several decades working in industrial electronics as a livelihood, I wanted to get to know the machine. I noticed by the print there was a separate 1/4" AGC fuse under the seat. Yes, I removed the added switch and restored the factory wiring and renewed the blown fuse. The fan has worked perfectly in the two years hence, and I still poke fun at my big brother over missing something so obvious.
