Hardwiring Fan - 5/16/2008 11:59:14 AM    drtoohotty   Posts: 6 Joined: 3/23/2008 Status: offline Hi guys ok so here’s my problem I just got my first bike an 03 F4i took it for the first ride the other day and found the radiator fan didn’t turn on at 104 C so I brought it back and checked the fuse sure enough it was blown, replaced it and thought everything was fine went for another test ride and same thing no fan, came back again and checked the fuse again to my surprise also blown so I have a short I want to make a temporary fix so I found this method "just unplug the sender cable then make a wire up with 1 ring crimp and 1 spade crimp, put spade crimp in the sender wire plug and then put the ring crimp on the ground for the radiator fan, which is literally just above the fan on the radiator... takes 2 minutes to do, you can get to everything, don't need to chop anything!! And the fan will come on with the ignition" my question is, is the sender cable the connector above the oil cooler water hose or the connector just above the lower rad hose? Im not very well versed in electrics so the simplest explanation would be the best. Thanks in advance. Post #: 1

RE: Hardwiring Fan - 5/16/2008 3:38:33 PM    Big Gaz Posts: 36 Joined: 4/13/2007 Status: offline i'd start from the sender unit and chase the wire back up to the blowing fuse. your looking for cuts in the wires that might touch the frame or any metal at all. that would cause the wire to go to ground, short  and in turn blow the fuse. also it may be worth check the sender itself, it maybe an internal fault to the sender itself. If is easier chase the wire from the fuse down. It will take time but if you quick fix it you will still have to eventually troubleshoot the origional fault. _____________________________ 06 F4i Airblade Iridium Screen PC3 Jardine RT-1 High Mount Undertail (in reply to drtoohotty) Post #: 4

A bit expensive, I would look up the part there, and then go get it somewhere else if you can find it. _____________________________ (in reply to drtoohotty) Post #: 6

I wouldn't even try to connect it.  You've been given a warning.  Thing to do is find the short -  end of story. _____________________________ red/silver '05 F4i Akarapovic slip on; Vortex sliders; mirror extenders Rich's custom leather seat; Scorpio alarm Kisan pathBlazer headlight modulator Whistler Cruisader radar detector (in reply to travsstuff) Post #: 8
