carpb202 Posted October 3, 2017 Share Posted October 3, 2017 Hey y'all! I recently had to replace my clutch cable due to stretching and since then, my fan fuse has blown twice. I replaced the first one, then it blew again this morning, and proceeded to overheat in traffic. So I've got a couple questions: 1) How can I find where this short is happening that's causing the fuse to blow? 2) Can I put water in the coolant tank? Thanks!

carpb202 Posted October 3, 2017 Author Share Posted October 3, 2017 I'm not sure. Everything is packed in so tightly that I can't really see anything that's going on. I might need to take off the right-side fairing to get a better look. Link to comment Share on other sites More sharing options...
BBB Posted October 3, 2017 Share Posted October 3, 2017 Sounds like you nicked a wire when dragging the clutch cable through, so examine the route you took. A bit of electrical tape over any exposed wires will do as a temporary fix. You can top up the coolant by the bottom of the right fairing. As winter is approaching, make sure you use a suitable antifreeze mix. Red 2015 Tracer, UK spec (well, it was until I started messing with it...)

carpb202 Posted October 3, 2017 Author Share Posted October 3, 2017 I've got a feeling you're right @bbb Is there any trick to checking the wiring besides taking the fairings off? Even with them off, I don't see a way I can really get in and inspect the route. The only side that would be affected would be the left (as sitting on the bike). Do you know any wiring that goes on that side? ...and now that I'm looking at it, I think the fan wiring goes by the seat. That's the next thing I'll check as I wouldn't doubt if I somehow rubbed a wire trying to put the seat back on. Thanks! Link to comment Share on other sites More sharing options...
Buggy Nate Posted October 4, 2017 Share Posted October 4, 2017 Just take the fairings off and have a good look mate, and while you have them off make sure an errant rock hasn't got jammed in the fans blades. That was the number one cause for blown fan fuses when I was spannering. Link to comment Share on other sites More sharing options...

skipperT Posted October 4, 2017 Share Posted October 4, 2017 I've got a feeling you're right @bbb ***snip*** ...and now that I'm looking at it, I think the fan wiring goes by the seat. That's the next thing I'll check as I wouldn't doubt if I somehow rubbed a wire trying to put the seat back on. Thanks! The fan wire harness with a 2P plug does NOT run near the battery. It plugs into the main harness on (I think RH, but could be left) side of the neck of the frame. I pulled the radiator/fan away for my valve adjustment a few weeks back and I’m 90% certain I unplugged the fan from the front. Checking for a rock is much easier and great suggestion. -Skip Link to comment Share on other sites More sharing options...
carpb202 Posted October 18, 2017 Author Share Posted October 18, 2017 I've got an update for y'all! Was able to take a hard look at the bike over the weekend and found that in my initial clutch cable routing, it was rubbing against the fan, causing it to spin very hard. I was able to re-route the cable verifying that the fan can spin freely, and replaced the fuse. However, the fuse still blew It was suggested to see if the fan motor burned out. Is this as simple as connecting a 9V battery to the plug? Link to comment Share on other sites More sharing options...
skipperT Posted October 19, 2017 Share Posted October 19, 2017 Yikes. Sorry to hear the news. Not sure why the fuse still blew, but you won’t like the answer. You can connect a 12v (not 9) directly to the fan connector and see if it spins freely. Did you replace the fuse with one that’s the same size? The fan pulls quite a bit of current when it starts up. If the answer is yes, then the fan is probably damaged and pulling more amps when it is spinning then the circuit is designed for, which is why you are blowing the fuse still. The only real way to test this is to measure the amp draw of the fan when it is first connected and begins to spin. You need an inductive amp attachment for a DVOM. Then compare that value to a known good fan to see if it’s excessive. Yamaha doesn’t publish a spec for the fan. Probably easier to jump it with a 12v battery (preferably NOT one from a car) and see how it sounds. If it doesn’t sound the way that it used to - replace the fan. Make sure your sitting down when they quote the price to you. -Skip Link to comment Share on other sites More sharing options...
