manx2day Posted August 21, 2005 Report Share Posted August 21, 2005 The thermostat might be knackered. Or it could be something to do with the fan mechanism or even the motor. If it is the thermostat, find it, cut the wires and twist them together, doing that the fan will be on permanently. Thats all i can think of.

charliechitlins Posted August 21, 2005 Report Share Posted August 21, 2005 Disconnect leads from thermostat. Start bike and connect wires. If the fan runs, you need a thermostat. If fan doesn't run, check wires for voltage (one should have it) by hooking a meter to wire and ground (or use test light, or scrape wire along ground and look for spark, or get your whole body wet and hold wire in your mouth). If no voltage, check wiring. If yes voltage, you probably need a fan. Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted August 21, 2005 Report Share Posted August 21, 2005 Permanently connecting wires is a good way to get home without overheating, but it's not a long-term (or even medium-term) fix. Quote Link to comment Share on other sites More sharing options...
coxy Posted August 21, 2005 Report Share Posted August 21, 2005 could be that your thermostat has broken and you need a new one that is what was wrong with my fan when it wasn`t workin and my bike overheated just the same Quote Link to comment Share on other sites More sharing options...
4rtbulldog Posted August 22, 2005 Report Share Posted August 22, 2005 my last experience of fan not working on my '04 model caused by low water level, refill and it works again. Quote Link to comment Share on other sites More sharing options...

manxmann Posted August 29, 2005 Author Report Share Posted August 29, 2005 well since i started this i replaced the fan motor. simple job. it worked for about a day. blagged a go in manx two day trial on sunday and after first two sections of the day the fan packed in AGAIN. its the fan motor again. can it be something else breaking them. theyre not cheap. am a bit worried about buying another motor just for it to break again. has any one experienced this?
