gasgasssser Posted July 8, 2007 Report Share Posted July 8, 2007 Are you sure it didnt come on?after 2 hours without the fan,the bike would have boiled over or even worse,siezed up.Are you at the north pole ?? Quote Link to comment Share on other sites More sharing options...
copemech Posted July 8, 2007 Report Share Posted July 8, 2007 first check the coolant level, the thermo switch for the fan will not work without coolant in the ststem. The fan normally cycles after about 5 min. running from cold (around 180f water temp i think) . If it does not come on, disconnect thermo switch and connect wires together, start the motor and the fan should run. This is only a temp fix! If it still does not run, you have problems!

brian r Posted July 9, 2007 Report Share Posted July 9, 2007 Try to jump start the fan by flicking the blades with your finger once it's warmed up. Quote Link to comment Share on other sites More sharing options...
jezzaxt Posted July 12, 2007 Report Share Posted July 12, 2007 Or stick a 12 v battery charger direct to the fan. That way you'll bypass everything and know if it's just the fan motor that's had it. No panic if it is. Sherco ones tend to be quite expensive so I stuck a gas gas one on mine for half the price. Just had to extend the wires slightly. Good luck Quote Link to comment Share on other sites More sharing options...
