Hi lads - still trying to get used to the site so I didnt realise I had any replies, thanks. Let me be a little clearer, I can normally diagnose through standard means but I am NO electronics man I connected the fan terminals directly to a 12v battery and the fan run so I knew this was not a problem I reconnected the fan and ran the bike. Then I shorted between the 2 thermostat terminals and the fan did not cut in so I knew that even if the stat was working it still did not pull the fan on I then followed the yellow wire from the coil pack to the stat and thought "I aint messing around with the coli pack" Then i followed the wire from the other terminal on the stat which is red and it went to the regulator. I noticed that the fan wires came from the same regulator so the red must be putting power into the regulator which is activated when the stat comes on giving power to the fan Feeling brave I then unpluged the red wire from the regulator and bridged power from that to one of the fan terminals and with the bike running shorted between the stat terminals. The fan came on but I still needed to reach 85 degrees without bridging the stat to prove the stat was not at fault. It reached 80+ the fan kicked in and went off after cooling. I disconnected the direct live short to save doing any lasting damage. Sorry for the long ass explaination but thats why I am sure it must be the regulator at fault ........ I hope you can confirm it Many thanks - Matt

Hello people, thanks for having me along it's nice that there is a site for like minded people. I have been trialing now for 9 months, had plenty of thrills and too many spills already but it's a great way to hurt yourself !!! ha ha My latest issue is that my regulator seems to have stopped working. If I wire the fan directly of a 12v battery it works, if I wire the thermostat directly bypassing the regulator it cuts in at about 85 degrees and starts the fan. So I am 99% sure that it's the regulator thats at fault. Is there an alternative cheaper regulator I can fit than the Sherco one as I am strapped for cash at the moment ........... already had to repair a siezed crank 3 months ago, the piston stuck in the barrel and blew the rings 1 month ago and now it started overheating !!! Please help if you can and thanks again from a newbie
