Hey guys this is the second time this has happened that iv known about and this time It left me stranded. But my bikes radiation fan will sometimes turn on even when the bike is off. I went into work and come out 8 hours later and I hear the fan spinning and my battery was dead. Lucky I found some one to jump me off. But I thought I could be a relay but it doesn't do it all the time and the fan still works when the temp gets high. I didn't notice it turn on right after I got off so not sure if it's just random or what. Any help would be great thanks.
