Recently I have this annoying problem. Only when wet and damp out does this happen. Start engine cold, after a few seconds alarms starts to sound, sometimes scratchy like a poor connection. When really wet & damp sound is solid. Turn engine off and just key power on, same noise. After a dry day all gauges clear no dampness, sound goes away, might stay off for a week or two if no moisture. Checked small oil tank seems fine, played with float, seems fine. My guess is, the over temp alarm is grounding out some where when damp. Where is this? How many on a V-6 ? I’m assuming that’s how the OT alarm works, when closed to ground will close circuit and cause alarm to sound, I could be all wet. Any idea’s greatly appreciated?<br /><br />1997 Yamaha 250
