[QUOTE="Sunnyorlando, post: 1456207, member: 92915"] No, it's the other way. This bad switch is internally shorted, it tells the relay that the sidetand is [B]up[/B] all the time and that's why it starts with sidestand down under any condition, because it doesn't know. So this is a 'N/C' circuit for normal operation - run. Shorted means sidestand up. Then when OPEN ([I]or unplugged[/I]), it knows that the stand is down. When the stand is UP, the circuit closes and allows the bike to start - and that's where this switch is stuck in, closed circuit. [/QUOTE]
