When I turn on the key in preparation to start my K100RS, some of the instrument lights illuminate. I see the brake failure warning triangle, the neutral indicator, perhaps the "choke" and battery but the temperature warning light never lights. Does this only light when the engine runs too hot? Does this mean I have a bulb failure? I don't ever recall seeing this light, even when I ride the motorcycle in high ambient temperatures. I do note the fan turns easily when I spin it manually, but I'm wondering if there is a faulty relay or some other glitch.
With any luck, I'm worrying unnecessarily.

This bulb doesn`t turn on with the ignition, no worries, sleep thight

dont think i ever saw mine come on brickrider .....till i installed a manual fan (temp sensor shorting ) switch

Mine only comes on when the fan kicks in, its only happened a couple of times... when doing what we British do best......queuing.

The warning lamp should normaly show later.............

The fan kicks in at 103^oC, the warning lamp should show up at 111^oC.
