Greetings,
When I turn on the ignition before starting the engine on my '95 K75 the oil pressure and the charging lights on the Tachometer come on and go off when the engine starts up. However, the temperature light never comes on. Is that normal? Recently I experienced a coolant leak and the fan came on . One would think this would be a good time for the temp light to light up but it did not. Somehow I cannot believe that this a case of a burned out bulb.
Any advice or comments are greatly appreciated.

One might think that, but one would be incorrect. In an engine running appropriately, the fan comes on to regulate coolant temperature. That is usually in stop-and-go traffic/hot weather or if the coolant level is too low. That's normal. The temperature light comes on when the fan is unable to regulate coolant temperature. When that happens, the rider should stop, check for leaks, check the coolant level in the reservoir then let the engine cool down before proceeding.
Where's the coolant leaking?

Before you start the bike:
There's no oil pressure - light on
Alternator not spinning or generating current - light on
Engine coolant below 232 degrees - light off
The fan comes on at 217 degrees to keep the coolant from getting up to 232 degrees when the temp light illuminates.

Thanks for your reply.however, it does not answer my question. When I turn the key and turn the ignition on BEFORE starting the engine the alternator and oil pressure warning lights come on. I guess as a bulb test. However, the coolant temperature light dos NOT come on. All want to know is if "normally" this light should come on too.
Please advise and thank you.

Reread my post: Before the bike is started the temp is below 232 so the light does not come on.
