Wait to start (Grid Heater)

[Stomp]

I know if it is cold I usually wait for the light to go off, but some days it does not seem that cold so even if the grid heater comes on I don't wait is that bad. At the ranch we have 4CTD's 2 first gens and 2 2nd gens, no one ever waits for the light no matter what the temp is outside. They all seem to start right up.

Usually if I hear the gird heater click on I wait for the light. Sometimes I wonder why it clicks on because it isn't that cold.

When the pickup is worm then I never wait for the light, so if someone can enlighten me on the subject it will be much appreciated.
