 		 #172973 - When the Engine starts
Responding to: ???'s previous message
Erik Malund said:
... when the engine starts (12V reduced to ~6V).

On a good day!

On a really cold day, and/or with a battery that's not well charged, it could drop well below even 6V!

And, of course, on a dead battery, it could go to pretty well zero - that's when the starter just goes "click", and doesn't even try to turn the engine...
