Good Day Gentlemen,

My next task is to debug the coolant temperature circuit. I was wondering if I should see some type of movement of the needle at all when I turn the key over, whether the boat is cool or hot? Will it move a hair to indicate power on? Seems dead. Is there an easy way to debug this, besides running the boat until it gets hot? What is more likely to go, the sender or the gauge?

Thanks - Steve
