Possible Starter relay failing? (if its setup like the Cascadia)... watch your voltage when you hear the click with no start --- does it drop ?

- I replaced my starter a few weeks back because it had been weak for awhile and drawing a load of amperage while cranking. Before it was replaced, it would def click a few times on many of the attempted start cycles before actually rolling over. That starter had about 440k miles of starts, so needless to say, it's earned its keep lol.

Whats the age of the starter? New or reman? Check how far the starter pulls down the voltage while cranking. That's a good way to see if it's getting weak.
