Could throttle cable be the culprit?

Here's what's going on;

I'm getting nothing to the starter. I replaced the starter yesterday. Shifter is in "neutral" position (I have had some issues with it in the past in trying to find that "sweet spot" in order for it to start). Battery is ok. Reset button doesn't appear to be the issue. I do see a draw on the volt gauge when I turn the key completely over as if attempting to start. Where should I begin to look first? Any suggestions or comments would be appreciated.

Check the neutral switch in control if its working OK with tester. Then check the starter relay unit on engine and I suspect this is your problem.
