2009 Vector is 50/50 on starting

[Brenden]

Hello, I have a 2009 vector ltx gt and I've been looking everywhere to see if this is an already diagnosed problem. Last week it was -33 to -37 Celsius for 3 days in a row, which I did not start my machine. The one day (-35) I had plugged in the block heater and let it sit for an hour before attempting to start it, turned the key and all I got was a click. Tried multiple times in the next day trying with and without the block heater, still just a click when turning the key. Took it to our heated shop and let it sit a day to thaw out. Turned the key, started like nothing. Brought it home after installing some new powder hound skis, and all was fine. Plugged it in before working later that same day, tried starting it, and all there was, a click. 10 minutes later when I was about to walk, figured to try it one more time, it turned over perfectly, not plugged in. When in a heated or semi-warm indoor place, starts with no issue. In the cold it's 50/50 between getting a click. Weak spot on the starter? Battery issue? Does this sound familiar to anyone?

It hasn't warmed up from the -30's here so I can't see if it will start fine if it's warmer or what is even up with it!

Check the battery connection and the relay by the battery.

as mrsled said first. might be the solenoid is getting bad too. I do know that a freind of ours with a 2010 venture need3ed to use a boost pack every time he started his sled at those temps as it would just not turn fast enough even with synthetic oil in it. meanwhile the 05 war would fire right up after 45-60 seconds of cranking in same conditions.
