Default Re: reverse polarity
I just bought the Crossfire a month ago and it has a MOPAR H7 from 2011. When it needs replacement, I'll go to an AGM but see no need before then.

If having a starting issue I'd connect a voltmeter to the big starter connection and crank. If it goes under 9-10v and cranks slow it is one of three things:
1) Bad battery (can check with a load meter.(Mostly use one of these ).
2) Bad wiring - will see a drop between the battery terminals and the starter - will generally get hot after a few seconds creaking - can spot with an IR meter)
3) Bad starter - pulling too much current.

However what I said earlier still stands, the lower compression should make a SRT easier to crank than a N/A, not harder.
