Ok so, I bought a solenoid from O'Reillys for $20, installed it and BOOM, she cranks right up!!! Battery still seems too weak on cold mornings. Looking for a good one, any ideas on Amps/CCA? Manual states 30 Starting amps with 340 CCA.
Before buting a new battery which is likely needed, run a voltage drop test while trying to start.
Put test lead on battery post (not the clamp) and to stud at starter. If more than 0.5 volts interrogate where the voltage drop occurred and fix. Also do for the ground side. Many good videos on how to do this on YouTube. This test the circuit under load which can be very telling.
