Truck won't start in cold, have a new battery

[ben_cline]

My truck won't start when it gets around 40 degrees or especially colder. I bought a new battery, and I still have trouble starting it, no better than before. It will crank slowly for 10-20 seconds before it will start some days. On a severely cold day, it just makes a low grinding noise and dies. If I drop the clutch, it will start in a half of a second. I'm not sure if it's the starter, or something else.

The most likely cause for this, having eliminated the battery as a suspect, is your terminals, cables, and connections.

Inspect both the positive and negative main cables and ends, between the battery, solenoid, starter, and engine/frame ground. Make sure everything is clean, tight, and undamaged. Make sure the grounding points are tightly connected to clean, bare steel (rust is a very poor conductor of electricity).

Check the cables running out the back of the battery terminal connectors; they tend to fray and break there.

The connections on the battery seem good. I charged the battery to 611 CCA, according to Walmart, and not strong enough to start it. It would start when I popped the clutch. If I jump it, it needs about 2-5 minutes to charge up.

And what about the connections to the solenoid, starter, and grounds, as specified above? And the condition of the wires all the way from end to end?
