Hemi 5.7
A couple of days ago I stopped to put gas in my 2006 1500 5.7L hemi
Went to go start it and it didn’t
It cranked but wouldn’t turn over
It was -29c with the wind chill so I figured that was the issue

Had to leave it overnight and try and figure out the issue

Tried to boost it the next day, on the gauge it shows it was barely registering maybe around 5-7 volts
So I went to get a bee battery
I got a MagnaCharge battery with 850 cold cranking amps
1100 cranking amps
40 months of warranty, only $175 CAD wicked deal

Anyway, replaced the battery and it started! Couldn’t believe it was so easy!!
Turned it off again and it started
So finally got to drive it home, took about 2 1/2 hours, it drove great the entire way
Shut it off after I got home, triumphantly

Then after about 10 minutes went to start it again, wouldn’t start, showing below voltage again
Tried to boost it and it went to maybe about 9-10 volts
Went I went to crank it then voltage went down!

I know if it’s still not boosting it can’t be the alternator
Checked the starter relay
Can’t figure out why it won’t start this time

Check your battery cables and main electrical ground.

Check your battery cables and main electrical ground.

^^ This ^^ Follow the cables all the way end to end. Also, if you do get it started again, put a meter across the terminals and look for 14ish volts to absolutely confirm your charging system is putting out enough.

The electrical system grounds to the frame so it's the cable from the negative side to the frame.

If the ground is good, then check the cable for continuity across it's length. Basically see if it will pass voltage from one end to the other.
