Do a voltage drop test on the battery cables. Assuming battery is good

How would I do that? The battery is new replaced it when my alternator went out a month or so ago
Look up on YouTube. ChrisFix has good video on this titled. “How to test an alternator”. There are many on here watch a few and see if your wiring is good. He also shows how to load test your battery. You might have a bad battery?
This video also pinpoints bad connections

I will check out the videos may be I can find something on there ive looked at thousands of YouTube videos and have been trying everything. My alternator and. Battery are brand new. Plus I have a battery reader on my truck. Plus my truck wouldn't jump start from the starter is my battery or my alternator was bad. My next step is the ignition switch.

I've been driving My vehicle for 2 weeks with no problems other then it doesn't crank over but I can start it from my starter
Another good video is starter voltage drop testing by TCAT Autotech.
Have you tried putting truck in neutral and trying to start it? Bad safety neutral switch.
