‘95 f-150 start problem
Over the past two weeks my truck started to need to be jump started occasionally. Everything was dead not even the dome light would come on. New battery and just had it load tested, alternator gave good voltage while running. Volt gauge would get shaky so I just replaced the regulator and now the truck will only run off jump cables with another car. As soon as they come off the truck dies.
Any thoughts? This is my daily driver so I need to figure something out quick! Thanks in advance.

Sounds like either your battery is dead(you need battery power to fire the ignition) or you have a bad ground.

I had the battery tested today at autozone and they said it was good. Later in the afternoon I did my own load test and found that the battery has 100 cca instead of the 850 it’s supp to. So put a new battery in and gonna throw a new alternator on just to be safe but she’s running again 🙄

Take a meter and check as follows:
On volts ( low scale if you have to select) check between the ground terminal on the battery and the actual cable end terminal.
If you get any significant reading at all you have a bad connection. Chances are that one will be ok, if not, remove it and clean it.
Start checking back from there to all the ground connections from there out. Bad connections will show up as a voltage. Make sure they are all clean and tight.
Remove and clean all of your connections that show as bad.
Check the positive cable the same way.
Don't forget Cables can be corroding internally.
I've fixed electrical issues on several vehicles by running dedicated ground cables directly to the alternator and the block. You'd be surprised what some ground connections are (sheet metal bracket on a Nissan Maxma that was known to eat alternators until I ran a dedicated ground to an alternator case stud).
Did that alternator show that it was not charging? Changing a good one for a good one is not going to solve your problem.
