Looking for some help here.
I was driving my car and my dash lights, first the seat belt light, then all right side lights, then finally the battery light turned on. A little while later I lost power to my radio and then all gauges. Finally the lost power and then would start without a jump.
I replaced the battery, and alternator, and had recently replaced the spark plugs as well.
The car ran fine for about two weeks, then did the same thing again.
Replaced the ground wire after cleaning the terminals to the battery, still didnt fix the problem.
I am not sure where or what to check next.
Could anyone provide a few suggestions or point me in the right direction.

Use a multimeter/voltmeter, while at the battery terminals:
- voltage while the engine is off
- voltage while the engine is on -> needs to be at least 13.8V and holding in this cold weather, if this is not the case, you still have a bad alternator

The lowest I've seen while the car is running is 12.6v during the fall/spring months and that's with no accessories on at all.
