Thank you for asking your question on JustAnswer.
What signs are you seeing?
Have you tested the alternators on the car?
You are going to need to have the alternator tested on the car, if you are sure the alternators are good then you will need to see if you have the proper power supply to them when the engine is running.
There 2 fuses you need to check if they are good , have the alternator test on the car.

You can take it down to most any major part store and the can run a charging system test. I would also have a look at the 2 fuses that control alternator.
I have marked the fuses you need to check
Sounds like a good plan

that was it! thanks
