Hi, my name is ***** ***** I will try to help you. Do you have a multimeter to check the charging (or not charging) voltage when the car is running?

Customer: replied 5 months ago.
No sir i dont
Customer: replied 5 months ago.
If i did how would it help
Expert:  Joshua Haynes replied 5 months ago.

We would be able to test the efficacy of the charging system. without it, there are a few things you can do to test it, albeit somewhat dangerous for the pcm to do so.

Customer: replied 5 months ago.
I believe i already tried 1 of those dangerous things what is pcm
Expert:  Joshua Haynes replied 5 months ago.

The pcm is the main computer on the car. what have you tried that you are referring to?

Customer: replied 5 months ago.
Start car and take off neg cable to see if will continue to run thats before i changed alternator

Customer: replied 5 months ago.
