Welcome, I'm Chris (aka Moose) I'm an independent contractor here at Just Answer.
The previous tech opted out, would you like my help?
Thanks for asking your question and letting me try to help you.
When you did you charging system test and got 14.1 volts was that reading taken on the battery posts idling in park with headlights, wipers, and HVAC on?
Disconnect the negative battery cable. With all doors closed, no lights being commanded on, like a hood light if applicable. Connect your volt meter to the negative post and negative cable. What does the meter show in the DC milliamp setting?
I like to stay in contact with my customers that appear not pleased, still working on the concern, or have not rated yet. I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.
