I just had my battery, alternator, and alternator belt replaced. It started a few days ago when I go out in the morning the car is completely dead, no sound dings, lights, clicking etc. I did have all the above mentioned replaced. I noticed they forgot to put my AC compressor belt back on (not sure if that could cause the issues still). After having all that done I’m still having the same problem. When I put a jumper pack on it starts with in seconds. Hope some has answers. Thank you in advance!
