Hello, I need direction. My battery won't take charge. My car is an 06, 2.4L. I replaced the battery, starter and alternator because my car wouldn't start. Ultimately I found that the clutch switch was the cause for the car not starting. Now the battery light is on, on the dash. I put a meter on my battery, initially I would have 12.5 volts, I let the car run over a period of time and the volts would drop to 9. I believe if I were to let it run the battery would and the car would stop. Can anyone tell me what I could look at next too possibly solve this issue? Thank you in advance. Oh one more piece of information. When I attach my scan to the port under the steering column, it has no reading at all, it's blank? Also I cleaned the ground connection on the engine.
