Customer Question

2000 Dodge Neon. (Note: I am a very experienced mechanic, and this problem has been leaving techs stumped for years... many people have same problem). The Battery light comes on after about 1/2 hour driving. Turn off engine, restart and battery light is now off. 1/2 hour later... back on. Same... Battery good. Alternator good. Battery cables good. Clamps at battery removed and cleaned and connections now confirmed good. All wires to alternator cleaned and checked; (no problems found). Again, many people report same problem dating back at least 10 years. All "normal" solutions never resolve problem (including PCM replacement). Note: Some models have a battery temperature sensor, but mine does not. Code reader shows zero codes. I would be glad to pay for a solid answer, but the "usual" answers will not be helpful. I do not mean to be rude, but please don't ask for payment unless you _know_ the answer to this problem.
JA: Have you tested the battery? Have you tried testing the alternator?
Customer: PLEASE read my message.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: PLEASE read my message.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Dodge Mechanic about your situation and then connect you two.

Hi there.

Not meaning to be rude myself, but it sounds like you're just not using the right tools. Do you have a scanner capable of reading charging system PID? If so, monitor those and let me know their values. Based on those I'll give you the solid answer you want.
