Electrical issues

Hi and thanks for using 2CarPros.

It sounds like the alternator has failed. What I need you to do is perform a simple test. Follow this link:

You will need to recharge the battery prior so the car will start. However, if you have a simple volt meter, you can do this. Here are directions for using a volt meter:

If you don't feel comfortable testing it and can drive to a parts store safely, most of them will do it for free. Or, you could disconnect the battery, remove the alternator, and then take it to a parts store to have it bench tested.

If you decide to remove the starter, here are the directions for removal and replacement. Note: Make sure to disconnect the battery prior to the removal process. While it is disconnected, recharge it.

Removal and Installation

REMOVAL
1. Disconnect the negative battery terminal.
2. Remove engine cover.
3. Remove front wheel and tire (RH).
4. Remove splash guard (RH) See: Front Fender Liner > Removal and Replacement > Exploded View.
5. Remove air cleaner and air duct assembly. See: Air Cleaner Housing > Removal and Replacement > Removal And Installation.
6. Remove drive belt. See: Drive Belt > Removal and Replacement > Removal And Installation.
7. Remove A/C compressor. .
8. Remove idler pulley.
9. Disconnect the oil pressure switch.
10. Disconnect the alternator harness connectors.
11. Remove the alternator bolt and nuts, using power tools.
12. Slide the alternator out and remove.

INSTALLATION
Installation is in the reverse order of removal.

CAUTION:
- Temporarily tighten all of alternator bolt and nuts. And then tighten them in numerical order shown in the figure.
- Be sure to tighten "B" terminal nut carefully.
- Install alternator and check tension of belt. See: Drive Belt Tensioner > Removal and Replacement > Exploded View.
- For this model, the power generation voltage variable control system that controls the power generation voltage of the alternator has been adopted. Therefore, the power generation voltage variable control system operation inspection should be performed after replacing the alternator, and then make sure that the system operates normally. See: Charging System > Initial Inspection and Diagnostic Overview > Inspection Procedure.

Are both lights staying on when the engine is running?

Hi and welcome back:
The only common denominator that I see is the ECM, ABS, traction control, and Alternator all ground on the engine.

On the rear of the alternator there is a wiring harness that plugs into the alternator. There is a black wire that is in that harness. First, I want you to disconnect the battery and then unplug the alternator. Then locate the black wire in the plug and check if there is continuity to ground. Move the wire around to see if it changes things. If continuity is good, I want you to run a separate ground wire between the engine block and a known good ground on the frame, body panel, or even the negative on the battery. Connect it to a clean location on the engine to provide an additional ground.

Reconnect the battery and see if that changes anything. The reason I am suggesting this is because although these different components ground at the engine, they are at different places on the engine. Therefore, if the engine itself doesn't have a good ground, the components won't either.

Do this and let me know what you find or if you have other questions.

Take care,
Joe
