If the battery is fine, then the fuses for the charging system need to be checked. If one of the wires for the alternator shorted when the alternator was replaced, then this will occur. If this occurred right after the alternator was replaced, then there is something that shorted when the alternator was replaced.

Most of the time, there’s a high-amperage fuse or fusible link between the alternator’s battery terminal and the battery. Also, there are usually low-amperage fuses in series with the alternator’s sense terminal and ignition terminal. Like any fuse, the primary alternator fuse acts as a circuit protection device.
Can you spray WD40 on alternator?
No, you cannot spray an alternator with WD40. As I said earlier, WD40 is a fluid cleaning agent.

What does it mean when you turn your key and nothing happens?
If nothing happens when you turn the ignition key to the “Start” position, it means that the starter motor doesn’t turn over the engine. The starter motor itself or a starter solenoid could be bad – it’s a common problem at higher mileage. Read more about the starter motor.
Can a car battery be so dead it wont jump start?
Absolutely. A dead battery with a dead short will not be able to be jumped, A dead battery with an open may or may not be able to be jump started. A fully depleted battery may need to be charged for a few minutes from the donor car before it is able to start.
How do you tell if its your battery or your alternator?
If your engine won’t turn over or takes far longer than usual, it’s time to grab the jumper cables and attempt a jump-start. If your engine starts and stays running but won’t start again later, it’s likely a battery problem. If your vehicle immediately stalls, it’s probably a bad alternator.
How do I know if it’s the battery or the alternator?
An illuminated dashboard light can indicate a problem with an automobile charging system. However, a very simple way to check if the alternator is working is to run the car and disconnect the positive terminal of the battery. If the vehicle stops running, then you probably have a bad alternator.
How do you diagnose crank no start?
Ignition timing on a no-start can be confusing, but it can still be tested by connecting a timing light, then watching the timing marks while an assistant cranks the engine. While this may or may not be base timing as specified by the manufacturer, it does let you know where the spark is occurring.
