Can a bad PCM cause battery drain?
Can a bad PCM cause battery drain?
Lastly, a failed PCM relay can cause the battery to drain over time due to the switch constantly being turned on, or a dead battery. If they relay short circuits, it can drain the computer battery, even when the vehicle is turned off.
What are the symptoms of a bad alternator in a Chrysler Sebring?
It’s the labor that makes the job expensive. Here are the most common symptoms of a bad alternator in a Chrysler Sebring: The battery light is designed to tell you that there is not enough voltage to properly charge the battery, or that the battery itself is not holding the proper voltage.
What should the volts be on a Sebring?
With your Sebring turned off, you’ll connect the negative side of the meter to the negative battery post or wire. You’ll then touch the positive side of the voltmeter to the positive battery wire. With the engine off, you should get a reading somewhere between 12.0 volts and 12.6 volts.
Can a bad serpentine belt cause an alternator to fail?
It’s worth noting that a bad serpentine belt can cause the alternator to stop charging effectively. It’s pretty easy to tell if one is bad. It’ll look dry rotted. If it’s been slipping a lot it’ll have a glossy shine to it. You’ll have probably heard it squeal when you start the engine. They typically don’t fail quietly.
Do you need an alternator for a 12 volt car?
If you got 14.2 or more volts, the alternator is charging fine. If it’s still showing in the 12’s, it’s time to replace the alternator. If it’s producing a voltage level in the 13’s, go ahead and take it into a parts store and have it tested. It’s probably bad.

Can a battery voltage test be done on an alternator?
One test is not enough if you are diagnosing a charging system problem. All too often, the alternator is condemned as the source of the problem if only battery voltage is present with the engine running. If this is the case, it only means that the alternator is not charging, but does not reveal why.
When does the alternator light turn on the battery?
On older vehicles, the battery light would turn on the alternator light when the alternator output or battery voltage dropped below a preset value. The battery light on modern vehicles, however, is controlled by data and trouble codes. This is why a scan tool is essential to diagnosing a charging system.
