After installing the alternator, the car starts, but it does not shut off after turning off the ignition. It sounds like the alternator may have an issue with its wiring or internal components, which could prevent the car from shutting off when you turn off the ignition. Here are some possible causes and solutions:
Explanation: If there’s an issue with the alternator’s wiring, it may be ''back feeding'' power to the ignition system even after you turn off the key. This can happen if a diode in the alternator fails or if there's a mistake in how the alternator is wired.
Solution: Double-check the alternator wiring and connections. Look at the wiring diagram for your car to ensure each wire is connected to the correct terminal. You may need a mechanic to inspect and possibly rewire or replace the alternator if it’s a diode issue.
Explanation: Sometimes, the problem can be with the ignition switch itself rather than the alternator. A malfunctioning ignition switch can cause the alternator to keep supplying power even when the car is supposed to be off.
Solution: If the wiring seems correct, the next step is to have the ignition switch inspected to see if it’s failing to cut off power. This may require a replacement of the ignition switch.
Explanation: If a diode or internal regulator in the alternator is faulty, it can keep providing power to the engine even after you turn off the car.
Solution: In this case, replacing or repairing the alternator may be necessary. A professional mechanic can run a test to confirm if there’s an internal fault.
Cause: A damaged or malfunctioning voltage regulator within the alternator can prevent it from properly managing power flow. This can cause the engine to remain powered even after the ignition is switched off.
Solution: The voltage regulator may need to be replaced, either as part of the alternator or separately, depending on the vehicle's design.
Cause: A stuck relay or fuse related to the ignition system can also cause the car to stay on even after you turn off the ignition. If the relay doesn’t disengage properly, it might keep supplying power.
Solution: Check the relays and fuses related to the ignition system. If any of them are stuck or damaged, they may need to be replaced.
Cause: An electrical short or a malfunctioning sensor could send a signal that keeps the engine running. This might be an issue with the wiring or the engine control unit (ECU).
Solution: An automotive electrician or mechanic can diagnose and fix electrical shorts or sensor issues.
Multimeter Test: Use a multimeter to check the voltage coming from the alternator and the battery. If there’s irregular voltage or backfeeding, it could point to an alternator or wiring issue.
Professional Help: If you're not familiar with car electrical systems, it’s best to consult a mechanic to avoid causing further damage to the electrical system.
The primary causes of this issue are often related to problems with the alternator, ignition switch, or electrical system. In most cases, a professional mechanic is recommended to diagnose and repair the problem safely.
