Any particular kind of car and motor?
The voltage regulator is NOT built in the alternator, it is part of the ECM, that is the Engine Control Module. The module (computer) monitors the charging system and signals the alternator how much voltage to send it to keep the system working properly. the voltage regulator is built in to the alternator
To cool the SMPS while the computer is working.
Cooling fan not working. need wiring diagram or some information on how to repair.
Yes you can take negative off on all cars and test it if it dies alternator is bad if car keeps running then its good. In older (not computer controlled) cars you can, but on some newer (computer control) cars is not recommended. Some newer cars will turn off even if the alternator is working good. Use a volt meter to test the voltage. Connect it to the battery and it should read a little above 12 volts when its off and 13 to 14 volts when its turn on. If the voltage does not go up, then the alternator is not charging.
Cooling fans are controlled by the computer based on input from temperature sensor. After the vehicle is shut down, if the temperature is still high, the computer will turn on the fans to cool the engine.
Go to the control panel and troubleshoot it.
CAUTION!!! This may be a problem with the alternator and the charging. Blower fan will stop working if alternator is not charging. You may also see the battery light and brake light staying on as well! Advance Auto Parts or Auto-zone can test your alternator/battery.
I had the same problem...the alternator went bad. Both the alternator and battery had to be replaced.
Hi the tacho runs off the alternator & when it stops working it is normally a sign of a fault with the alternator so firstly i would check that the alternator is working corectly
To control and optimise the working temperature of the engine during differing load conditions.
your cooling fan(s) is/are not working your cooling fan(s) is/are not working
If the water cooling system and control rods stopped working, the nuclear fuel could overheat and lead to a meltdown. Without the cooling system, the fuel would continue to generate heat and could potentially breach the containment structure, releasing radioactive material into the environment. The control rods are essential for regulating the nuclear reaction, so their malfunction could result in a rapid increase in reactor power output, further exacerbating the situation.
