AI Thread Summary

The Chrysler 200 2011 is experiencing voltage issues, with reports of the alternator running at 18 volts after replacement, leading to a dead stereo system. The voltage regulator, which is supposed to prevent overvoltage, may be malfunctioning. Some users note that the voltage regulator can be internal to the alternator, while others mention it being part of the powertrain control module (PCM). This discrepancy in voltage regulation could be causing the battery and alternator failures. Proper diagnosis of the voltage regulator's location and functionality is crucial for resolving these electrical problems.

TL;DR Summary: Car running at 18v after replacing the alternator. What should be checked next without having to pay $200 for a diagnostic?

My car burnt out my battery and alternator so I replaced the alternator and now the stereo system is dead when the car is turned on and the alternator is running at 18volts

The voltage regulator should prevent that. Check it out.

Some voltage regulators are internal to the alternator.

The voltage regulator is in the PCM

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
