what are the three triggering devices for ignition systems currently in use today? {Ans: Optic sensor, AC pickup coil, and hall effect switch}Why shouldn't analog multi meters be used {Ans: -Because they can damage computers on vehicles. They use a 9v battery and can send voltage back into the computers that run on 5v references.}Alternators with a charge indicator lamp should be checked for what if a no charge issue is occuring {Ans: -Make sure the charging indicator lamp is illuminating when the key is turned on. If not ground the L terminal and if the lamp still doesn't illuminate then check the circuit for shorts or a burned out bulb. -If this lamp doesn't illuminate then the alternators regulator wont receive the signal from this lamp and wont allow the alternator to charge.}Rectification {Ans: -The process of turning AC voltage into DC voltage with the use of a diode}primary phase increases charging voltage to about what voltage {Ans: around 400 volts.}AM {Ans: Amplitude}
