In some cases, a damaged voltage regulator (inside the alternator) will produce too much voltage, which can damage your vehicle. Having an alternator replaced in most cars costs between $200 and ...

If all of those are clear, then check the alternator by testing the battery voltage using a multimeter. With the engine running, it should read out to between 13.5 to 15 volts. Make sure it stays ...

Upgrading Pre-'70 Mopars To The Solid-State, Electronic-Voltage Regulator And Alternator. HOT ROD Staff Writer Dec 01, 2001. See All 7 Photos. Do you own a '69-or-earlier Mopar musclecar?

The switching regulator uses the constant off-time topology –off-time is 300nS –this makes the max frequency approach 3mHZ –frequency is variable, depending input voltage. Free wheeling diode The free ...

The regulator controls the output of the alternator by varying the current through the rotor, more current equals a stronger magnetic field and more alternator output. See All 39 Photos 18.

The voltage regulator is a simple switching device that keeps the alternator from overcharging the battery and, at the same time, helps keep the battery charged to 13-14 volts.

Within the device’s simple-looking five-lead package are an alternator-voltage regulator for 12-V systems with enhanced features to ensure the stability of the vehicle’s electrical systems ...
