The Mustang battery
plays an important role in the Mustang ignition system
, as it starts the process of building a charge that eventually goes to the Mustang spark plugs
to ignite the fuel and air mixture that gets injected into the cylinders. However, you might wonder what keeps the battery fully charged for starting your Mustang and beginning the process of building the charge that will eventually proceed to the spark plugs and ignite the fuel/air mixture in your Mustang's cylinders. Two parts handle the charging process: The alternator and the Mustang voltage regulator. The alternator is what provides the actual voltage to the battery. However, it's the Mustang voltage regulator that determines whether that voltage actually gets to the battery or not.
Typically, batteries need to be kept at between 13.5 and 14.5 volts, and it's the Mustang voltage regulator that keeps it there. If the battery is at 14.5 volts, the Mustang voltage regulator causes a break in current to stop the battery from charging or shuts the alternator down completely and prevents the battery from overcharging or even exploding. However, if the battery falls below 13.5 volts, the Mustang voltage regulator begins to allow current through again, to fully charge up the battery.
In most models, the Mustang voltage regulator is found inside the alternator. That type of Mustang voltage regulator is simply replaced along with the alternator, as these Mustang voltage regulators and alternators are one unit. However, in most classic Mustangs, the Mustang voltage regulator is a separate part, so that type of Mustang voltage regulator can be separately replaced if the alternator is still working well.
CJ Pony Parts stocks many Mustang voltage regulators for classic Mustangs. The Mustang Voltage Regulators
available are both aftermarket and stock style, so you can find the perfect one for your Mustang.
