Aircraft Voltage Regulator Troubleshooting

If it does the generator is o k. As such regulator maintenance other than basic adjustments are minimal. This is because the voltage output of the alternator must greater than the battery voltage or current will not flow into the battery which on its own should produce about 12 8 volts when fully charged.

Voltage regulator troubleshooting tips.

Aircraft voltage regulator troubleshooting.

Troubleshooting guide for all single engine externally regulated alternators. Check the two wires from the generator to the voltage regulator. The voltage on the armature post should follow the throttle. Check and record voltage of aircraft bus.

The input voltage should be approximately the same as the bus voltage. Aircraft alternators are externally regulated by a voltage regulator sometimes called an alternator controller which is usually mounted either on the firewall in the engine compartment or under the instrument panel. Generation regulator incorporating gfp the voltage regulator will not be damaged and the gfp circuitry will take the electrical sys tem off line instantaneously precluding air craft wiring or avionics damage. These solid state regulators along with glass cockpit warning systems are providing faster but not necessarily better information to the aircraft s pilot and mechanic.

The following applies to plane power r1224 voltage regulators. Verify both the input and output voltage of the regulator. Normal readings should be around 14 volts for a so called 12 volt system. Need help solving an electrical system issue.

Most aircraft voltage regulators used today are solid state and no longer have the trouble prone contact points and coils. Make sure that when the master switch is on that you have battery voltage of at least 12 or 24 volts on the regulator battery terminal. If another manufacturer s voltage regulator is installed refer to their maintenance manual. This video provides the basic steps for troubleshooting aircraft electrical system issues including headset noise.

Which in turn decreases alternator output voltage. Use the troubleshooting guide for repairs on our aircraft alternators. If the g the kelly aerospace vr2000 offers built in troubleshooting diagnostics to identify elec trical system problems all the while. Good grounding eliminates many potential problems.

Record aircraft bus voltage.
