Aircraft Voltage Regulator Troubleshooting

Good grounding eliminates many potential problems.

Aircraft voltage regulator troubleshooting.

If the g the kelly aerospace vr2000 offers built in troubleshooting diagnostics to identify elec trical system problems all the while. Normal readings should be around 14 volts for a so called 12 volt system. Which in turn decreases alternator output voltage. 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.

The voltage on the armature post should follow the throttle. 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. Most aircraft voltage regulators used today are solid state and no longer have the trouble prone contact points and coils. This video provides the basic steps for troubleshooting aircraft electrical system issues including headset noise.

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. As such regulator maintenance other than basic adjustments are minimal. The following applies to plane power r1224 voltage regulators. The input voltage should be approximately the same as the bus voltage.

If another manufacturer s voltage regulator is installed refer to their maintenance manual. Use the troubleshooting guide for repairs on our aircraft alternators. Need help solving an electrical system issue. Troubleshooting guide for all single engine externally regulated alternators.

If it does the generator is o k. Verify both the input and output voltage of the regulator. 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. Record aircraft bus voltage.

Check the two wires from the generator to the voltage regulator.
