Aircraft Voltage Regulator Troubleshooting

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.

Aircraft voltage regulator troubleshooting.

Good grounding eliminates many potential problems. Check and record voltage of aircraft bus. If the g the kelly aerospace vr2000 offers built in troubleshooting diagnostics to identify elec trical system problems all the while. The voltage on the armature post should follow the throttle.

Check the two wires from the generator to the voltage regulator. Use the troubleshooting guide for repairs on our aircraft alternators. The input voltage should be approximately the same as the bus voltage. 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. 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. 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.

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. Need help solving an electrical system issue. Verify both the input and output voltage of the regulator.

The following applies to plane power r1224 voltage regulators. Voltage regulator troubleshooting tips. As such regulator maintenance other than basic adjustments are minimal. If it does the generator is o k.

If another manufacturer s voltage regulator is installed refer to their maintenance manual.
