Alternators and Tips on How to Troubleshoot it ?
When an issue occurs with one’s aircraft the ideal procedure typically begins with replacing the basic parts of the aircraft till they fix the problem. Most of the time this is not the best resolution if the pilot wants to fly immediately. Understanding the minor basics will save you time, money and effort in trouble shooting your own aircraft.
Understanding the Alternator takes minor knowledge to understand what it exactly does. An alternator is a device that continuously rotates electricity through the aircraft and recharges battery. Alternators do not generate power to start the aircraft but have enough to have it run efficiently and can distribute the currents else were. An alternator is an essential part of the running of an aircraft but can be quite fragile. “Alternators are able to produce full rated output at low engine RPM.”
The Generator is the what produces electrical power and is regulated by a voltage regulator. The difference between an alternator and the generator is that the generator creates the power when the battery is completely discharged and alternator cannot due to lack of permanent magnets.
Load Shedding is one of the biggest contributors to the lack of energy in an aircraft. The main concern to loath shedding is to turn off all unnecessary outlets to preserve all possible energy that can be leaked. Highly recommended to loath shed to avoid losing communications and navigation. Being able to locate the circuit breakers and be knowledgeable of your service manual before you attempt the to load shed with your aircraft.
The Alternator switch is a small possibility that may go a long way. Corrosion on the switch can be overlooked most times but often accidentally throwing off the system voltage sensing function of the voltage regulator or AC.
The next step would be to attempt a “alternator ripple tester.” Begin with taking the digital meter and set it on AC mode. Next dial the voltage range to about 2 volts and ignite the engine. This will create you to have a 0.1-volt AC which is the lower the better.
IF all these tips fail result in reading the instructions manual as manufactures often include installation instructions. Understanding the basics on mechanics of your aircraft will go a long way when figuring out the problems with your aircraft.
