Obviously the IFR is getting power from somewhere....you have to find out where. Your profile states trainee.....where's your trainer? Whoever's teaching you needs to help you more just looking at your questions, such as how to clean a coil. If you're paying someone for this training, get your money back.
If everything was always done "by the book"....the book would never change.
