Flying the turboprop today and I noticed during preflight that as soon as you turn on the prop heat it shows a large load on the alternator on syst amps - even when you don't have the prop heat test button depressed. No load on the prop amps until you press the button. Is there something else that's being energized? Checked the manual and couldn't find anything.
