## Discrepancy

AMMETER FOR PROPELLER DEICE SYSTEM, PIPER PN 548-084, APPEARS MIS-MARKED.  OLD UNIT GREEN ARC IS FROM 20-24 AMPS.  NEW UNIT MARKED 17-24 AMPS.  NORMAL DRAW ON SYSTEM IS 17-18 AMPS.  OLD METER SHOWS 17 AMPS, BUT THAT IS BELOW GREEN ARC, WHICH CAUSES PILOTS TO SQUAWK SYSTEM, EVEN THOUGH IT WORKS PROPERLY.
