[600MRG] Maiden Voyage - Somethings Not Right

Just thinking........

Would a commercial clip-on AC ammeter like that is used in the electrical

... make a series circuit with a 100 watt light bulb and VOM or DMM (that
measures ac current). If you don't have a VOM or DMM just calculate the
current ... for a somewhat more rough idea.
