Those clutches should pull 3-5 amps. Over 5 amps is too much.
your clutch should have 2.5-3.5 ohms resistance. And of course, not be shorted to the cover or crankshaft. fewer ohms means winding has an internal short and current will be higher causing other components to overheat.
Those models are notorious for killing the backup safety switches because they are in constant use. Also, sometimes the clutch lining wears to the point it does not engage every time, especially when hot.
Just fixed one a guy was running commercially a month ago.
