Use a voltmeter. No need to use A-tap...it's not always accurate with this particular situation. Some people have read 100% opening at WOT but only see 4.5v on a voltmeter. 4.6x volts is full opening. FWIW, mine read about 4.62v with no grinding. Be sure you floor the gas pedal and get someone to check the voltage then too, to make sure your throttle cable isn't loose. Mine still read 4.62v that way as well.
