P3x 54 #1 Posted February 19, 2011 Hi All, The tachometer on my 520H is erratic/inop. Sometimes it pegs and stays towards max RPM on the guage, other times it stays at half guage while other times sits at 0. Does anyone have a checkout procedure using a Volt-Ohm meter to determine the fault? Thank you P3x Share this post Link to post Share on other sites
