CHECK THE PIGTAILS!
Jim,
An T337H owner I met a year or so ago changed his entire engine instrumentation over to Electronics International units that are manufactured in Eastern Oregon. The finished product looked pretty slick, with the TACHS and MP gages showing both digitial and color dots. HOWEVER, the original TACHOMETER indication system on the 337 is pretty fool proof, with most of the headaches arising where the pigtails from the extra set of points on the magnetos connect with the ships wiring. BEFORE you go out and spend a small fortune testing the OEM gage or investing in new gages from EI, I think it would be HIGHLY PRUDENT to check the wiring at each end of the run where the pigtails are located... all you may have to do is change out the connectors, which are about .50 cents apiece. There's not much to it... JUST TIME!
