China tach doesnt work
Ha, no **** right? New "Autotecnica" digital tachometer with digital and lcd sweep readout. Kinda cool for $16 shipped, only to use it to set idle speed on a non tach equipped 2.0 82 Mazda from under the hood. 3 wires : hot, ground, and signal to - slide of coil. So far as good. I hooked it up while idling and the sweep registered so RPMs then returned to zero. Took sense off and touched it again and same thing. A blip then zero. F this, took it apart and it's all surface mount except 1 capacitor. I'll pull and test, maybe it went south. << The 'Autotecnica' that's in the display never illuminates , I only saw it light when I touched the display leads with my fingers and everything lit up. This tach is on the Autotecnica Australia website at $80 so maybe this is a failed QC reject that Amazon sells for $16?
