Can 2N3055 be replaced with 2N3773 as it was mentioned in other forum? datasheet: http://www.ortodoxism.ro/datasheets2/b/0f582lg1l7hqtexofow7tsggc5cy.pdf
Hi! Here is my ignition coil There si little more tham 1cm space between wires. I need to fix that driver, because I didnt have samo parts like on scheme. Sorry for bad quality :P I have captured this images from video recorded on my mobile phone.
that colored ring is pointing to ground (0V) ??? Here are some more measurments on -5.6V elements: Ud5=266mV Ur2=0V Ud6=420mV Ur3=5mV Ur14=-220mV (common of instrument was on Q1 base) Uc2=40V (common of instrument was on negative of cap.) Uc3=650mV (common of instrument was on negative of cap.)
I have desoldered -5.6V elements and measured them, but they are working properly. Im not sure for D7 zener, because I don't know how to measure reverse voltage (5.6V).
