just one little step.....
last night after make some wiring work I've got a right ignition signal on
pin 22 from my ECU
when I ground pin 2, and connect test led between pins 2 and 22.. turn on
ignition, and try to start the engine and the test led BLINKS :)))
so at this point I have one problem - how to trigger the coil. HF8311A seems
to be failed, so I must find a replacement. bad thing - I dosen't have an
idea what's the spec of this HF8311A.
Have some one changed this trigger transistor before?
