Can someone help me in finding replacement components for a 16-year old automotive (Mazda) diagnostic module ?
Diodes:
Using my Fluke 79 DMM set to the "diode" mode, all of the circled diodes are testing "open" in both directions, which supposedly means ALL of these diodes are "open" and need to be replaced.
The only markings I see are a "D" or "O" and a "4" (see attached pics for details).
Transistors:
NEC J143
NEC B1151
K105
Thanks,
neil
BTW: input voltages are only 14.2-VDC, electrolytic caps are rated at 25-VDC, and have been replaced.
