Finally, a proper way of looking for bad MOSFETs. I've started trying to fix ECUs for 2 months now and it bugged me really hard when i saw the experienced folks using continuity mode for checking any sort of MOSFET. Basically anything that didn't read bellow 50 ohms it was judged good and they look for problems elsewhere. Great video, definitely very informative. Also, what is that benchtop multimeter you're using? It's has a pretty dang fast auto range :D

Good video on testing the ignition IGBTs. My repairs have not gone so smoothly. The igbt driver IC seems to be turning on 3 of them at the same time, burning up the current sensing resistors. (cylinders 1,3,6) This chip appears to be discontinued and has no useful data sheet, so I cannot find a substitute. I forget the number, since the scrap of paper I scribbled it on is at work with my wrenches. I will post the number tomorrow. Are these available at all?

Ah, here it is 74022PC, the gate driver IC. The other parts are available.

Do not buy igbts labeled 5503GM or the logic gate labeled 74022. These are masked numbers ford used internally. Anything aftermarket is just fake chips that may or may not work. Use updated igbt from onsemi and a compatible 7402. Buy from real supplier like digikey or mouser.

Use promocode "SAVE10" for extra 10% off cause I love doing those older ones. Specially if it needs some trace repair! Fun stuff. > keyworks.us/ford-lincoln-mercury/engine-control-module-repairs/ford-f-series-87-99-ecu-repair.html

Im not sure but I assume most of it was done by pick and place machines and then wave soldered.
