My question is: The new Craftsman DMM I purchased is giving me odd diode
reading using the pinout diagrams for my particular diodes and
transistors. Do I have to desolder these diodes and transistors I've
isolated as a likely cause for blowing a fuse on my power board and test
them, or should I be able to test while they are in circuit and on coils
underneath the playfield? Thank you.

I find a lot of these components will fool you when you test in circuit. I usually just clip out the diode, test it to see if I found the problem and then replace either way.

If I don't have a spare, I unsolder 1 side and test it.

That is my $.02
