I 100% agree with everything you said and I agree with the knowing the multimeter. I’ve done a lot of troubleshooting in my life but there is not from what I’ve seen in this forum (I’m sure I need to dig deeper) a presentation of what is inside these machines and what each component does. The only way I have learned in the past month is from what the knowledgeable people on this forum have told me. Example the Netplex board and the fact that I can plug it into the other two pin receptacles on the board. I truly appreciate the knowledge that this website has passed and look forward to continuing with this hobbies and the troubleshooting/understanding of this machine.
