pizzaguy ... I commend you for this adventure ... I have had other types of training in my past that were "use it or Loose it" type ... meaning it was something you could forget if you didn't regularly use what we were taught ... Do you find the electrical side of things fall into that area? I have often thought it would be good to know and understand what I was checking and why ... but checking and/or working on electrical is not something I do on a regular basis ... Thank for offering this to us, and thank you for sharing your vast knowledge of electrical an Crossfire's
