Hello all I am robert i am in my 7th year of the trade, started in New construction and mods and branched out to service when they were needing help learned (and am still learning ) tips and tricks through troubleshooting and understanding more complex issues on older relay logic and composite. My ask is anyone willing to share and manual or prints for units all brands, size, model to expand my technical library. Im generally increased by how things have changed over the years and enjoy learning more and more I'd be willing to search what I got for anything needed as well thank you ahead of time.
