Leo, your enthusiasm for the industry is awesome, but please leave the mechanical work to actual licensed technicians.
I watched a video on your YouTube channel of you flipping the power to (assumingly) the same elevators you are asking for help on, and it appears that the building they are located within is not occupied, therefore there is a pretty obvious reason why the elevators were powered down. Share your passion by appreciating the work done throughout the industry, not by putting yourself and others at risk by attempting to handle equipment you are obviously not licensed to work on.
