one look at this explains a lot. I see a lot of stress and anger, common among us.

I suggest you try and stay focused on the elevator issue. "Leave the politics to the politicians".

I'm wondering if you have the manuals and prints for this unit? If you do not, www.vertexindustries.org is the non-TKE supplier. The building owner will likely have to purchase any and all info the your unit.

Looking at your posts I don't see you mention if you checked the I/O for that floor?

Job has prints. I have manual. No I have not checked that floors IO. I have yet to plug in tool. Something hooked to P24C in the car station is blowing F2 & F3. I think I lose communication to clc when I unhook P24 in pumping unit.

Unplug P24C on car end, and controller end, meter out, maybe you have a damaged traveller. If okay there, than proceed to remove all P24C driven conections in car and meter until you find the short.

To update my first post.I fixed the issue with this car blowing F2 or F3 or both. I isolated it to the car station terminal strip P24 terminal. It would hold the fuses with the wires disconnect on P24. I traced P24 to the toggle switch at bottom of cop back to terminal strip as P24C. There were 6 wires on P24C. I unhooked all them and one at a time hooked them up until I blew the fuse. The last wire to check was it. I then had to trace that wire to the cartop and it was a wire going to the SELECTOR! Who would have thought that? After removing the selector board I followed the trace from the plug to a diode. Of course the diode tested ok soldered to the board, but to check it properely I unsoldered one side and it was shorted. New selector board, reentered all parameters and did hoistway learn and I was happy to have fixed it.

Thats good troubleshooting right there. Thats why we get paid what we get paid. We are the best of the best. Good job.

This example is what separates the good from the bad mechanics. Being able to find a short from common ccts, separate those and then find the short point can be very difficult but very satisfying.

Hunting down shorts and grounds is the best. A real challenge that separates the men from the boys so to say. And for extra excitement nothing like the old relay Westinghouse with soldered connections to add to the fun.

Having a mod crew tearing out b-base is fun fun fun. Some things are grounded in the oddest locations. And sometimes your company has a ton of mod work so the last few guys get hired off the bench and you get some real winners. Instead of starting at the controller or selector to start cutting this stuff out this genius starts at the motor and works his way back. I've had to put on my big boy pants and rack my brain way too many times(same guy every time). One of the few times I've asked for a adjuster asap. Guys my age don't have the troubleshooting skills the old timers have. If there isn't a port to plug in the service tool they are lost. But guys like me Im just lost all the time
