Thank s for the responses
Solid State
The old timer had definitely pass on some of his wisdom!
I've no experiences with the yellow jacket relays. Every unit I've seen with these relay base type has had the IBM relays. I will say it is nice when you trace the trouble out that you can see the faulty contact.
Philly What is the function of the LED? To tell you the coil is energized?
Also, thanks Jim Collett the sequence info for call canceling was spot on!

I used to think that an oletimer was just lazy by telling me to check every IBM relay. He would say pull them out,blow them out and look at them. He would not even trace the schematics. He also liked to say the female plug contacts could be loose, so squeeze them tight before you plug each one of the relays back in. Any time there was an issue that was not obviously a mechanical problem this was his solution. The crazy thing was once he was called in,the same problem never happened again. And it was never a parts charge. Just labor. Now we have the yellow jacket relays, in every unit that has not been modded. Yes...I can attest that the above method does work. Back then it was part of routine anual maintenance. In this day and age for a building to pay the kind of money to keep one of these things in tip top shape, it is far more cost efficient to modernize. Surely Broke Sheave, you are not saying that you are an ole timer? LOL.
