I think it's fixed! RE: caps. Plus a question

It looks like the problem wasn't caps after all. Or the time delay relay. While poking around inside the electrics enclosure and putting number labels on wires so that I could remove the contactor I found a female spade connector just hanging behind the contactor coil spade terminal. It's really hard to see the coil connections because it is buried pretty deep and a lot of wires are in the way. So I pushed the spade connector back on and it just slipped on real easy. Too easy. I pulled it back off and wormed the wire through the others and could see that the female connector was open too much. Maybe years of vibration loosened it. So I closed the connector some with pliers and when I tried pushing it on again it was quite tight. After putting the rest of the wiring back in order I tried starting the RPC (Rotary Phase Converter) and it started normally, which is essentially instantly. Now I have another question. Since the spade connector was loose could this have caused a high resistance connection which in turn caused the contactor to barely pull in which then made for another high resistance connection between the starting caps and the motor? I know that at least some types of relays have a higher pull in current than the holding current. So that once they pull in less current is required to keep the contacts closed. In other words a curve of the current required is shaped like a hill, with the holding current past the crest a little. But I think that maybe contactors for motors may work differently because they have so much more travel in the solenoid after the spring loaded contacts first make contact, unlike "regular" low current relays. And since the current required to pull in the contactor remains the same even a slight decrease in current would cause the contactor to drop out. And maybe a low current situation could cause the contacts to make only a light, high resistance, contact. Anyway, thanks for reading all these posts and thanks for the advice given. While writing this post I have started the RPC 6 times and each time it has started normally. Cheers, Eric
