Dear colleagues. Thank you sincerely for advice to date. Jon, the contactor was energised to enable the current test, good thing I left my tong tester there. Current in other 2 legs seemed normal and ok. The red phase windings were very hot, much hotter than the other 2 sets. Mark, I checked the diodes and the pin was loose on one of the diodes and turned around easily as you stated, so hopefully it was mechanical failure as you state, also when it cooled the lamp came back on. I was personally amazed at the small diodes used for a large current, they will be replaced with larger ones as soon as practicable. Stan, have sent you a personal note re the book and specs. Thank you again for info. My next screening at this particular theatre will be Thursday, so hopefully I can post some good results acting on info received. John S.
