Possibly it could be =3D somewhere on the relay as well.. However if you have spark suppression =3D diodes mounted separately from the magnets the common return wire on the = =3D diodes can easily get put on the wrong side of the power supply. Noisy =3D chaos will occur! Also a faulty diode can cause similar problems at =3D times.   I had a major problem like that 25 years ago with a big old Casavant =3D which had been moved some years before to a new church.. The organ =3D would go into a severe case of epilepsy when more than 4 notes were =3D held. Pipes sounded, shutters banged and the stops would violently turn = =3D on and off with a terrific ferocity. The cause was a loose feed wire =3D to the pedal chest that vibrated on and off whenever several pipes were = =3D played. - And a bad case of lousy wiring by the installer.   The hard part was finding the loose connection which was buried deep in = =3D the bowels of the organ. I only saw it after 4 hours of searching. The =3D sparks flashed in the dark when the lights were turned off, just as I = =3D was about to go home feeling total frustration. and failure.       --- Outgoing mail is certified Virus Free.
