Found a burned up chime coil in Spanish Eyes. Upon investigating I disconnected the coil and measured the voltage to the coil (unterminated wires) and there was correctly 26V when the 100 point or 1000 point switches closed, but with the switches open I measured about 12 volts. I have checked the continuity from the chime coil lead (B-G) to the yellow (power) wire and when the relay switches are open there is no continuity. Why am I reading 12 volts on this open circuit? Is this some kind of induced voltage due to the wiring, or what?
