In the meantime, I'll check the visible ends. You say the wires are in a raceway on the inside of the mast? Can you follow the time honored Navy practice of abandoning the old wires in place, and running fresh ones outside the bundle. If you get zillion wire cables, they can swing around inside the mast without breaking eventually. Tape them to the outside of the mast, until it has to come down for some reason, and run the wires at that time. Casady The wiring is in a conduit on the outside of the mast, so it is relatively accessible, but independent wiring isn't a bad idea for a temporary solution. I'm not planning on taking the mast down any time soon, so I guess whatever I do will have to be done from the bosun's chair. J |

John, I am not sure this is relevant, but often more than one data inut can be transmitted on a single wire like speed and azimuth, where speed is derived as an ac signal (pulse rate) It could be riding on top of a dc reference voltage used in azimuth calculation. These two pieces of intelligence could easily be separated using capacitive coupling at the receiver. Steve This starts to sound a bit more complicated to this electronically challanged sailor! But I think I get your point - this would mean that a steady DC voltage would prove that the wire is connected (to something) but an absence of AC pulse might imply that the anemometer has failed?
