Some great ideas...I especially like the one with the flexible leather strap with holes in it. My Estey, too, had quick disconnects at the magnets. They consisted of little soldered rings at the end of the cable wires that slipped over hair-pin-like wires at the magnets...NEAT! About the CODE....does this mean I should replace all the wiring in my Aeolian player console? What chance of fire is there from 12-24 Volts? I = am not being sarcastic, I really don't know! Thanks again, Berley

If you have a dead short in most any = DC circuit, ignition temperatures can be generated. Don't believe it?--Bend a paper clip to short the terminals of a 1 1/2 volt AA battery and you won't = be holding it for very long. 12 to 24 volts in dead short situation will heat = a 1/4" chunk of steel cherry red. From what I have seen of pipe organ electrical systems with their = fully exposed terminal blocks and non insulated common buss bars, the potential = for a dead short caused by any metallic debris falling between the 2 sides of = the circuit is very high. I would want fuse or circuit breaker protection for = the lowest possible amperage I could get away with. And that cotton covered = wire is just kindling for any potential dead short situation.
