New information. I recieved my free replacement in the mail yesterday (aust EST) and immediately went out to replace same. Getiing out my trusty multimetre to make sure all the polarities were correct i came upone something very rare and it still has me stymied . The reversing loop and a switch decoder are connected to a 1052T isolating unit. to provide connection to the main rails to pick up connection from MTS and i found a 186 ohm resistance within its terminal block, on the blue or outer leg. I checked it about a dozen times and got much the same every time say 194 ohn maximum. I shorrted the problem out and connected everything up and it works perfectly! I don't know for sure; as i couldn't get under the printed circuit board type connection to inspect it properly but i suspect ants, as they are pretty prevalent in this area. Questions. 1/ Does any one else think it it could have been ants and if so how could they cause this problem? 2/ Does anyone think it may have caused the capacitor to blow in the reversing loop module? I had the idea of a constant wattage device as the voltage across it dropped the current would increase, any chance? 3/ How could anything run in the reversing loop with this terrific resistance in it? 4/ does anyone thing the wet weather may have excaserbated the problem? 5/ This is a very odd resistance to happen by chance, too high for a partial short and too low for a high resistance joint? 6/ How did the switch decoder work under these circumstances and it must have as it was on the same circuit. Lets hear what you think gentlemen. Rgds ian
