It may have a thermal fuse wound into the outer layers of insulation - if you unpeel it carefully (those wires are likely to be very fine and easily broken) you may be able to short it temporarily and measure the secondary voltage. Don't be tempted to solder in a new thermal cutout - the clue is in the name! :-) Cheers, Howard Winter St.Albans, Herts -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
