The LED will not work with lower voltage than 1.5V, so any small voltage made by the magnet going through the coil would not activate the test light. I can't see anything else wrong with it? Any suggestions? ![]() I think the bulle clocks need the magnet strength at about 120mm with the compass test, and 1200ohms resistance for the coil. I'm guessing that either the coil or magnet is weak.Īnybody have the specs on these coils and magnets? Would have to be similar to Bulle clocks. With 6V, the clock runs, which tells me that the clock works up to the coil. With the pulse making it to the coil, this tells me that the clock is working up to the coil. The LED turns on when the ground pulse from the clock's contact sends the ground to the coil, which activates the coil (since the coil always has + to it). ![]() + end of of the LED is hooked up to the + side of the battery, the - end of of the LED is hooked up to the - side of the coil. I'm observing the contacts of the clock.īattery is hooked up to run the clock. LED test light is 1.5V LED bulb with some lead wires. ![]() I do get the coil to move the compass needle a little bit with 1.5V applied to it (with the magnet removed).
