Good morning, friends of mine, I thank you for giving me a minute of your time. At the moment I am repairing a treadmill, which the motor of the same does not work. Then I proceeded to disarm the machine and what was my surprise was to find a fuse burnt in the Circuit board to this apparently uncovered previously since they placed a bridge with a cable in the part of the fuse great error. then I proceeded to approve some components in which two scr s6025l is found in bad condition I say in bad condition because at the moment of doing the test with the multimeter this does not retain the circulation of the current between anode and cathode when I give the pulse for the Gatilla . I decided to do this test with a lamp and a push button and the scr does the same thing also is that at the time of testing with the multimeter between cathode and trigger the direct polarization leads and in reverse also and I understand that this should not circulate in reverse. My question is that if you can give me security of these faults. and if you can help me look for other possible faults as it has many components As buyers optocouplers tell me where I can find another item in bad condition thank you very much. <a href='http://www.subirimagenes.com/fondosycapturas-imag0356-9785767.html'><img src='http://s2.subirimagenes.com/fondosycapturas/previo/thump_9785767imag0356.jpg' alt="Upload images" border='0'></a>
