    Faulty treadmill control board

    ok the M+ and M- for the motor try to measure the output voltage with DMM and see if it's constant or it disconnect after while

    Faulty treadmill control board

    that caused of overload on the motor due to heavy running belt, i suggest you to lubricate the belt very well" between the belt and the underneath piece of wood " before assuming the fault in the circuit

    Is that a fuse or resistor

    So couldn't find fusible resistor in my city so I'll use 220V 1A glass fuse, couldn't find less than 1A or 10 ohm 3 watt carbon resistor Which of them would be better as protection?

    Is that a fuse or resistor

    ok i tested with the LED strip and it work fine, you were right it needed a load to work

    Is that a fuse or resistor

    i already connect the input after the fuse since i don't have the fuse installed on the noise were from the IC circuit not the AC line noise.that's why it keep getting slow on the radio till it fade out when i disconnect the AC power

    Is that a fuse or resistor

    No it's alright 400V 15μf 100V 22μf It's for 60V led light, I've tested with DMM and didn't get dc read I bought new LED string, but waiting to fix the power supply before I connect it I didn't put the lamp on the fuse place, I have it as AC in to the circuit so if there any short in the...

    Is that a fuse or resistor

    Ok changed the diodes, I'm hearing like buzz from the circuit but no output Dc while connecting to 60 wat lamp in series It's a led light Power supply by the way

    Is that a fuse or resistor

    Is that blown item is fuse or resistor, and is it possible to replace those SMD didoes with usual one?must the four bride SMD didoes be replaced or can i replace only two that is faulty with regular 1n4007

    measuring output current circuit ?

    maybe i couldn't explain what i were saying in better way.. that's the circuit i made to be able to test the current by the multimeter on the blue wire, so as you can see no D+,D- all what t can get is 5+ and gnd unless those are what tells the phone the amount of current the charger is able to...
