    Exclamation Driver 2HSS86H got Alarm. The resistor is broken.

    Hello guys.

    Last week my machine got a problem stopped working.
    I got the problem, it was the Driver: 2HSS86H Hybrid Step Servo.

    I opened the Driver and got four burned resistor with weird color.

    I'm trying to know how much Ohms are they.
    The color is "BLACK BROWN SILVER RED RED", but some tables says that resistor don't start using "Black" color, so, I have no idea if I should read the resistor from backside.
    I tried to take another Driver that is working to measure it using a multimeter, but the result is too small, I think I don't know how to read and test it.

    If someone could help me, I would like to change them to try to survive this Driver again.

    About I using the multimeter, can I measure this resistor at the board like I made? Or the Resistor should take off? (like cut off 1 side?)

    The Working Driver, and the BAD Driver.

    Well. I got 2.28K from this?>

    Edit:
    Now I'm leaning towards a 0.22ohm 1%.

    Seems black isn't an actual colour in the lists for a 5th band according to most of the calculators I've looked at.

    Just get a new driver. There must be an issue somewhere.
