Two resistors in a Bosch AL 1115 CV battery charger 127V burned up yesterday, and I am trying to figure out the correct value to replace them.
I have found in the internet this photo where I suppose that these resistors are of the same value of that burned in my board:
This is a image of a similar board that I found on the internet:
This is a photo of my real board, that was burnt:
In that two resistors that burnt, in the similar board figure, I see the colors:
brown, white, red, red, black.
What is the value of this resistor?
I have learned that in 5 bands resistors, the first, second and third band are the value, the fourth id the multiplier and the fifth is the tolerance.
Black does not exist as a tolerance and in some five band resistors the third band is the multiplier, and not the fourth.
How do J know when take into account the third band as multiplier or the fourth band as multiplier?
What is the real value of the resistors in the figure?
