Need a circuit diagram for a Ryobi BCL14181H charger to try and identify a burned out resistor

Contact Ryobi directly to request the diagram for model BCL14181H. Be sure to specify thr type of diagram you need.

I need to know which resistor are we looking for
mom control board next to component is #like R27 or C100
let me know which ones

Resistors R1, R2, R3, and R4 are arranged in a circuit as shown in the figure above. The direction of positive currents I1, I2, I3, and I4 through the resistors are shown. (i.e., negative current values correspond to currents in the opposite direction to that shown above). The values for the resistors and the batteries in the circuit are: R1 = 100 ?, R2 = 200 ?, R3 = 30 ?, R4 = 400 ?, V1 = 4 V, and V2 = 12 V.

Without a circuit diagram or another actual unit to look at it is very difficult to identify burnt out resistors. Even harder is finding out why it burnt out because most of the time a resistor only burns out if overloaded due to other circuit component faults.

You need to refer to the circuit diagram to identify the resistor and its value.
Most likely this resistor failed as a result of another component failing.

hi
the only way the transformer can burn out is : if transformer is asked higher output that is design for or if the insolation of the winding ( transformer ) is going or gone down

they are 2.2 ohm , i have replece many of this before

I have the same exact problem in a 12 volt Lincoln battery charger. Burned resistor in R5.

I need the same, but found a Makita multi-voltage charger and have been able to use it. The package says It is for Makita batteries only. HItachi also makes a universal battery charger. I found both at my local Lowe's. The Makita was originally $69, but was marked down to $25. The Hitachi was around $70. You can find either one for good prices on Ebay or Amazon.

Good luck!
