So, I am new to this forum. I am not an electronics whiz. But, being in the HVAC trade for many years, I have limited electronics experience. Anyways, I have this Makita battery charger that quit working and upon closer inspection, there is an obvious diode or something that has shorted out on the board. Problem is, it's burnt so bad, I can't identify it. I tried researching the board Mfgr. for a schematic or diagram, to no avail. I think that if I were to replace it (I am able), I could probably make it operational. Thanks for any help!
