Hey guys. I have a two battery (electric boat) that uses a REC master and two slaves. There are no LED lights anywhere even though the master has 61VDC. Desperate, I took apart the master and discovered fried parts close to the input power leads. I need to fix this ASAP but I need to know what values these items are. It appears that the blown component (which blackened the area) is close to "C31"... I also noticed a "D2", a diode, but I really don't see a typical diode. I'm going to take it to an electronics shop but what are these items? Does anybody have a schematic of these items close to Vcc in? Also, it looks like this master has been previously repaired which gives me lingering doubts. Thanks!
