I have an old JRXP9303 that I habitually leave powered on and in doing so destroy the lipo transmitter battery. Is there a way to add an led light on this board? I dont have voltmeter/multimeter and I am wondering if someone can point out the positive negative wires that I need to solder an led and resistor on. I've recently upgraded this transmitter to 2.4ghz and would like to add an led in the hole now present from the old antenna so that I can see that the transmitter is on. Trying to find a way to visually help my bad memory!
