Capcom Trough Emitter Board
The original boards use three parallel LED and resistor circuits. The resistors are located so that they heat the LEDs. Net result, failure within the service life. This redesign puts the LEDs in series, cutting power buy about 60 percent. A visual indicator shows current flow through the LEDs, and a second indicator shows presence of 12V at the board. This is a useful diagnostic indicator for system power.
