Power Pack Rebuild part 4 add a power on off light

Using a bridge rectifier and an LED panel light with resistor, the MRC 402 Ampack can show you when the power is on or off at a glance. Very easy feature to add. We also added some vinyl non-slip feet to the bottom of the case that doesn't just prevent slipping, but also allows us to safely set the unit on top of live track without shorting the track.
