@Jon G posted:These boards have a problem where the solder pads on the voltage regulator are too close together and short. Usually the LEDs are OK (I just repaired two in the last week); test them with a 9v battery and 220 ohm resistor. Direct replacement boards are not available, but we use the 6v lighting kit for dummy A-Units, remove the jumpers, cut a trace and move the resistor over from the bad board. Part number AG-0000016. You must have about 100 ohms between the volt reg output and the connector for the LEDs, or you didn't cut the trace on the board and will burn up the LEDs.
I was investigating the A0000016 board. Is this the 6v light kit for the dummy A-units you mention ?
A0000016 is offered on the MTH site as a substitute for similar boards no longer available including the Stage Boxcar. The resistor is omitted and replaced by a jumper on this board.
Do your 100 ohm resistor. and cut the trace modifications apply to the A0000016? What trace do I need to cut ? What jumpers do I need to remove ?
