Reply to "Need Help With 6-Volt Regulated Fan Driven Lionel Legacy Diesel Smoke Units and Boards -- UPDATED 2/6/20"

jpnrcOGR Forum Member SUPPORTING MEMBER

Gunrunner, once again your help proves invaluable! I tested the fan output of the PCBs on 2 of my engines that currently have their shells off and have properly operating 620-8265-200 smoke units. Both are putting out 5 volts DC. Then I test the 3 boards I just received from Lionel and all 3 are putting out 0 volts! So it seems that the TO-92 package 5V regulator (whatever that is) is bad on each board. Would you agree? If so, is there any fix other than a replacement board? Thanks again. John
