I am refurbishing a used ZW transformer. It had a bad cord, one bad ground terminal and no light bulbs. I replaced all the bad components and tested the functionality. All throttle and voltage controls work as expected including whistle and direction. The only issue is that the red bulb (left side) does not light. Swapping the bulbs proves both bulbs are good. I do not see any bare, shorted or open wires. Does anyone have suggestions as to what might be amiss.
Thanks,
Mike
