the metal tab on the E unit that comes threw the top of the engine casting should be able to be moved with you're finger easily but you do not want the tab to wiggle or be loose or you won't make contact and the E unit won't work. you should hear a click sound when you push the direction button on the transformer. good luck alan Originally Posted by GG-1fan:
I have a Lionel postwar Berkshire that was running well until last week when it refused to go forward or backward. I took it into a repair shop.

All of a sudden when I tried to start it up again today, it failed to work again. Just out of curiosity, is there anything in the voltage from the transformer or track system (ie. shorts) that could cause a malfunction in the E-unit?
