20 Most Recent Lionel Cw 80 Transformer Questions & Answers

Looking at auction pictures, I'm going to say that odds are the fuse is located in the main unit. You can pick up those tamper proof screwdrivers at Harbor Freight pretty cheap. Please make sure that you've properly discharged the unit before attempting any repairs.

You can't. These transformers aren't user serviceable. You can thank the Federal Government for that. If you can find the special tool to remove the case, you'll be able to open the transformer. For service, contact Lionel customer service or take the transformer to a Lionel Service Center.

On the base of the transformer you will find 4 tamper proof screws that you will need to remove to open the case. A triangular blade screwdriver will be need to do this. Once removed the tamper proof screws can be replaced with self tapping screws.

This transformer is difficult to open unless you have the triangular security screw driver. Security bits can be purchased at any Harbor Freight tool store but you will need to adapt them to fit into the channels where the screws are recessed.
