Lionel C420 cab light problem | O Gauge Railroading On Line Forum

BillbarmanOGR Forum Member

I purchased a Lionel NLOE C420 on Ebay back in December. It's ran fine until just recently. No matter what I do the cab lights in the engine flicker, both in TMCC and conventional modes. It seems to run fine and still goes through the directional cycle, but the cab lights won't stop flashing.

I actually figured out this problem stops when I turn the smoke unit off. I have no idea why, but turning it off causes the lights to return to normal and only change depending on if the engine is moving or in neutral.

Has anyone had this problem before? Any idea how to fix it?

Read the manual. It is alerting you to a smoke unit issue. There is a pattern.

I would have, but the seller included the incorrect instructions with the locomotive and box so I didn't have them on hand. Thanks though.

What is the pattern?

2 blinks would be the smoke element, 3 blinks is a fan problem.

Here is a Legacy C420 manual.

Top suspect will be the smoke unit fan, I'd bet nickles that it's three blinks.
