Lionchief + does not run

16  volts might be a little low and causing your issue. I can’t run my LC+ Berk on less than 18v without issues

Once you’ve exhausted every possible solution and still no success then I would return it to Trainworld. They are reputable and will take care of you. You don’t need the hassle.

This may be too simple, but relevant if you've never had a LC+ loco. There is a switch on the loco that determines whether the loco operates in command (LionChief remote/universal remote/bluetooth) or conventional mode. Make sure it's in conventional mode if that's what you are using, and in LionChief mode if you are using the remote.  16 volts should be enough in either mode.

Thanks for replies. I know of the switch between remote/transformer and have tried it in both modes to no effect. It appears my best bet is to return it to Trainworld. You guys are great.

DocMckay, I just came on this thread and am glad to see you already have the Forum input you need.

You may already know what I'm about to say, especially if you have other LC+ engines. From my experience, when an LC+ engine is in remote mode and running at 16 volts, the engine will run fine, but its smoke production may be substantially less than it would be at 18 volts. 

Good luck with getting it taken care of ASAP by Trainworld. Arnold

My vote is return it.   You do not need the hassle.

I agree. Return it for an exchange. If the replacement exhibits the same behavior, then look elsewhere for the cause.

Curious, I can’t think of any O gauge transformer that outputs no more than 16 volts. What are you using?

It's a Lionel type 1033. I said 80 Watts - it's actually 90. But has 8 volt, 12 volt, and 16 volt terminal combinations.

Yep. That makes sense. I thought you meant a modern 80-watt transformer.

I usually run all of my TMCC, Legacy and LionChief stuff at about 15 or 16 volts, so that shouldn’t be the problem. (Eighteen volts is the recommended maximum, not the minimum, for command control operations.)
