Shorts in Legacy engine

When you say shorting out do you actually see any sparks from the wheels or does the engine just stop. Check the rollers and also check if there is any arching marks on the underside of the engine. There’s a good chance no damage has been done to any boards.

I have a Lionel legacy Mohawk from 2022 that all of a sudden is shorting out.  I haven't taken apart yet to look for damaged wires or something to that effect but I have a question. If I have a damaged board what are alternatives. Is it true that legacy boards are no longer available. Does this $1600 engine beome a paper weight or are there alternatives like ERR or some other

You're panicking before you have any facts, take a deep breath.  I'd find out what is the cause before throwing in the towel.

Rod. Thanks for replying.   The transformer trips as soon as power is applied

John thanks for replying. I'll try not to panic about most expensive engine on layout.  I was interested any way on question about legacy boards and alternatives

Boards for a 2022 Legacy engine should still be available.

Thanks to all who have replied. I have not determined problem yet but I have found that the board for my engine is listed as available at Lionel for $190. Given that I invested $1600 on engine initially I am tempted to just order the board now and have a spare ready even if current problem lies outside of board. Does anyone know if these boards are interchangeable with other legacy engines. Would this board likely work with another legacy engine from same year like the Pacific I purchased same year for $1500

last question  if I remove AC input to board and still have a short would this eliminate board shorts as culprit

If you unplug all the connectors from the board and still have the short, it's certainly not the board.   I'd save your money, the odds on the board going aren't that great, do you really want $200 tied up in something that lines your closet?

Thanks John. Would pulling just the AC in quickly  isolated all boards from issue ?  I don't really want to have 200 tied up but it might not be bad insurance  as backup for two engines I have invested $3000 and maybe more in future. Or am overly concerned about future availability of boards?
