I'm wondering after reading Alex's post about a faulty DCDS Motor driver, could it be a systemic issue?
And is going further and removing the shell beyond the owner's expertise?
Where is the best economical place to send the engine for repair?
If removing a basic engine shell is beyond the capability of the owner (required for basic maintenance), I would say it is best to acquaint yourself with the LHS tech.
Modular Lionel are pretty easy. No harness to deal with, Just pull off the R2LC and swap another on. The DCDR is also pretty bullet proof and not hard to swap. Assuming this basic TMCC Hudson doesn't have cruise. It is a simple device.
The flickering head light makes it sound like a sensitivity issue. Especially since he implied it runs in conventional. G
Reading between the lines, it would appear the owner has opened up the shell, or how could he have properly" checked the antenna " ?. Either way, it still warrants another look see inside. I've run across 2 instances of factory foul ups from pinched antenna wires that took time to work their way bare and ground out. I've also caused the same issue by reassembling without neatly tucking the wire(s)out of the way. Same symptoms.
