I pulled this engine:

http://www.lionel.com/products/chessie-system-lionchieftm-plus-2-8-2-mikado-2103-6-81299/

out of storage and its dead as a door knob. It worked about two years back and then a bit of transportation happened.

If I apply power, nothing happens. No beeps, no lights nothing. Changing the transformer switch does not alter behavior. The LionChief remote blinks fast after a few seconds when the remote is turned on.

I took off the body and probed the CN1 terminals on the top PCB. I measure 18 volts on the CN1 terminals on the top PCB. I think this is the main power input to this top PCB.

The PCB has power.  I do not know how to debug this thing any further though. Is there a service manual with other probe points?

Also, it seems like this top PCB has a bit of white discoloration on the right side as shown in the picture:



Does this look like anything diagnostic?
