Here's the latest: I am beginning to think the problem is more mechanical than electrical. I put the unit back on the track this evening, and nudged the fan motor with a toothpick to encourage revolutions for the chuffs. Low and behold, the fan revolved, but only for a few chuffs. Then it gave a slight movement in the direction of turning, but only a nudge. Continued gentle prodding with the toothpick had the same results - few successful puffs of smoke (3-5), then stopped turning. This is interesting b/c the motor turns continuously when I apply external power with a 1.5v battery. Not sluggish at all.
So here are a few questions before I take any more steps:
The posts above suggest a drop of oil or Eliminator smoke fluid. Is one recommended over the other?
Should either go directly into the opening above the fan motor or should I open up the smoke chamber?
To open the smoke chamber, just remove the 3 philips screws on the top? See attached photo.
Is there a seal on the top piece?
BTW, the smoke chamber was quite hot after the toothpick scenario. Is this normal for these units?
As always, thanks for any advice. Getting there...
Michael
