Thanks, Larry!
The #380 didn't work at all when I started reconditioning it, so I recently finished cleaning, lubricating, re-soldering and insulating all the wiring with shrink 'tubes'. It ran for a while, but the reversing was very 'sluggish' and about 5 minutes later, it went dead again. The transformer now 'breaks' when the loco is on the track, but is OK when I remove the engine; so there is a short somewhere. I will go back and look at everything again, and carefully check the pickups. And I really appreciate the 'number' for the reversing unit, I couldn't find that anywhere.
Thanks again, John
