Hello again. After being out of S gauge for about 14 years, I am digging into my collection and getting things running again.
I bought the new Northern 6-48047 when Lionel introduced it, but have not run it until now. Boy, what a set of disappointments, one after another.
Anyway, the loco has one of the new E-units that Lionel developed for starter sets. It's the long narrow one with the slot in the board that usually accepts the mono heat sink.
The loco seems to run OK by itself, if you can ignore the loud squeak from the puffer, but the problem is that it has no high speed. Low speed performance is poor, to say the least, but even with 18 volts on the track, the loco hardly gets out of its own way and has very poor pulling power, especially for what it should have with that nice can motor in it.
I looked at motor binding and lubrication issues and there seems to be none.
Upon disconnecting the E-unit and running the motor on straight DC, it runs fast and strong, like it should.
So my question is... does the starter set E-unit have some sort of speed reduction built into it? Do these E-units go bad in such a way as to cause the motor to run slower than full speed? Is there a resistor value fix or anything of that nature for these E-units?
I know I can get out my old o-scope and poke around, but someone must know the answer here.
Thanks in advance for any help you can give. This loco is a dog right now, but it seems like it shouldn't have to be.
