Hello from Spain,
I have just bought a 3013 NS analogic in good condition.
First trial everything OK.
I disassemble the body to reach the screws of the pantographs. I run the loko without the body, everything OK
But...when I assemble again the body and run it, it only goes in one direction. I try to switch, it tries but only a sound and doesn't move. I switch again and switches OK in the other direction. If I disassemble the body and try everything perfect.
I check the manual lever and apparently it doesn't interfere in this problem
Any idea?
Thanks in advance
Best regards

Thanks very much for the info. I will try again
Regards

Did you remove the light bulbs and holders from the body before putting it back on the chassis? or did you try to put the body back on with the light bulbs in place?

The light holders have to be put back in once the body is on the chassis. If you leave them in the body and then try to put it back on the chassis it can cause shorts because the bulbs are pushing downwards onto the contacts rather than pushing against the front of them.

The lighting on this loco is directional so if the bulbs are only causing a short at one end then the loco will run one way ok but not the other way.
If you did do this then I would suggest removing the body again and removing the light holders from each end of it. Check that the springy bulb contacts on the chassis aren't bent down and touching the chassis. Then put the body back on and finally slide in the bulbs with their holders and secure with the tiny screws.

I did this on a SET800 once and couldn't figure out what was wrong!

Thanks 60904
You are right. In mine only 2 positions.
