Hi Andy
I like those locos and mine is a 3013 from 1957. There are indestructible
Here is the wiring diagram that I modified to include the directional lighting (in blue and red)
The diagrams is owned by https://www.toottoot.co.nz/

Since in your case the relay switches over but no lights and no motor, one possibility is the drum of the relay is not connected to ground but the relay is.
Here is the "wippenrelais" used on your loco (left side of page)

Note that the drum has a screw to connect it to the axle and to the frame ground (see lower left of picture)

Other possible cause is a broken wire somewhere
Cheers & good luck with your repair

I have one of these. Does your's have the manual trigger for direction change? It should work as follows. Forward, Stop (with lights), Reverse, Stop (with lights), Forward... etc

In the meantime, try using the manual reverse tab to see if it changes anything. The relay may be stuck and using the manual knob may unblock it

Best regards

Hello Andy !
The problem may be on the directionswitch.It loks that the contactplate on top is bent up and therfor no contact for the motor.This is a common problem ,but it can be a problem to adjust it correct again.
You must be very careful by doing it,this thin metal will easily break.Maybe that this is the problem here.This contact is driven by the switch arm that goes in and out and lift the
contact arm (in center) on and off.Its this arm that is bent up.This solution was made for smother change of direction.

Best of luck kaav800
