CDU and 3 wire LGB points motor.

[Newby]

Has anyone wired a LGB 3 wire points motor with a capacitor discharge unit. If so could you share the wiring sequence please?

[Newby]

Are you selling them?

 

[sparky230]

I Have no idea what old 3 wire ones are worth

I also have 1 maybe 2 of this type should anybody wish to purchase. Will test them first though.

If I remember correctly the 3 terminal motors have a common return and the other two terminals are to throw the motor one way or the other. If so wire it is the way Peco point motors are wired: the return goes to the - terminal on the cdu and the two coil terminals go the the outer pins on a spdt switch. Wire the positive terminal of the cdu to the centre switch pin.

i've just checked one of the old ones i have, the centre is common , the outer terminals throw the motor one way or other
