Hi I have taken two wires from 8136501 TO the LGb 51800 which controls track power and lights in points and houses and I then tried to take the power to my other LGg 51750 to control points..Ihave power as the green led light shows but the point switches dont work on the 51750 .all I want to do is use mascots to control trains dcc and use my original LGB boxes to control points and lights ,so I don’t understand why this is so complicated surely I should be able to just take the power from first box to second box also I have two wires going to points
Yes, it should be easy provided the power supplies are compatible. I'll google the Massoth and LGB units you have. The power light might show even if the voltage
is insufficient (an LED doesn't draw much current), but that does suggest you have wired the two units properly.
