Short Circut 4 180 bricks

[Anonymous]

Hi Gang;

I have four 180 bricks on a new ZW for four blocks. The Main line is "A" and the others are for blocks and accessories.

When I derail on A the power goes off to the other three. Yet when I derail on any of the other three only the power to that brick goes off.

Everything is phased properly and I use a common buss ground for the 10 x 30 layout.

Any suggestions????????

Your instruction book says that you must supply power to the A terminals. This is essential since the internal circuits derive their power from this A input, making things a bit different for the A vs. B,C &D.
