Autohelm Wiring Issue

When I bought my good old boat, it came with a Raymarine ST4000 autohelm. Wires (grounds, presumably) ran to the metal fuel tank. Probably not a great idea, but whatever. Last winter, I had to replace the tank as it sprang a leak and the yard guys put in a plastic tank.

Since then, the Autohelm doesn't work. Looking below, I saw wires dangling unattached, so I attached them to various screws that seemed to be used as grounds for other wires.

Now, when I turn on the Autohelm, instead of darkness and silence, the controller lights up with the correct compass heading, but when I engage it, I get a few clicks from the neighborhood of the wheel, but nothing else.

Anybody got any bright ideas?
