So Yendor, disconnecting the battery should affectedly do that to the system, shouldnt it?

Well, I went back out in the dark just now to disconnect the battery again. What i found was the red arc SBI12 dual battery solenoid was still glowing on top, that meant the second battery was still connected and powering the the mains cables.

This time I took both off, and has reset itself. The dash 'sub tank' has gone out.

Rooky Error right there.....
