What's the wiring look like - what's on what pin on the relay?  I ask
because I had 2 relays set up for the central locking on the sliding door,
and the first time I wired it up per the instructions I had, it was using
power all the time to hold the relay open, even though there was no current
needed.  I ended up basically swapping + for - on everything, and the
battery draw disappeared.  It sounds like you're doing something similar -
that's why the isolator clicks.

My setup is just using the fridge relay - that provides power when the
engine's running.
