BMV 602S appears dead, what can I try?

I have bought a BMV 602S secondhand that has thusfar shown now sign of life. I have tested the shunt and the cable and both are OK (cable tested with cable-tester and shunt is giving out some values). However, the monitor shows no sign of live.

Any Idea of what I could try?

Bert where are you? Did you buy the unit with cables & shunt & instructions?

There should be a red wire with a very light fuse halfway along it. One end of it goes to the pos terminal of the battery & the other goes into the shunt. On the top of the shunt you should see where it plugs in? I tried to find the "quick start guide" but it doesn't appear on the site for the 602S. Are you sure it's a 602S? Was the 602 made in an "s" variety?
