Thank you Marco and Udo for responding.

I did try 9v 500mA and 9v 800mA adapters. Module still won't work. I did test the voltage internally from the socket without the modules. It shows 5.12v.

If the MM V requires 6 volts it looks like my Exclusive board which came with the Senator module (5v) can not handle it.

The ebay seller has no return policy so it looks like I am stuck with items I cant use.

All the best
