Hi David, For what it is worth I had a similar problem with a HK sourced adapter=20 - execpt it did not work at all. I was going to return it and had=20 emailed the seller until i cleaned the 'electronic contact' on the=20 adapter. It seems some glue (or something like resin) might have got=20 onto the contact area when the 'module' is attached and may have either=20 been an electrical insulator or possibly just caused a mechanical=20 tolerance problem - I had to scrape it off - cleaner would not move it.=20 It worked fine after that. Any sign of glue on the adapter you have?
