I have voltage at 11.9v on pin 1, 4.7v on pin 16, 4.7v on pin 18. Would that not show my module is faulty?
 
Hi Mike,

Sorry for the delay in getting back to you again!
So i now have the Pin Out for the connector on the Bluetooth module. Hopefully this will give you more insight on what connections there are.

I also have a spare Bluetooth module if yours is faulty.

Hi it's okay for the delay. As I said in the post above I have voltage on 3 of the pins of the plug that plugs into the module.
