yes something is wrong somewhere, ive just soldered the 510 when checking with a meter earth and 510 pin no fire button pressed im getting voltage of 3.2v then press the fire button and no change,
Ok it looks like im gonna have to pull it all out and see whats happening, Hopefully i notice something this has totally baffelled me.
Thankyou both @dwcraig1 @Wayneo for your time and patience i will start testing connection when i get a bit more time and hopefully have a good outcome
