Temp Guage issues

RedFish,
the only 12V wire I have found goes to the Amp guage and it is not linked to the other guages on the cicuit board. so I guess I might have a wiring issues, also as mentioned earlier my circuit board has a section of the metal stripe that has seperated from the board it is not broken just seperated have you messed with this and if so what can I do to secure the metal back to the board.
Thanks
