So far it looks like you are in good shape. The Regulator is running. If you don't screw anything up your problem could be in the EEPROM. The other thing is the soldered joints in the tuner, yes this is one of those. These TOBs gave everyone problems. You should be able to find information on both these problems here on the net. Good luck
