Sent: Tuesday, December 1, 2009 18:19:36 From: David Davis (vorblesnak@gmail.com) I have been handed an ETX 70 EC to repair, maybe buy. It took me a while to get into the scope, the bottom plate screws were under the rubber feet. I think I fixed most of the issues but there is no connection between the battery case in the bottom of the scope body and any of the boards. I suspect someone has been into the scope before .. or Meade has very poor quality control. Can you point me to a picture, a schematic, something that might tell me where to connect the battery wires to the circuit board? Seems like a nice little scope. David Davis Toledo, OR 97391 And: Bob Hudgens down in Texas had a working ETX 70EC and he popped the bottom cover off and took a picture of the connection for me. I will send you that picture if you like. The wires connect to the board that holds the switch and the AC adapter socket. With the cover off of the base and the switch facing away from you, the Azimuth drive assembly is on the right. There is a mounting screw for the motor assembly right next to the board near the right end. Just above that screw are two solder connections. That is where the battery hooks in. The black wire hooks to the right solder joint, the red to the left solder joint. Many thanks again to Bob Hudgens. David Davis |
