Several weeks ago I decided to just jump in with both hands and attempt to repair the power and relay boards from my latest purchase, a third CR-2020. I figured with the excellent expertise available here on AK it should be a piece of cake. Using Echo Wars’ excellent tools guide I have purchased a few items. Weller WESD51 Soldering Station, Hakko 808 desoldering gun kit, helping hands Octopus Clamp Kit, digital multimeter with mini-grabber leads, 170 side cutter, 6” digital caliper and clamping magnifier workbench lamp.
So today I received the newly fabricated boards, see attached picture. I don’t have a lot of extra time to devote to this project so progress will probably take several weeks if not a couple of months. I will begin the process of transferring components along with the pertinent service bulletins for these boards just as soon as the service manual which I ordered from Mike arrives. In the meantime I have a couple of quick questions. The fabrication really looks nice except that I need to trim them as indicated by the red lines shown in the picture in order to maintain the proper mounting and alignment. Also I will need to “notch” the power board for the two mounting brackets. Any suggestions of how to best accomplish these two tasks would be greatly appreciated.
