    Default Burned out circuit racer circuit board fully restored. Schematic included

    Hello,

    I just finished restoring my second circuit racer. When it arrived the circuit board was toast. I decided to locate all the parts and create a schematic for anyone who may have a fried board. I plan to make a rev 2 with photos and a current BOM. I found locating equivalent parts from the 70s took a bit and really is 90% of the battle.

    In the mean time the schematic should be good. Please don't beat me up to bad.

    I ended up not wanting to wait for a new holding magnet for the ratchet wheel so I rigged a solenoid in its place. The first holding magnet fit perfect, but was to wimpy and my stronger one won't arrive for another few weeks from China.

    Well so much for uploading a nice PDF of the schematic. Doubt anyone can read that shi%. WHY CAN'T WE UPLOAD A PDF THAT IS RIDICULES

    PM me if you want a clean copy of the schematic. of course the PM won't let me upload PDF OR pics for that matter. I'll have to send it to you via a normal email account. Deep breath deep breath

    Sorry for losing it in the last post I nearly had a brain hemorrhage. Ok I tried converting the PDF to a high quality JPG. It looks readable if you zoom in. If not let me know
