Started 2020 with two disassembled/non functional Sun 1020 to maintain my classic cars.
After some investigation and a lot of work one 1020 was alive again.
To get some missing accessories I bought another 745…
In the meantime the second „donor“ 1020 works 95% too and is used as decoration in my garage.
These mid 1960’s machines have point to point wiring, in the meantime I have wiring diagrams and calibration manuals for the 1020, but they work for the smaller like the 745, too.
Last summer I found just the modules from a 1120…
This week I found time to take care for them. Everything but the dwell works after some hours. The moduls look similar outside but now everything is done with PCB‘s inside.
Just found the link for sun repair manuals here…great.
