Hello, all knowing Zero88 people.
I'm trying to resurrect a Sirius 24. At first it was having issues with garbled displays all over the front panel, so I opened it up and reseated a few ribbon cables (some of which were so loose they fell out as soon as I touched them).
Whilst I had this open, I checked the battery, which gave a reading of 1.7v, so I'm guessing that I should probably replace this.
I also noticed that I couldn't see any DIP switches where the manual told me they should be. In fact, the board seemed to be a somewhat different design to the one in the manual. The battery was over on the right hand side of the board (with the desk upside down and the outputs pointing away from me), whereas the manual told me the battery should be near the back plate.
Now, having put the desk back together, the displays seem to make a lot more sense, but:
1. Output LEDs 1 - 20 are permanently on. 21-24 are permanently off.
2. If you put a meter between any output and 0v, you get 17v. I've tried setting the internal jumper to 10v and 15v output, and it makes no difference. Even if you flick the DBO switch, it carries on outputting 17v, even though one of the displays on the board has changed to say 'DBO'.
Anybody got any ideas?
Thanks, Huw
