Dealing with a tempermental trackspot

Ok, apparently someone made this light mad. First thing was Vreg2 was missing. I replaced it and it was really mad lights blinking, motors shaking, followed by a little smoke from somewhere around C42. I quickly unplugged it. Apparently that missing Vreg2 was replaced into the home of Vreg1. So I got that fixed. Its happier now, but what is happening is the fan is not turning on, and the fan led is barely glowing, followed by the famous error tone. I do not get the error when all the dip switches are off, but when i put it in self test I do. Is this due to something going on with the fan circuit. I am guessing all of the chips may have seen 12 V down the 5V line due to the vreg being in the wrong place. Any ideas. The wheels do home correctly.

BTW the board is the red one V1.5 with the V2.1 Eprom. Also does someone have a link to the older bin files so i can install version 2.5.

After further investigation, the Fan light comes on like normal if i unplug the fan but if i plug the fan back in it dims down to almost being out. The fan being connected or disconnected does not make a difference in the error tone.

    Also, do you have a lightwave controller (Universal, Trackspot, or Intellabeam all work for the trackspot)? If so, try seeing if it responds to that.

    The reason I ask, is with all switches off, it should be in Lightwave mode (and you've implied that it doesn't make the error tone with all the personality switches off). If it works in lightwave mode, that implies the fixture in general works, and it's probably an issue with the dipswitch circuit, probably related to switch 1, since that's the switch you change to switch between Lightwave mode and Self-Test mode. If that switch alone were bad, though, it wouldn't error, since it would be stuck in Lightwave mode, so it must be something like it's shorted to another switch, which would put it in an invalid mode.

    Also, when checking the dipswitches, don't get confused that the sense of switch 8 is opposite the other 7 switches. That one threw me for a loop for awhile.
