Did I fry something?
MS3 and MS3X, home-built, with all the help of this thread.
Here's the problem: While testing the alternator circuit, I didn't remove the daughterboards, and now I can't get the MS to do anything. When I plug it into the computer, it recognizes the USB-serial converter, but I get no response at all from the MS, either on the stim or in the car.
It worked before I started (except the alternator circuit), but now it does not. I don't know where to start trying to figure out what's wrong. I've got 5v at all the proper pins on the main board when connected to the stim.

I'm out of ideas. I have no idea how to test a board I didn't build when it won't connect to the computer. Does anybody have any suggestions on how to determine which board the problem may be on? I can only assume I fried something by applying too many volts, but I just hope I only fried one thing instead of all three or something.
