This is a long shot, but make sure your power system is healthy from the battery wire issue (improper polarity Anderson Power Plug).

Have you drilled or machined near the DSC? The old ones are not conformally coated, and can short out if you get a little spec of metal in there.

When you mentioned "fixing" the cable, were you referring to moving it away from the protruding solder points or taping up damaged areas? If anything, try a new one on your next test. If it works, throw the old one out.

You might want to break out the multimeter and check everything for continuity. Are your fuses all correct? Have you made any wiring mistakes? Double check everything in accordance to the FIRST manual.

Do you have any BaneBot motors? If you had a BaneBot that was case shorted, for instance, you could have many mysterious electrical problems. If you do have a BaneBot, make sure you machine any OTS transmission to allow for air passages (most, if not all BaneBot issues are overheating related).
