OK, so question 1, are the computers new from hotwire or is hotwire just sending you used computers? 2, have u tried calling hotwires tech support line? Getting 3 different problems with 3 different computers seems like a computer issue, although I have seen modules swapped out and have different symptoms to the same wiring problem. Now, my apologies for not understanding your lingo, but when u say there's no "earth" does that mean the computers not grounding the relays? Also what are the "ASD" relays? Finally, as with any high tech electronically controlled system involving computers and modules, grounds are extremely important!! Make sure everything is grounded, engine to frame, body to frame, even multiple locations of the body to frame. That being said, from what I can tell from your video, it looks like if those red lights on the gauge don't come on u know it won't start, and if they do come on you know it will fire right up? Is that correct?
