ZR 580 with the battery. Was running great and then just died when we stopped for a break. Checked the ECU for any flashing codes and saw there wasn't any light at all when it was pulled over, Checked the fuse box and saw that the 3 amp fuse for the efi/ecu power was blown. Replaced it with another 3 amp fuse and it blew as soon as the key was turned on. Tried it with a 10 amp and then a 15 amp fuse and they all blew as soon as the key is turned on. I'm trying to find the short but not exactly sure where to look. What has power as soon as the key is turned to the on position? I know the fuel pump does, but where else should I look? Thanks in advance for any tips.
