obviously you have some wire crossed straight to the positive side coming off the battery.. (probably before the ignition) trace the wire back from the speedo to make sure.. i recommend getting a wiring diagram to speed the process and make life simple...
you messed with any of the electrical?

This is a common problem with the Daytona's 2002+. Typically its the charging system and if the battery level gets below 12v the instrument panel will not function properly (LED display will read or flash something other than what is normal). Recommend charging the battery and checking the voltage @ the battery while running. If voltage drops as RPM increase: Replace reg/rect. The Stator my also go bad too. Too T/S (remove tail section disconnect the 3 wire connector coming from the stator and pin check a/c voltage across two pins at a time. check condition of connector and wires, if it feels stiff and brittle replace wire loom and check 3 pin connector under the fuel tank. If still bad, should be Approx 45v a/c @ idle, replace stator OR send it out for a re-wind. It's cheaper more durable and you get a 1 year warranty. I recommend Custom re-wind for this.
