  1. My first post , but not my first Ducati.
    Nice to be here.
    Its an ST4S, which mates nicely with my MV Agusta F4 1000.
    I need help please.
    In a moment of brain fade just now I've put my battery in back to front and effectively reversed the polarity (wondered why the fan was running! - duh!)
    I've now replaced the blown 40amp fuse adjacent to the battery, checked all the others (all fine) along with other obvious issues.
    All electric functions appear to be working, lights, blinkers etc etc - except the starter motor!
    Are there any other fuses anywhere aside from the fuse block and the separate 40amp one?
    Any ideas what else I might have fried?
    Thanks all

  4. Hi and welcome to the Ducati forum from the other side of the world
     
  5. Its the ecu you need to worry about, you may well have fried it.
    Our resident ecu expert is @chrisw
    Is your fuel pump priming?

  6. Welcome Tony. :) :upyeah:

    You may not want to hear this, but my friend bought a new F4 1000 in 2010. He left it for a few weeks before using it and the battery went flat. He put a car booster charger on it and blew the whole ECU. o_O I hope you haven't suffered the same fate.
     
  7. Fuse 4 in the fuse box is a 3 amp for the ECU. Fuse 5 isa 7.5 amp for the key sense. Fuse 6 is a 20 amp for the injectors. Fuse 1 is a 30 amp for the main switch. Check them all. Voltage inversion normally fries an internal earth in the ECU. The work around is to run a wire from the earth wire of the diagnostic connector to the battery -ve. The diagnostic connector is a 3 way Superseal connector with 2 wires going into it. The earth is what would be the middle wire on the 3 way connector.
