Help, It's Dead...

Discussion in 'Technical Help' started by David Duke, Oct 9, 2021.

  1. Plugged in an extension cable and got a bit of a spark, not realising it was connected to the battery charger and that was already connected to the bike (ST2). Disconnected everything and turned the ignition on and found it to be dead. Assumed I'd knocked out a fuse so checked those (after checking kill switch), but found all OK. No idea where to look next, are there additional fuses, other than those by headstock and under seat?
    Thanks.
     
  2. If you’ve checked fuse the fear would be it’s the ecu? Eek!
     
  3. I don’t have an ST2 so it may be different to my bikes, but most Ducatis of that era have a big (physically and amp rating) fuse nestled on its own next to the battery. I would think this is the most likely culprit.

  4. I have to say my understanding of the electrical layout we have in Ducatis means you could plug it into the mains and it could not reach the ecu unless the key was in and in run position, but I’m open to be corrected on that.
     
  5. Yes, it's a 30 fuse mounted above the starter solenoid in front of the battery. It protects the regulator in the event of a reversed connection and isolates the bike from the battery. I've seen this happen a few times. Usually the bike is OK - but not always.

  6. I once jump started my 916 from my car with the leads inadvertently reversed. The battery literally exploded and showered me with acid.
    ECU was fine though, no blown fuses or anything.
    New battery, started first time.

    Hope yours is just a fuse.

  7. From your headline I thought you were talking about your parrot. I was going to say, are you sure it's not sleeping?

  8. David, have you checked you have voltage at the battery. If the charger was left connected without being plugged in it is feasible (with some chargers or a malfunctioning charger) that it has completely drained the battery.
     
  9. This will sound stupid, but it's happened to me.
    Are you sure you haven't knocked the kill switch by accident?
     
  10. Excellent! You were right, it was just sleeping (seems battery charger had drained battery having remained connected)

  11. Thanks DTD, that appears to be exactly what happened. After several days it seems to be holding its charge.
