1199 Ignition Issue

Discussion in 'Technical Help' started by cm73, Jul 26, 2021.

  1. Morning, anyone come across an issue i have, basically my bike is staying live after switching off which is killing my battery. Bought a new battery and as soon as I connected this, the dash , fuel pump etc came alive, this with the keys in my pocket. Tried disconnecting the ignition switch and still the same, cannot see anything obvious.

    Bike still starts and runs fine, with the dash going off after running, but the new battery is still depleted in a few hours.

    Bike is running a rapid bike ecu if this makes any difference?. My usual dealer is flat out until september so if anyone has a long shot idea, please let me know.
     
  2. It could be worth disconnecting the battery negative lead and leaving it for around an hour. My understanding is that ECUs can retain current even if the ignition is off and it can take a while to properly discharge.

    It probably won't do anything but it's possibly worth a try.

    What you're describing is an open circuit fault, which is either a wiring break or a component failure. The likely contenders are a relay or ignition switch although in the modern era things can be an awful lot more complex than that, especially with an aftermarket ECU.
     
  3. On earlier bikes this symptom was caused by water ingress on the coil/injector/pump relay stopping it from disconnecting. Cured with a new 3 quid relay.

  4. Thanks for the reply, I did wonder if it might be water ingress as got caught out in the rain about a week prior to this happening, but had used the bike again since so dismissed that, maybe wrong to do so. I have disconnected the ignition switch and the issue still occurs, same with the rapidbike ecu. I can heard various relays come to life so guess a process of elimination.

    I am assuming there is an ignition relay, anyone know where the location of this is?.
     
  5. Here you go.

  6. The 1199 uses an E-lock system. I'm not entirely sure how it works but it is connected to the Canbus and lights up the immobiliser LED when the ignition is off. When the ignition is switched on it energises the E-lock relay which turns the bike on. First call would be to replace the E-lock relay. It is shown on the wiring diagram but unfortunately the manual I have makes no mention of it, perhaps for security reasons.
    There are 4 relays on the bike, the E-lock relay, the fuel pump relay and one each for the horizontal and vertical throttle control motors. They are mounted under the tank with 2 on each side of the air box. The wires to the E-relay are Red (live 12V from the battery), Red/White (relay out to the Fuseboxes), Red/Yellow (from the E-lock to energise the relay) and Black/Yellow (ground).
    Hopefully that will help you find the relay and help track down where the fault lies.
     
  7. @bettes just beat me to it and has shown the location.

  8. Thanks for the above, managed to borrow a multimeter yesterday and the drain is just over 2 amps, also removed the four relays mentioned, no change, removed fuses by the battery, no change, pulled apart all the connectors I can get too and again no change. Anyone have any ideas what can cause this, it's like leaving the lights on sized drain.

    Someone did mention the BBS unit, but not too sure how this would figure in with the dash?. I think it's a case of keep pulling apart connectors!!.
     
  9. I'd be pursuing the possibility of water ingress, if the bike was running fine prior to getting caught out in the rain.

    And primarily for the sake of maintaining the battery, remove it and put it on a trickle charger and that will allow any residual current to drain away.

    I realise you've removed the ECU but perhaps not for long enough, as the dash is also retaining current?

    It seems unlikely but you wanted long shots..

  10. The BBS hasn't got a permanent supply so I can't see it being the cause. It is connected to the dash, and just about everything else by the CANbus.
     

  11. Thanks for the reply, sadly i'm not too technically minded with regards to fault finding electrical issues, so just trying to work through things as a process of elimination.
     
  12. You and me both!

    Modern electronic systems on motorcycles have all the complexity of a smartphone or laptop and they're exposed to the elements.. It should be no surprise they have problems.

    Just another thought but is it worth pulling the multi pin connector for the dash itself? If that's got moisture in it, I'm sure that would cause all sorts of issues.
     
  13. Thanks, I'll try anything!!.
