Water Flow Indicator Problem

Discussion in 'Technical Help' started by PeterT, Aug 29, 2018.

  1. i bought some cheap yes Chinese water flow indicators which move like the Audi car versions, they were dirt cheap and suit my requirements for the time being as I will be putting Rizoma or Kellerman units on when I get my tail tidy fully sorted to clear my panniers on my Multi. They have integrated resistors built in and work directly connected to a 12 volt battery, however when fitted they only sweep once and then the can bus system can’t recognise them again as they momentarily go of to start the sweep again. Is there any way that I can fool the system? As they look rather smart and cost me £2 each which is a bargain.
     
  2. What year is your Multi? I don't know about the DVT models but for previous years the front indicators are driven directly from the dash and the rear ones from the BBS with the Canbus carrying the signal between the two units. My 2010 happily accepted LED rear indicators with no resistors and everything worked fine but if one of them was disconnected or a rear bulb was blown the corresponding front indicator flashed at twice speed.
     
  3. Have you tried asking the company you bought them from? Hoping some one else had the same issue?
     
  4. Forgive my lack of specific knowledge but back to first principles, if your cascade indicator light unit works when directly connected to a 12v power supply, doesn't that indicate (no pun intended) the unit has an integrated relay ? Not sure how 2 relays in series would work which might be your problem. Andy

  5. Normal LED indicators work no problem as I have tried those, even with resistors connected
     
  6. Are you saying that the relay only powers the rear units as original ones were bulb but the front ones located in the hand guards are LED
     
  7. Not any chance of useful information coming from them really,
     
  8. Which implies that they will require a continuous 12V supply (while indicator is selected) to work, not an intermittent on/off supply from the dash, or flasher relay if there was one.
     
  9. Yes I agree it obviously gets the supply as the indicators are switched then they work, but how can I retain current draw?
    Can I use another resistors to do this I wonder
     
  10. The 12V is "flashed" by the BBS ecu over the CAN network. The cascade indicators will be getting a pulsed 12v supply hence they only work once. No way I can see of them working in truth and I'd be very cautious connecting a second 12V as it could/will feed back into the ecu.
