Power supply draws big amps and Ezcan cuts it out.

Question

Hi Guys, I have an issue and I'm not sure what to do about it. &#010;&#010;Today I started installing the Innovv K2 on my BMW, I got it second hand but it is in excellent condition and works. I tested it with USB and on 12 volt.&#010;&#010;However I think there is an issue with the Innovv power supply (old model without indicator light).&#010;&#010;I've connected it to my Hex Ezcan and here the problem occurs, the Ezcan keeps cutting out (when set at 2 amps) the Innovv and starts flashing red (over-load). I checked with the laptop connected and it indeed does draw a huge amount of amps on startup. Anywhere from 5 to 29 amps according to the Ezcan. Once it did start up, probably because I upped the amp threshold in the Ezcan, and it works fine and is only drawing about 0.6 amps when on.&#010;&#010;The problem is in the startup and I'm at a loss?!&#010;&#010;The power converter is of the old type without a indicator light, is this a known issue with these?&#010;Best option would be to get a new converter but I would like to be sure that is the solution.&#010;I could wire it directly to the battery but then I would most likely have the draining issue......&#010;&#010;I hope you guys can shed some light on this issue....&#010;&#010;Thanks&#010;&#010;Martijn

I don't know which model BMW you drive, but on the K1600 you have a round connector under the passenger's seat. This is intended to connect the topcase. This connector contains a switched power supply. It is the red / yellow wire. After the ignition has been switched off, voltage remains at this connection for 60 seconds.If you connect the yellow wire of the K2 to this and connect the power cables directly to your battery, then I think you have an interference-free power supply for your K2.

Hi MartijnDid you find a solution?I experienced exactly the same today switching my k2 to my newer bike, purchased a Ezcan and used this to install k2, exactly the same proble as you, once the k2 did start it was fine but would red error on restart, very interested if newer power supply helped?thanks, Jim

Hi,For this specific problem I got a new power supply. However in another post, which I have yet to replay to again, I describe the same problem you have. My K2 was connected to the EzCan on the yellow circuit to the stripped switched wire. It worked fine for over a year. Then the K2 suddenly didn't power on any more after I installed a new battery. So I did my measurement and to my big surprise the EzCan has changed wires. So I de-soldered it an re-soldered it to the yellow wire which was now suddenly the switched wire. I have no idea why the EzCan has done this and I hope it doesn't again.

Now however its starts a full charging cycle every so often indicating it has fallen up to 25% in charge.....it never did that before I connected the power supply to the battery.Yep. The old power module takes around 1Ah/day. And since normal motorcycle batteries usually have around 8-12Ah, they will get discharged quite quickly.

Well things seem to be sorted. I will receive a new power supply. I did however connect the old power supply directly to the battery with the Ezcan as a switched wire. And I do have a power drain issue. I have my bike on a Noco genius smart charger and over the winter it is always green when it has charged and it keeps it healty with a trickle charge. Now however its starts a full charging cycle every so often indicating it has fallen up to 25% in charge.....it never did that before I connected the power supply to the battery. New power supply should be here i about 3 weeks so untill then I will keep it like this and continue installing everything I want connected to the Ezcan on the bike.
