Power supply draws big amps and Ezcan cuts it out.

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.

@Steve Bendall Thanks for our help. I guess wiring it direct is the only option. If I get offered a new power supply I will try it one more time through the Ezcan. Should work as per example in the linked video which was released a few days ago. In any case it would be good service of Innovv to replace my power supply.

@leroi50 I think you are missing my point - regardless of power module version it should not be powered through the ezCan, but direct to the battery and only taking the yellow delayed power through the ezCan (or gif that matter ignoring ezCan completely and taking the delayed switch from another bike source)

@Steve Bendall No I do get your point and this would be my next and only other way of wiring it. However it should be possible to wire it over the Ezcan, Innovv says so them self. Innova Wiring Step-by-Step (shopify.com) It is for the Cansmart, but thats a Ezcan rebranded Denali.

But I still worry about battery drain when connected straight to the battery. I hope Innovv replaces my old type power supply.

Hi Martijn,

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.

I never noticed such a huge power draw by the power module when I tested it on my regulated power supply. The 5-29 amps your Ezcan notice can only be a very short spike when the capacitors of the power module gets charged. Maybe the display of my power supply is simply too sluggish to show the short spike and your Ezcan is very sensitive.

So the huge draw when connecting the power module to power does not necessarily mean that it is faulty. But maybe a new version has a reduced spike.

As you bought it second hand, I don't know whether Innovv will replace it or not. But as your version has the power drain issue, they should in my eyes.

I would suggest to send a mail to Innovv (help@innovv.com) , explaining your problem and asking them to replace the power module

@Frostie The spike is indeed very very short, the Ezcan lists the amps it got when it tripped. It was anywhere from 5 to 29 amps the times I tried. A old fashioned fuse will not burn through with such a short spike...the 1 amp fuse in the + wire didn't anyway. But a electronic fuse will trip straight away. Indeed very sensitive! I hope Innovv will replace my power supply free of charge anyway.

Hi Steve, thanks! This would indeed be my next way to wire it. I read that the old type power supplies might give a power drain. But I will rewire it and see what happens. I can always fit a relay in between. Still surprises me, I’de have thought it would work over the Ezcan......

If any of you gups or gals have thoughts on it please let me know!?

Shouldn’t need a relay, set the exCan to act as an accessory circuit is all you should need. Where are you, you can talk with Innovv as they might upgrade you to the later power converter if you explain you still have the older version
