Hey guys, i'm" proud" to be in teh 0020 BMS Isolation Fault !!    :-\ ;)

The bike: My brand new 2017 SR with powertank!!

No rain, did not washed the bike yet.. .. it only hapenned after the bike sitted for 2 hours on teh parking of a friend we visited me and my wife tonight. There was some moisture on the seat as well as  during the evening when the sun is down... but nothing more..

Everything work fine.. except that the red triangle flash in the dash...  It accept charging too...

I know BMS and electronic.. and alread read multiple thread here about that famous error 0020 and 0028...

But what is the final solution?.. well in average?...  clear teh code and hope that it does nopt happen again?  what is the most probable area /connnector etc where that low resistance  is usually?

I have parked the bike in my garage for teh night where  air is more dry... wel see tomorrow... the cell blalance is 5-6mV ( not perfect but not bad....

Yesterday when i got the bike at the dealer ( 250km from my home) the bike was in a trailer and we had intense rain during thunderstorm while i was driving the car at about 100kmh... I just hope that that simple/normal  event woudl not affect too much the Zero... as it is 100% normal situation that a motorcycle must tolerate.. the Zero was straped in a trailer  while driving and got some rain .. nothing more..

Dman it!! as you knwo i have the diagnostic kit that the dealer have.. so i connected to the OBD!! and got  the description:

That BMS isolation code error is described as:

Chassi Isolation Fault: 13kohms to cell 3 !!!!

Damn ! it look like it is even the BMS or the brick or monolith itself..  ::)

Bike is brand new! :(

But from now it is impossible to know if it is from the power tank or the Monolith...

Well i dont know how to condider it as 13 kohms isolation problem....


think about it:  at let say 3.8V nominal per cell  it is about 292uA leak current at 13000ohms so it would take about  56 years to fully drain the 145Ah total pack if fully charged... but might get worst as electrical corrosion can take place?

Last update: Chassis Isolation DANGER:    cell 3 droped from 13kohm to 2kohm!  ( 1.9mA current leak)

Damn... droped to 1 kohm... and then last error is 0 kohm...

not sure it is so low.. but it could be anywhwere between 999ohms and few ohms...

Sorry to read that, really. I saw how much you were looking forward to the new bike.

How is the warrenty for a bike DOA? Do they exchange it? (I fear not...)

I see chassis isolation faults all the time, but never that low. Also, my warning light does not come on...
Might give our Californian friends a call...

My guess, doctor, is that it's got a lot to do with the trailer ride home.  The only isolation error I've ever had on my 2014 DS was after I washed it.  I was pretty careful too.

I've ridden my bike through very heavy rain and it has a pretty hard life as a commuter bike.  All weather, all year.

My theory, and it is just a theory, is that the wind flow is different on your trailer.  There will be all kinds of different eddie currents hitting your bike. They could have concentrated the rain into something similar to a jetwash spray that found its way into areas that would never get wet under normal riding.

My advice is to simply let the bike dry out as much as possible.  Providing you aren't getting a massive cell  imbalance, ride it in the dry as much as you can.  Perhaps even drive it round on your trailer in the dry.

It may take a few days, but hopefully the water will leach out or evaporate from where it shouldn't be and everything will be fine.

Good luck!

UPDATE.

Good morning guys.. well dependent on where you are on earth actually =))

I had a conversation with the battery designer yesterday. He said that the indication of the cell 3 for the isolation fault is not necessary related to one of teh cells in the battery bt more like an interpretation of the voltage level of the isolatino fault. he said that cell 3 mean about 12V witch could probably related to the 12V line somewhere. the cell 3 of  all brick are all at the same voltage is at the level of 3 x the voltage of the cells witch is about 12V. It might be about the DC-DC connections near the aux port.

But he also suggested to disconnect the brown powertank connector and clear all possible water intrusion and see if i still get these errors.

The bike spent all the nigt in my dry garage with a 24" air blower at full speed directly pointing to all wiring  with the seat removed.. but i stil get the errors but i havent not reset these yet.

I also have sent the full report thru the Zero apps to the Zero service.

I will keep you updated on that .

Oh btw the bike still charge and is now 100% ( was 42% yesterday night)

OK i tried to reset teh BMS with each of the the 3 possibles combine ( Right button, watched if it clear the code: CODE 29 is cleared, Left button, Still code 20 and 28, Both at the same time:  Still code 20 and 28

So the Danger Isolation fault level cleared during the night Good..

Now code 20 adn 28 to go.....

Ok i connected the diagnostic tool and see actually that the famous "cell 3" isolation fault is now at 18kohm.. witch is good new

I will make a ride around here and hope that the hot wind will dry everything and get that resistance isolation to continu to go up

Keep us updated Doc!  I also have a powertank and sometimes would get a flashy dash after riding in the rain this past winter where it felt like it rained for 2 months straight.  But it never kept the bike from charging or riding and would usually go away after a couple days to dry out.  I would just assume water got in the powertank connector and like you said, formed a water bridge that could discharge the pack in 50 to 100 years if left like that so I never worried about it one bit.  But let us know if it doesn't go away in a couple days!  You need a Zero that is definitely perfect before you start adding your mods to it.  I can only imagine what it will look like in 2 years lol

You want some hot wind on it, bring it to Vegas. Going to be 110 degrees F here tomorrow, so, I guess around 43 of YOUR degrees.
