2014 Brammo Empulse R not taking a charge

[KaFr]

Thank you very much for posting the photos after opening the battery module.
It seems that the water did not penetrate in larger quantities, but in several different places (the nut of the BMS connector and also the pole screw?).
Could you please add a more detailed photo of the RESET jumper?

I would like to help you, but I need the following information from you:
- Did you analyze the data from the flash drive? Did error B8 occur in addition to error B40?
- Did you measure the voltage of the individual cells of the module? What is the difference?
- After thoroughly removing the corrosion from the PCB board and reconnecting it, is the status LED still solid green?

BTW: another confirmation that this is module number 7 (the last module in the series) is a plastic plug on one of the BMS connectors.

Oof it looks like what was happening inside my motor cover, more stuff to damage inside the battery though.

I will post more pics of the reset jumper later today,

-I had issues opening the log converter files on my PC is there a way that i could send you the raw brammo files from the flash drive?
-I measured the voltage across the 4 cells and there was no deviation across them all four read 3.933 perfectly
-finally I will reinstall the module today to see if the BMS stays solid green i plan to post more findings today
Confirmation: Yes this is #7 module with the terminator bms plug at the end.

Of course, I can help you analyze the data.
What is the total size of the data on the flash drive?
Can you share the data via dropbox.com or something like that?

[invoke performance]

the total size is 1.5gb do you have a dropbox account ! can send it to?

the total size is 1.5gb do you have a dropbox account I can send it to?

or would i be easier to email?

[KaFr]

Yes, I have a dropbox account. Due to the large amount of data, the only option will be the dropbox. My email in PM.

I have just analyzed the data and there are the following serious errors:
A6  : AIM Module Not Responding
B7  : Battery Fault: Module Lost
B8  : Battery Fault: Temperature Sensor Failure
B32  : Battery Fault: Sanity Error (No communication)
B40  : BMS Back in Idle Mode

There are also the following warnings:
B55  : Battery Fault: SOC Mismatch > 30%
B64  : Battery Fault: 300A Over Current Warning
COME TO FULL STOP : Vehicle Speed not zero when throttle switch was turned on

The following errors are probably caused by disconnecting the cables:
DASH OFF - NO MESSAGE : Dash CAN Processor Failure
V69  : SPI Flash Memory Failure
V78  : Real Time Clock Not Working

I'll send you the exported files so you can take a closer look.

Thanks I will look at the logs! here are the close ups of the module reset jumper.

Thanks for the very illustrative photos. I think resetting the battery will be easy.

No problem!  Today I reinstalled the module on the bike after the corrosion clean and got the same B40 condition. So it seems that it will need a reset of some sort. So I will await your ideas on how to reset the BMS board thanks. My best guess is to completely complete the HV side circuit with all modules present with the cover off, three way current shunt connected, and then connect the BMS connector to energize the the PCB as normal.  Finally connect a jumper to the reset pin and see what happens I just have no idea if it needs to be a momentary, pulse, or continuous connection. What do you think of this plan?   

[KaFr]

If I understand correctly, have you already connected all the modules to the HV circuit, connected all the BMS and the LED of module number 5 is still solid green? Did you try to connect to EVSE to verify if charging starts despite error B40? Can you send me the latest data from the flash drive to check if any errors have disappeared?

I will try to ask MiBa about the correct procedure of resetting the module and then let you know.

BTW: Do you have any information from the previous owner under what circumstances the B40 error occurred? Is it the Brammo Empulse from this owner?

Correct I had all 7 modules connected to HV circuit and I turned on the ignition and the light stayed solid green while the others blinked as normal. But I did not try to charge the bike I will try that tonight.

Also I forgot to reinstall the usb into the bike so I dont have any new logs but I will do it for this next test

the previous owner said he rode the bike in the rain an shortly got the B9 moisture code then a few days later the B40 stopped the bike. Also I bought the bike from a guy in Alabama so its not the same as the one in the link.

It might also be a good idea to check the AIM Module connector as well.
There is an A6 error in the data - this module does not communicate.
Maybe the same problem with the ingress of water.

very good I will inspect that today also.
