Brammo Owners Forum

Korbin and others: do I understand the shop manual correctly (attached) that the lower battery module assembly for the Victory Empulse can be removed w/out removing the upper?

I made the CANbus and RS485 connectors for my Victory Empulse TT. Both work well. The RS485 plugs in directly to the top and bottom battery modules (separately). The CANbus is on the front right side of the bike - there are other posts about this.

RS485:
I followed the directions in this post including downloading the LabView 32-bit runtime software (thanks hackshack and others!): https://brammoforum.com/index.php?topic=4051.msg29217#msg29217

The connector for the Victory Empulse is different from the Brammo Empulse though. For the Victory you need this connector:
Molex # 0334721201, Digi-Key Part Number WM4735-ND: https://www.digikey.com/en/products/detail/molex/0334721201/1756779?utm_medium=email&utm_source=oce&utm_campaign=4251_OCE22RT&utm_content=productdetail_US&utm_cid=2187578&so=77360835&mkt_tok=MDI4LVNYSy01MDcAAAGGTCKL2RlzhabBLOEiIsLzs_lhEMI3Vxg-_Ia8CBKh9ylSvHPfkZI6ZCj7bdtuiAX1XZu8LkAKEVgUbcTgIBGR3h6NXUiSu06YTvjBnabL

You'll also need this contacts: https://www.digikey.com/en/products/detail/molex/0330122022/3184799?utm_medium=email&utm_source=oce&utm_campaign=4251_OCE22RT&utm_content=productdetail_US&utm_cid=2187578&so=77360835&mkt_tok=MDI4LVNYSy01MDcAAAGGTCKL2RmGfzIUNrZ1RmXiPo-E3oCje1jDLz1YnAJS-DOJM70IYAYV512zlcm8jG2-jKHFwdg_lMg7W4MoG1FvFEiS7PWg5pZZAArf_VAe

Watch a quick youtube on how to load the contacts for Molex - will save yourself some frustration! Might want to buy a crimping tool too, though probably could get by w/out it. A paperclip works well for adding/removing the contacts.

For wiring (numbers are on back of the connector):
Pin 2: A+ (black)
Pin 3: B- (white)
Pin 5: +12v (blue, goes to power supply, see below)
Pin 6: Ground (orange, goes to both the USB dongle GND screw terminal and the power supply GND)
Pin 10 and Pin 12 are connected together with a brown wire (essentially grounding the interlock pin)

Note: all other pins are empty (i.e. Pin 1, 7,...) - don't need anything in those pin slots.

I needed a 12V power supply (blue wire, Pin 5) and used the same ground from the power supply as the connector ground (orange wire, Pin 6). See attached image.

For the USB to RS485 dongle (3.3v): https://www.waveshare.com/usb-to-rs232-485-ttl.htm
I also have this one and it worked too (and cheaper!): https://www.waveshare.com/usb-to-rs485.htm

See attached image of software running. Unfortunately I have errors (my bike is dead with B40, see other posts).

I also downloaded this Serial Port Monitor, which allowed me to see what was being sent and received over the RS485 line.

I'll post the CANbus connector and dongle details later, though it's the same as the Brammo Empulse which can be found on other posts. With the CANbus + IXXAT dongle, I updated the firmware for the VCU, etc. see here: https://brammoforum.com/index.php?topic=4240.msg29186#msg29186

Hi All,

2016 Victory Empulse TT here. Has anyone had the System Fault A6: AIM Module Not Communicating? I read a couple other posts regarding A6 but I'm not even sure what the "Auxiliary Input Module" even is on the Empulse TT.

The bike won't run.

You can see my other recent threads that my bike has had a few faults recently and it's not working. Now the A6 comes on right away with key-on and then after some waiting the B40 is the final blow.

Thanks a lot

Hi All, Does anyone know where I could find the "Brammo Battery Communication cable" also know as the "Brammo Enertia powercycle service adaptor" (see pic)? Anyone interested in selling theirs? Thanks a lot

A guy near me is selling a 2016 Victory Empulse TT with ~1k miles on it for $6900. He has an extra fast charger with it.

Location: Eau Claire WI

Message me if you're interested and I'll connect you.

2016 Victory Empulse TT that I recently purchased with only a couple hundred miles. Worked super great for the first few rides but this morning:

[-] Won't turn on - nothing on the screen, no noises.
[-] However the horn and turn signals work.
[-] Was on charger for a couple days.

Tests I've done:
[-] Battery voltages are good (fully charged, 100% SOC).
[-] Fuses all good (in the fuse box)
[-] Ignition relay is not receiving 12v at key-on
[-] Looked at log files (USB under seat) and no faults, odd values, etc. up until when the bike suddenly shut off ~8 hours prior to me coming to check on it.

Any advice / thoughts will be greatly appreciated!

Hi All, The log files for a Victory Empulse TT 2016 are showing one fault in charging mode (#1 below) and one in driving mode (#2 below).   

Fault #1: After sitting on the charger for a couple days past 100% SOC, the log shows the fault "SYSTEM FAULT B62  : Battery Fault: One or more Heaters Failed". The fault seems to stem from "M2 Heater Current Bad Bits" which as logged this: .... ...!. Once this happened, this fault started.

The heaters seemed to be working just fine for a couple days while it was charging from 75-100% SOC and also worked fine after the motorcycle was turned on/off and driven post-charging.

Fault#2: "SERVICE MODE : Diagnostic Cable Connected" - this shows up continuously but only in the drive log but doesn't seem to impact the ability to drive.

I searched back through the older logs, Fault #2 may be caused by cold ambient temps?! Though this doesn't make a lot of sense.

Has anyone had anything like #1 and #2 above?

Thanks a lot for your help

Just took a 2014 Empulse R for a test ride to possibly purchase. It was a blast but unfortunately I noticed oil leaking on the underside (see pics and red circles highlighting the places that have drips on them).

The pic was taken from the left side of the bike down by the foot peg.

A few more higher-res images here: https://photos.app.goo.gl/Afxe8ggRCxJZ59WY8

I read through the forum for various oil leak reports though I'm still not totally sure my situation is the same as others.

Any thoughts / suggestions as to what this leak could be? I haven't bought the bike yet ($4.5k) and probably won't if there's uncertainty with these leaks.

Other details:
-1300 miles on the odometer
-The owner hasn't done any maintenance on it
-Was stored in his apartment fully charged

Thanks everyone - I really appreciate any advice / insight!
