Brammo Enertia Servicing / Re: Enertia B7/B40 Error, bad battery
« Last post by ben nelson on November 11, 2017, 09:10:03 PM »
I pulled off the front/bottom cover to check the batteries in there. They all read 12.9v.

I completely removed the one battery which I already checked and saw had bad voltage.

Looks like I have one dead dead dead battery. Any idea where to get a replacement? The new version of the same battery has a different style of connection for the BMS.

I finally found an owners manual!

Looks like there's a few changes between the 2010 and 2012 model years. The bike I'm working on does NOT have the "Tank Button" for example.

Brammo Enertia Servicing / Enertia B7/B40 Error, bad battery
« Last post by ben nelson on November 11, 2017, 05:52:42 PM »
Hi everyone,

I have a friend with a Brammo Enertia. He was having problems with it and has no idea how to work on bikes (especially electric ones) and there's no longer any Brammo service available. So, he brought the bike over and dropped it off for me to fix!

He said that it had an error, but that it ran, although only at lower speed. When I got it, I could turn it on, but not get it into the run mode. (Of course, I don't even have an owners manual for the bike. I'm assuming that I just need the key on, the kill switch to on, kickstand up, and press and hold the start button. Let me know if I'm doing that wrong!)

When I turn it on, I can very briefly see a B7 error, and once the bike is booted up, it just lists a B40 error. An exclamation point in a triangle flashes on the display.

On social media, some Brammo owners suggested just plugging it in to charge and have the batteries balance themselves. Oddly, as I put it on charge overnight, the % charged went DOWN and the time remaining to charge went UP!

I also haven't had any luck finding an owners manual or repair manual for the Enertia. I'm not sure that a service manual ever existed. Any web links that I find to an owners manual all point to the same no-longer-there web reference.

I pulled the body panels off the bike to see what was under it. I was a little disappointed that I would have to strip off a bunch of other components to ever get AT the batteries. I removed the charger and a few other components off the top (tank area) of the bike and could finally get to those 3 batteries.

Two of them had little green blinky lights, but the third didn't. I checked with the volt meter and got 12.9V on two of the batteries and 0.3V on the third. Sounds like that's a dead battery!
I tried putting a little power into it with a "dumb" 12V charger, but it ammeter on the charger pegged at max right away. I also couldn't get power into it with my bench power supply. Sounds like the battery is dead and has a direct short.

I haven't yet pulled off everything from under the bike to get at those three batteries. I guess I'll have to just to check those three as well.

At this point, it sounds like it's at least one for sure dead battery. I don't know if there is a problem with the BMS as well, or if the issue was simply the battery.

Does anyone know how to clear codes on this bike?

I'll post some images. All input on this is welcome! Please help me fix this bike!

UPDATE:
Thanks for the response. I disassembled the rear set and kickstand. I stopped short of going any further because i needed to disassemble the clutch line in order to get to the front sprocket and I was not prepared to change the clutch fluid. Also without having the replacement parts needed I didn't want the bike sitting around in pieces waiting with a hope and a prayer to find a replacement part. I still couldn't tell exactly where the leak came from. So I cleaned up everything real well, put everything back together and topped off the oil. I took the bike around the block, ran it through some gears and parked it for 1 day with no oil leak. The next day I charged and put +48 miles on it. When I got back home I figured if there was a leaked at the front sprocket then I should have oil spray on the rear of the bike, there was none. Dumbfounded I parked the bike on the kickstand and waited. The next day still no oil leak. So after the second day I found a couple of drops of oil on the top of the kickstand. It seems that it only leaks slightly when the bike is leaning on the kickstand and takes a really long time to drip out. So I put it back on the stands and no leaks that I can see. I guess I'll just go by the local bike shop that was selling Victory and see if they have any suggestions or would be willing to work on the bike when I'm ready. The good news is that it's not spraying oil on the rear tire while I'm riding... To be continued...

Brammo Empulse / Re: Charger shows 0 Amps

The two small pins behavior is a little bit more complicated : https://en.m.wikipedia.org/wiki/SAE_J1772#Signaling

The 3.5V DC that you are measuring is actually a square wave between -12v and +12v.

Putting AC right on the bike plug will probably not do anything as there is a relay in the bike that cut the circuit through the charger.

I guess that it is the onboard charger itself that tell the EVSE to send AC. If the charger is not giving the order, it will most likely not close the charge relay in the bike and won't charge. :(
