Update to this problem - fixed with replacement MBB.

I've found two other cases of the flashing dash caused by dead MBB - one on this forum and another on Zero Owners Facebook group.

If you have a gen 2 Zero which has a flashing dash display and otherwise won't key on, won't charge and reverts back to this state after pulling and replacing the low.power fuse or MBB connections when keying on again, you likely need a new MBB.

It's a right bugger to get to the hex screws out by the way.

also interested in this answer. as an fyi i asked my local dealer this same question. they advised a  new MBB is £499.50 ex VAT. In regards to programming they werent sure. they advised they would first need to open a case as an issue and then send it back to zero to see what they say. this would start an hours worth of labour to open the case and then whatever cost zero decide to charge

So I found out some more info by digging through the unofficial manual.

The more recent bikes (?2016+) have a newer version of the MBB with more memory. This allows firmware updates by app, whereas the older bikes/MBB can only be flashed by the dealer.

The reasoning is that the newer MBB have sufficient flash memory to store the existing firmware AND the update such that in the case the update fails or is corrupted, you don't end up with a bricked MBB.

I was quoted £460-odd ex VAT for MBB including shipping it to Zero EU for programming. Potentially the newer one is more money? There's only really one dealer in UK. The place which sells them in Jersey where I am have the software but are unwilling to do any service as nobody is trained to use it. My bike is dead, I'm not shipping it to Norfolk, so my only option is to gamble on replacement MBB.

MBB is coded to bike with relevant firmware.

I have apparently dead MBB 2014 SR

I can get a good MBB from a 2020 S which is being parted out.

Anybody know if there are differences, or if I can get the 2020 MBB flashed to work with my bike?

Thanks. I am struggling to find this. Seat off, back of doghouse has two screw fuse holders, #1 labelled MBB, #2 DC-DC

Bike is 11.4 SR  UK spec

Reset the low power B+ fuse on the doghouse.

Zero Motorcycles Forum | 2013+ / 2014 SR - dead, dash flashing
« on: May 22, 2023, 05:03:38 PM »
Bike not used for about 2 months, stored outside under a cover.

The LCD dash is flashing at about 1 Hz apart from the clock which seems normal and keeping time.

The BMS righthand LED is flashing every few seconds (I think this is normal)

Nothing happens when keying on the bike, nothing happens when plugging in the AC cable.

I've seen a thread from a while back where the culprit was a dead MBB. I will try pulling the seat and checking fuses, unplug/replug MBB etc.

Any ideas otherwise?

The point is, I've logged full throttle pulls with the Sevcon's battery discharge current limit turned off. The log still shows the limit the BMS is trying to apply.



I had thought the battery limit was based on voltage sag - presumably it then calculates what amount of current draw is acceptable.

In cold conditions, my '14 SR sometimes hits some kind of battery limit under WOT conditions and the controller seems to cut power almost completely.

How easy is it to disable the Sevcon battery limit? I don't care about battery life now and would rather punish as many electrons from it as possible. I assume the Sevcon DVT software and a supervisor level password?

Is there such a thing in the UK as a rider's policy?
I insure my SR (full no claims) on a 600cc rider policy at £139.

What kind of sensor can detect lean angle?

Hasn't the Bosch stability system got lean angle sensor? Think there's a mention of cornering ABS, may also be used for traction control.
