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?

Reset the low power B+ fuse on the doghouse.

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.

It's not on the back of the doghouse; it's on the left side.

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.
