555 Error on Dash after Battery Replacement
« on: July 24, 2020, 06:35:54 PM »

Seeking HELP from the wisdom of the crowd.  I purchased a ZF13.0 monolith battery for my SR after Zero refused to replace under it or the bikes 2ND defective charger under warranty.  Installation was simple enough, much easier to accomplish with two sets of hands.  Finished, yet not so fast.  Turn the SR on and the dash flashes several error codes relating to the controller 25 (contactor open warning), 48 (controller startup failed) and 49 (contactor open disable) and the same time 555 is appearing on the bottom line of the dash.  Wouldn't 666 be more appropriate?  While this is happening the contactor is clicking open and then closed, opened and closed continually.  Eventually gave up and decided to put the original battery back, but then it was doing the same.   Sure this is just some error that can be reset.  There's no throttle, the lights are on and if I turn the rear wheel theres a sound after several rotations.  Nothing else.  New dealer refuses to offer any guidance, but they're a horror story for many it seems.   Any assistance most appreciated.

Try to reset the BMS on the battery and the MBB on the bike. You can find the instructions in the " Unofficial Zero manual "
