Back in summer i bought one of these, mainly to have a V display of the Volts in my battery.. been off the bike for a few weeks after a total hip replacement and earlier this week i ventured out to my workshop to charge and refit my battery, switch on and check everything was kosher.. no display, well a vague display , no info or colours, checked output at battery was good 54v, checked loom connections all good, and tried again, in despair i wiggled my digit on the power button and hey it came alive, switched off and tried again , still dead as Nelson, so it must be the switch albeit how does it switch off so normally.. emailed Luna with invoice details who came back with Sorry outside the 90days warranty, we'll give you 30% of another.. i have the old basic Bafang display and has anyone cut and joined the older switch to another similar display, or have any ideas what could be wrong, its never seen any amount of rain, dry stored, cleaned regularly and hasn't had any sharp shocks or damage.. help?? will
