Thks , I assume ur battery is fully charged ,
If so , check all the connectors in the back of the instrument panel
There’s a report of one of the connectors coming loose, make sure u disconnect the battery first
When ur ready to put the battery leads back on do a hard reset, u touch the neg and pos cable together for 30 x seconds , u may have to use a jump lead between them
Of course make sure no leads are touching the battery under any circumstances when u do this
Then reconnect the leads ensuring the battery terminals are clean and tight when u put them back on
Hope that helps and plse let us know how u get on
