Thanks to those who offered advice about getting my eZee-bike back on the road.
The problem was solved when I noticed that the 36 volt battery spring-clips were not making contact at all with the battery. A couple spacers under the connector and the bike came alive.
(I remembered reading a posting some months before I got my E-bike, that covered this condition. I was never able to re-locate that posting and would really appreciate any help to find that forum which did have lots of additional info on eZee-bike wiring concerns).
So, I'm finally able to take it out for a test-drive. And it all worked beautifully!
Of course I still have questions about the "cruse-control" control, about why the tail-light comes on when the power is activated, about the "P-E" function, about reinforcing the kick-stand, about difficulty shifting through the 7 speeds, about why the "light" button won't depress and seems frozen, about etc., etc., etc.
But we'll get all that sorted out in good time.
So thanks again for your suggestions on trouble-shooting the main battery problem.
