I just replaced the traction controller and programed both the traction controller and the tiller handle card, everything worked as it should I then turn the key off unplugged the handset turned the key back on and tested all functions ( everything worked ) I reinstalled the cover turned the key back on and now nothing works, removed cover hooked the Zapi hand set back up and alarm incorrect start up pops up went through all test functions on the hand set and it all checked out. I am at a loss any help would be greatly appreciated.
