An 8 Bar Flash on the controller of a Teknique FWB indicates:
Possible Control System Trip
A control system trip is indicated. Make sure that all connections are secure. This means that one of the wires attached to the junction box, or the umbillical, may have come disconnected.
Is your power chair equipped with an optional power seat lift? If not, raising or lowering the seat will not restore function to the power chair. Have you tried doing a brake reset just to see if that will help? The manual brake levers are under the bottom front of the chair base; turn off the controller, pull the levers down then push them back up until the pop into place. This reset will clear many issues.
If you are able to check the wiring for the junction box and wish to remove the seat, you can do so, but the Teknique series is terribly difficult for the average end-user to work on and is recommended that a Hoveround Technician do it. Hoveround will not even ship batteries for self-installation to owners of any of the Teknique power chairs because they are such a pain to work on. The seat must be fully removed to gain access to the batteries under the motor cover and most power chair owners do not posses the kind of strength and dexterity needed to do it.
The seat post can be removed by removing a bolt underneath the seat, you will also need to unclip the black umbilical cord leading from the controller to the motor cover so that you do not yank it out when you remove the seat. The motor/battery cover can then be unbolted to allow you access to the batteries and junction box. I cannot give you details on how to do this, because as a Hoveround Tech Support Rep, we are instructed to dispatch a technician for the customer's safety and I have never done it myself or even seen it done.
If your Hoveround was purchased via your Insurance, they will most likely pay for the repair, but it may take time to schedule the appointment if the Insurance requires documentation or verification before allow the repair to take place. If you are in need of additional assistance, please contact Hoveround Tech Support at 800-964-6837 on Wednesdays or Thursdays when the call volume is lower. It's worth a shot.
