Below is a website that should prove useful to you; I also included a phone number for which you can call and possibly get a more direct answer for this, as they will be able to tell you what the "7 blinks" indicate, as well as why the brakes are locked up.

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.

Good luck!

A 10 bar flash indicates An excessive voltage has been applied to the VSI. This is usually caused by a poor battery connection. Check the battery connections. Make sure it is not a 9 bar flash, that is an easy fix by resetting the manual brake levers. Check this site for more info:

Normally the power chairs will not operate when connected to the charger. If you mean the controller comes on when connected to the charger but it wont come on when the charger is disconnected, I would test the batteries first, then the connections and fuses. Did a technician inspect your power chair to determine a controller was needed, or was that just a guess by the representative over the phone? If your insurance will not cover the repairs, I would recommend spending $50 for a technician from Hoveround to come out and inspect the chair to determine what is needed to fix it so you know for SURE. It may be something simple and inexpensive.
Good luck!

you need to have your battery load tested if there is a short in the battery it could trick the charger into thinking that the charge if full, i normally use a 100 amp tester on 33 amp batteries. look in the phone book for a batteries plus in your area they may be able to help and may have the batteries you need, be ready batteries are around $100.00 depending on the size and some units have 2

Five flashing lights indicate Right Motor Wiring Trip- The right motor has a short circuit to a battery. Check all the connections and leads between the right motor and the battery.

5 bars indicate a short circuit from the right motor to the battery. Check all the connections and leads between the right motor and the battery.

Under the seat on both sides there are two grey battery covers. Squeeze the pinch clip buckle to remove the black webbing strap and lift the cover off carefully. You may have to turn the seat to the side to get better access.

Problem solved.
