Question about Jet 3 Ultra Power Chair
A few things to consider: A blown charger fuse can cause the charger inhibit to activate. Determine if all controller connections are plugged into the power base properly. If the 3-pin charger inhibit connector is not plugged in properly, then the charger inhibit feature will activate.

SOURCE: Jet 3 Ultra won't charge
Indeed, you need to find a repair shop. Try a google search for power chair repair, or ask your local hospital or if you can find one a power chair store. Most likely, you have a mechanical failure of the wiring, the battery themselves, or corrosion on the battery posts. Since the chair lights up when the charger is in, it is unlikely that the charger is broken. You may have a failure of the controller board, but that is also unlikely. And batteries do not usually suddenly fail completely; they typically fail slowly, losing the ability to completely charge.
I assume that you did not see a great deal of fluid leaking out of the battery container; you might look in the container and check to see if a battery is cracked or missing fluid.

Sounds like the batteries are completely dead, you'll probably need to replace them, sometimes you can only use batteries until they die, and that goes for Wheelchair Batteries too. If they won't charge or keep a charge then they are dead.

If you have access to a voltmeter,put it on your battery then plug in the charger; if the voltage rises that will tell you that your charger is working.

Hi. A voltage of 34 volts is way to high. Most chargers are limited to about 28.5 volts. You will quickly dry out your batteries at 34 volts. I would say your charger is very faulty.
You have probably already destroyed your batteries at that charge rate.
Are the batteries new or a couple of years old.
I serviced a machine last year, that, according to the owner, had been through 6 sets of batteries in 4 years. His charger had the same problem as yours.
Good luck. Neil.

I am assuming you have a Jet 7 with a VSI controller (manufactured by Penny and Giles) with a steady flash of all the speed and profile LEDs (lights). This is a no drive away feature of the VSI if the charger is plugged in. The older Penny and Giles controllers indicate the same flash code.
If you have an on- board charger check to see if it is plugged into the wall. If it is, unplug it and see if the chair runs. Sometimes, you have to remove the back cover and unplug the charger haress at the output of the charger inside the electronics housing (much more difficult). A failed on-board charger can inhibit the VSI controller (no drive away) even if it unplugged from the wall outlet. There is also a charger inhibit harness with a fuse that might have failed. A qualified technician can jumper this harness to bypass and test.
If you have an off-board charger unplug it from the wall or unplug it from the charging port in the front of the VSI. If the chair runs in either case you have a bad charger.
You may also have a bad VSI controller which can be rebuilt or replaced. Start with the basic charger unplug tests and then work your way to the VSI controller. Hope this helps.
