Jazzy Select Mobility Chair magical repair

[Freeple]

Any thoughts would be appreciated.

Jazzy Select was driven into a hole and then it just quit.
Controls light up but will not go.
Wheels locked up. Could not push. Yes, the release was thrown on both
wheels to allow easy pushing.

Circuit breaker on the front to the Jazzy was not popped but tried to
reset anyway, several times.

Jazzy Select was loaded on a furniture dolly and given a good shake on
the asphalt road while getting it home.

When home, the wheels turned freely and was easy to push.

What happened here ?

Engaged the wheels but the electronics on the arm rest throws a 9 blink
error code.
Means a bad connection to a motor.

Let it sit a few days while I researched and found nothing helpful.

Opened the Jazzy, disconnected the batteries and pulled the controller
box so as to get access to the tight connectors. One to the control
stick on the arm rest and two more, one for each motor.

I inspected the connectors, both sides and found absolutely nothing wrong.
Clean and almost like new.

Plugged it all back together and, the darn thing started working.
Seems to be normal operation.

Any idea what might have happened and what fixed it ?
Just re-engaging the connectors ? Maybe ?

Which model? There are four models that fit your truncated

Some chairs and scooters have tilt sensors to disconnect and lock the
motors if the chair is in danger of toppling. The newest models will
go up or down and incline as much as 15 degrees from vertical, and
about 10 degrees to the sides before killing the motor. The user
manual recommends 6 degrees (10.5%) maximum slope. The chairs with a
very low center of gravity can tilt more before shutting off. Some
also include anti-tip wheels and forks.

What I don't know is if your unspecified model Jazzy Select has this
feature and exactly how it works. I couldn't find anything definitive
in the manuals or on the web.

Did they power it off or disconnect the battery before transporting?

No power to the motors for some reason. Possible loose connection.

Ok, loose connection.

Congratulations. By unplugging the battery, you reset the alarm and
the electronics. My guess(tm) is the shock of driving it into a hole
set some kind of alarm condition that required either a manual reset
or a power disconnect to restore operation. That's why I asked if
someone unplugged the battery before transporting.

I would not suggest driving it into another hole to test if it's
fixed, but dipping it over (being careful to not dislodge the battery)
might be a worthwhile test.

As it happened during violent action, (driven into a hole) and you
got a bad connection error code I'd say the bump caused a bad connection
that was fixed when you disassembled and reassembled the unit.
It has happened to all technicians, take it apart, put it together and
it works. It's working, you can't trouble shoot it.
If you are a repair shop, the question is, do you charge high
expecting you will get it back and have to repair it free. Or charge a
low fee and then have the customer pissed that they have to pay twice
for the same repair. Damned if you do and damned if you don't!

** How true.

If you are a repair shop, the question is, do you charge high

** Give it a long soak test AND a long no use test too.

If all is still OK, bill for couple of hours.

Or charge a
low fee and then have the customer pissed that they have to pay twice
for the same repair.

** Or nothing - if you explain things to the customer and they get it.

The PROBLEM is that customers regularly fail to understand that ALL defects with their equipment BELONG to them !!!

Ownership does not change when they present the item for repair.

Same goes for anyone offering to help someone, like Doctors and Lawyers. Neither if these guarantee to fix your health or legal issues - all they need do is make a reasonable effort.

You pay for their time regardless of the outcome.

Gopher hole, giant sinkhole, or something else? Just curious and

If you go by the philsophy of "don't poke if it ain't broke" then leave
as-is. Or go back in, part and re-tension all the female spade connectors

There is a micro switch on some models that will go intermittent that
is located by the back axle. We had one that went dead and then
started working where this switch was the culprit. The rubber boot
doesn't adequately keep crud out of it.

Very common situation. My kid's car had the "air bag off" light on even
with an adult in the passenger seat. Replugged all connectors under the
seat, problem went away. Now, it shows NO light for no body in seat, and
ON for body in seat. That was yesterday's repair! I've got plenty more
of these replug and it just works fine stories.

With many of the computer controlled devices the first thing is to power
them off for about 30 seconds and back on. The second thing is to
unplug and replug anything with a connector.

Three is not enough current drawn in many of them to pass even a minor
amount of oxidation. That is one reason for most computer connections
to be gold plated. The old tin or tin/lead connectors on eairly
computers were very bad about that. Usually needed a pencil eraser to
be rubbed across the connectors.
