Ok. You shall have next time he works on it.

There're two points to it; firstly it's no good taking it all apart,
and then asking me how to put it back together, and secondly
I'm interested in what you find and may even spot something you
missed. Photograph everything.

Ah, connectors. The speed controller will only be easily removeable
if the wires to it go through plugs and sockets. Plugs and sockets
can get water in them, too.

Come to thinkof it, the crosser began giving me problems in the summer
last year, in lovely sunny weather.

That's not fair, changing your story!

It was on full speed and tried getting it around a toll bar and it tipped on it's
side and was never quite right after that.Made a funny noise, I think from
the axel and lost speed something awful.

So it sounds like you damged something. You might have more than one
fault, you know.

I've had it in to reperation.
"For repair".

It came back as it it now. Low speed only on flat surface.

And you accepted it?

I wondered, could it be the breaks.

Yes, it could be the brakes. It could be lots of things.
You've got to have a _reason_ to suspect a particular fault.

The fault-finding process is a sytem of inquiry, observation,
and elimination. It's not guesswork. I am not psychic.

Problem: cart goes slowly.

Possible causes:
Power (electicity) supply
Power (electricity) controller
Motor(s)
Transmission
Brakes.
External causes (You're dragging a tree/moose/cyclist behind
you/ you have a traffic cone/tree stuck under the wheel arch.)

Yet suddenly, up hill, it's on full speed again.

So it's not (likely to be) the brakes. Brakes are either on or off.
(Note: some braking is done by the motor speed controller.)
(Since you've crashed it, test the brakes.)

It's also not (likely to be) the transmission. Axles, gears, bearings
and such run freely, or they do not. (Since you've crashed it, it
wouldn't hurt to look for damage.)

It's also not (likely to be) the power supply. Batteries are charged
or they are not. (The battery charger indications helped to eliminate
the batteries.)

It's also not (likely to be) a motor. Motors tend to run well or stop.
(Do the motors have brushes? How much use have they had?)

The power controller (motor speed controller) can produce all sorts
of strange symptoms as it has a lot of ways of going faulty.

Ok. I'll ask him read your posts. He'll be home late tomorrow night and
then he has a gig on Sunday so it could take a while Sleeps.
Thank you.

You were seeing me in action there: that's what I used to do
for a living. :)

No way. Just the man we need.

Please understand you have to be clear and accurate in your
descriptions.

Edith.
