My thermo cut out was behind the steering wheel on the dash. It is just a
pop out black button. I think the original owner through it out because of
this. I trashed picked it. charged the batteries, tried to run it and found
that the thermobreaker was tripped. Never seeing this on my other two
vehicles I pushed this button in and wahla it worked. Today it is probably
better designed than the two new units we bought.

Roy,

Don't forget to check out the thermal cut out that is located under the
"gas" pedal.
This prevents the youngster from using the car as a bulldozer.

This was on the units I was playing with anyway.  Give a look it can't hurt

BTW the car I had for the kids would pull 40 amps in a stall condition

Hi every body, I think I am in serious need of a crash course in Basic
Electric Vehicle 101.  My daughter has a little power wheels 4 wheeler
that is not working.  I thought it should be pretty simple to trouble
shoot, simply with a 12 volt battery charger and a MM.  The wire is as
follows.

There are two motors, both wired to turn the same direction when you
step on the accelerator. There is a accelerator pedal and a
forward/Reveres lever.  No on/off switch.  Using the charger I can get
both motors to run in both directions by simply jumping the charger to
the motor feed wirers and reversing them for the other direction.  That
is about all I can tell you.  I do not understand how the accelerator or
the directional lever is suppose to work and how to trouble shoot it.  I
can tell you this the directional lever has two 6 lead plugs going to
it, both motor have both of the leads in these 2 plugs.  The accelerator
has a single plug with 3 wires, two wires come from the 2 plugs on the
directional control and the other is a jump from one of the wires with a
resistor in the jump.

I have a second vehicle for the other daughter, that is working.  I
swapped out the directional lever, with no luck,  I "kind of" swapped
out the accelerator switch with no luck.  I say "Kind of the resistor is
wired in to the wiring harness of the vehicle, The wire on the resistor
on the bad car broke, so I swapped the switch and then jumped the wire
to the good resistor.
