This one is even better.
Did your trip odometer quit working??
Here is the trip reset arm
It hits the little white lever
This is unpressed. You can see the grey arms that run around the numbers.
and pressed. You can see the grey wheels lift off the dials.
When you press the trip reset it pushes the black arms here. Kinda behind the dials and under it.
and it hits the black piece around the axis of the dials. You can see a white plastic stopper on the axis then the black oval coming out.... that's what the arms push back to get it at zero.
This is the motor that turns all the dials.
