Sir surreyman . . . . . .
O.K. now . . . . . some more observations.
Addenda . . .
( Not now though, as you seem to show some out in left field controller . . . . did we not initially see that this unit has 12VDC power . . which must be three . . . . . ODD . . . . 4VDC cells in series)
Look at the spec plate on that unit as 42-48VDC and 35 amps and a whopping 1300 watts )
I thought what I have explained below was what you have, but just read and compare.
The very last photo that you posted, shows the rod that is mounted on top of the beam that reinforces battery mounting.
I merely see that mystical rod as pivoting up from the rear after being unclipped from the front, it then swings up to drop in a hole to support the hood / bonnet up.
Gadzooks . . . .nearby . . . .don't I even see hydraulic brakesused on that little puppy ?
Referencing to photo 2 of your posting, with your photo of the accelerator linkage being mostly blocked by the steering column rod and U- knuckle . . . I have marked up and filled in most of that area as shown below. *****
Here is what I see:
Phantomed in as silver, at the top center is the accellerator linkage, AS ACCELLERATOR LINKAGES ARE, it is spring loaded such as to have tension in the opposite direction of the top arrow.
Little GI Joe hops in and presses on the accelerator pedal which causes the opposite side of the linkages replication, extending down from the silver gland nut, to move in the opposite direction of travel .
Such direction as is marked with nearby yellow arrow.
The contact at RED STAR lets the A portion . . . .CARBON RESISTIVE CONTACT BLOCK . . . proportionally slide down inside separate telescopic part B.
There is encircling pressure electrical contact pressure engaging into the rectangular carbon block guesstimated within the ORANGE rectangle profile.
Initially the two A and B ends are electrically separated by a spacing, for no power flow, but after a slight movement towards each other, electrical contact is made at the highest resistive value of that carbon block to the B pressure contactor.
As the accellerator pedal is progressively pressed down, the telecopic action makes the resistance blocks length shorter . This produces lower resistance and higher motor speed.
The extreme limit will be when the GREEN X and X prime ( they are replicated on the other side towards the steering rod) bottom out and meet each other. Max speed is at that very low resistance setting.
INTERJECTION . . .
A Delmer Pee Dumbnuttzz type of simple solution would be to clean /scarrify/degrease the polycarbonate at point X and install a premeasured block of hardwood there to limit the X prime travel direction towards it and adhere with silicone rubber adhesive and do CURE WELL.
Of course one twin spacer block, is also being needed on either side.
Casper Pee Cloddd's more involved solution would be the use of longer screws at the RED star end of B and two washers that go against the polycarbonate block and cut out a rectangular metal bracket of 1.5--3 mm thickness that replicates that end quadrants width and has the central slot cut in it for the RED star dimension and then extends outwardly in the YELLOW arrow direction, in order to get enough length to fold over to make a right angle bend downwards and stop the end travel of the A portions protruding end.
Forming slotted holes in the bracket, at the added longer 2 screws + 2 washers + 2 star lock washers, let you then adjust the travel limiting bracket add on, to precisely 24.i44444786 KPH.
OBSERVATION . . .
Near the A block observe the use of doubled wiring for current capability and the trailing off routing direction with the RED dots.
The companion connection of the two ORANGE dots wires must go into the single B contactor assemblies black spiral accordion tubing being shown in its sole photo.
ASIDE . . .
In posting #29.
It doesn't seem to have any way of connecting to that 3-way plug/socket alongside.
Unless its just being used for size comparison, I believe that the 3 pin connector is being a red herring,and not being of any speed control association..
veet nam . . .VEET NAM ? . . . . . you should have come back with your fluent reply of
