What contacts should be closed on the board of the radio-controlled car in order for the forward-backward / left-right command to work without a remote control?

Question

Electronics

Hello!
Actually, subject :) I
am attaching a photo of the microcircuit.
It is necessary to check the board for operability, which contacts need to be bridged so that the machine starts spinning the wheels without using the control panel.
Thank you.
P.S. I don’t rummage in radio electronics, so I’m waiting for the simplest possible answer, like “close this one and this one and it should work” :))

Answer 1

Do you want to do something? In this board, the main function is to receive, understand and execute commands from the remote control. Without him, it makes no sense. Therefore, there is no need to check its performance.
To use the machine without a remote control, you can simply throw out this board and control the motors with any mechanical switches. There you probably have two motors - one turns the wheels, the second turns the "steering wheel" left and right? If so, then they just need to be energized, and the direction of rotation is changed by changing the polarity of the power supply.

Answer 2

Well, to check the motors, you need to supply power to them,
let's connect
red-yellow and black-white
red-blue and black-white,
but the motors are the last thing that burns in these machines

Answer 3

The motors are both working, both checked with 4.8v power supply as it should, directly. But for some reason, if I give the power supply voltage to the board, through the standard connection of the power source, the wheels barely twitch when you press the remote control, they barely try to turn it .. If I give the board a load higher than the declared 4.8v the machine consumes, the wheels start spin. At 6v it was barely barely, at 9v it was also weak, it spun and stopped, gave a load of 12v for literally a couple of seconds, smoke came from somewhere, but the wheels spun briskly. The condo alone stands at 10v and 100uF, I sin on it, I checked it with a multimeter without soldering it, although it rings, it seems to work ... Or maybe it doesn’t work))))
Maybe the frequency with the remote control runs up, then you need to turn the antenna on the board. Yes, there’s no way I can close the wiring on the board in order to check whether the command is going through the board or not?
