Hello!
I'm sorry to bother you,
I just registered, I'm Italian, I don't speak English, but I still try to write. Please excuse my many mistakes in your language. I also apologize if the topic has been discussed in the forum, but I haven't found it.
I try to restore an old Radicon Tank: opening the bodywork I saw three unsoldered cables.
Two cables (white and red) come from the turret, the yellow one from the battery compartment and provides 4.5 v power.
Anyone on the forum own a similar tank and could show me the wiring diagram, please? I've been trying for some time, but I'm zero in this subject.
I thank everyone in any case for your kind attention..
I'm sorry but I can't put picture until I post 10 messages...

You should make a few more posts and show photos. That will really help. And be sorry for nothing, my new friend, nobody else here is!!

Crius

Is your tank something like this?

Hello Crius!
Thanks for you help! Yes my tank is like that of the link.

E645

I had inserted a photo, but I have few posts.

E645

And now I find this incorrect way to reach the required minimum number ...

E645

What I do is incorrect, but it is the only way I have. I hope that the moderator can then delete these my posts. I'm very sorry.

Are the unsoldered wires in the Turret or the tank body?

Crius

Must admit this is a new one for me. It might be interesting to see what modern tech can do for this beastie.

@ Onondaga:
In the turret I found a desoldered cable and two points where it could be connected, I chose the most probable one, but I don't know if it is correct.
In the turret there is the on / off switch that does not work even if it has the cables connected. There is also the R / C receiver and a connection to a light bulb which should turn on when each radio pulse is received.

@ Crius:
It's a nice toy! I think it's the first remote control in the world. It uses the Coherer system and the radio control emits a piezoelectric signal (like a gas lighter!). But I think you already know this!
The problem with these Masudaya Modern Toys models is their fragility. Often the connections or the R / C system are damaged, after all they are more than 60 years old!

I know it's difficult to help me without photos, but I still have to reach the necessary posts. Also I can't post more than 5 replies in 24 hours.

E645

Waiting for the 10 posts I'm preparing the photos...

E645

All this is embarrassing ... I hope to prepare a clear text, but in addition to the linguistic difficulty it will also be difficult to explain the problem with the images. Tomorrow, at the end of 24 hours from my last reply, I should do it.

E645

See you later and thanks for your understanding and patience!

I have an old tin Stagecoach, motorized but not R/C, with the same battery compartment as this tank, from the '60s.

In italiano: ho una vecchia diligenza di latta motorizzata ma non radiocomandata, con lo stesso tipo di vano batterie di questo carro, sempre degli anni '60.

Interesting challenge.

Turret:
- I Antenna
- II Switch ON/OFF
- III Light bulb
- IV Radio receiver
I have connected the unsoldered cable where there is the red arrow, but it could connect to the other point indicated by the second arrow. Is it a spiral of copper wire (potentiometer?) which has a control lever located on the outside of the turret.
You can see it:


Five cables descend from the turret: RED and YELLOW from the radio receiver, WHITE from the light bulb, BLUE from the switch, GREEN (that was unsoldered) from the device with copper wire spiral.



Inside the bodywork the GREEN, the BLUE and the YELLOW cable -indicated with arrows- are welded over the actuator and the electric motor. The RED cable from the radio receiver and the WHITE cable from the bulb are unsoldered and I don't know where they should be connected.



The last one.
You can see: The yellow cable ( I ) comes from the batteries and supplies the motor and connects where indicated by the arrow. If otherwise it is connected in position ( II ) it acts on the servo -the metal disk with spikes- giving movement to the right or left tracks, depending on the position that the disc takes by turning. You can see also the RED and the WHITE cable without connection.



I hope the problem is only because of the unsoldered cables. I don't know if the radio receiver in the tank works. I have tested the remote control on another Radicon (Mercedes 230 SL) and it works, so I can exclude it as the cause of the defect.
I don't understand anything about electronics or wiring diagrams, for this reason I hope that despite my bad explanation you can give some help...

If you need more photos, just ask.
I thank you for your attention and for any suggestions.
