Wiring connections - non-bb Tiger 1 recoil mech

[OldTanker]

I've managed most of the connections of my Taigon Tiger 1 to my replacement Tongde controller board, but I'm uncertain with this unit.

The secondhand Tiger kit came with the parts for either BB firing or IR battle, and I swapped the BB unit for the IR recoil/firing mechanism. I guess it plays no part in infra red battle, and just elevates and fires the gun ?

It has two sets of wires, a red/black pair that are connected to a spring contact set that I assume flashes the LED in the barrel, and a twisted set of three red/green/black that I assume elevate and fire the gun.

I connected the red/black pair to the Tongde cn6 'trigger' port, but I'm uncertain where the gun LED should go, and also the red/green/black, as instead of the 3 pin plug the Tongde only has 2 pin ports.

I'm wondering whether the black is a common neg, and the green and red should go to which two 2 pin ports ?

Good morning,
For CN 6 (Trigger) I would say that it is OK. On the other hand, your “Asiatam” recoil system does not seem compatible with your plate? in fact, the 3 wires are good for powering the motors, a common one, one for the reverse, one for the elevation. You also have the Blue (black sheath) which must be connected to at least the Accus. If you look at the diagram (photo) it is indicated that these 2 functions are carried out by servos? Ch1 and Ch 2 connectors. while the motors must be powered by 5 volts

I've tried carefully connecting a 2s battery to each of wires on the gun unit, and when I put pos on the red and neg on the black the gun does cycle through elevation, but when I try other combinations (like pos on the green) nothing happens.
I then tried connecting the red and black to CN3 and then CH1, but no response from the elevation movement then when using the controller left stick.

Well, maybe I'm mistaken? Indeed it seems (after examining the photo diagram) I would say that it might be possible to connect the elevation of the barrel to CN 4? (cannon lifting) but by modifying the wiring, no more in common? but 2 wires per motor, on the other hand the +/- direction to be seen in the tests without junction with canon'....the other I would say CN 10? but without conviction, which amounts to doing according to the photo below

PS: Do not take into account the 2 resistors of 2.2 Ohms, present only to possibly slow down the speed of the motors

Thanks for the very prompt replies Jofaur, I'll look carefuly through what you've said here but I'll have to go offline for a while.
(someone downstairs mumbling something about 'Christmas Eve' or something.....

[Jofaur86]

It's funny but I also hear voices of the same kind? I wonder, where it comes from, no worries, Merry Christmas.

[OldTanker]

I've escaped again....

I think the main problem I'm facing is that I don't fully understand the correlation between the main gun optional electronic sub assemblies.

I'll have to do a bit of Youtubing.....

Attention, Ch1/2 are for servos, and therefore 3 +/- pins and signal wire, danger for the board if a wire reversal?? in principle there is red, pos.black, neg. and yellow, brown, white control signal. And are well indicated, Retreat and elevation.
looking at the photos? on the first, there are actually 3 wires, yellow terminal = common to 2 motors, blue terminal = elevation, brown terminal = recoil. This is the original Asiatam wiring, which is found on the eight-pin connecting plug between the HL board and upper chassis. In the photo below? blue/yellow terminals = elevation and brown/green = recoil the micro contact under the recoil gear is the switch which controls the flash, when shooting/recoil, marked “Safety Switch” in the photo.
on the other hand, I know that on certain decks, it is not necessary? is this the case here?? maybe a forum member who knows this platinum type can tell you?

[Jofaur86]

for the thread colors, I found this on a former French Forum for the group of 3 threads:
Black = motor elevation
Green = motor reversing
Red = common recoil / elevation, because there were a number of different colors at Asiatam, on the other hand it would be great to have a photo on the motor side, because there may be a shunt carried out, between 2 wires?

[OldTanker]

That was exactly right Jofaur, thank you.
When I connect a 2s battery to red and green, the recoil works, and when I connect it to red and black green the barrel cycles through its elevation.
The wiring of the tank was quite mixed up when I bought it, (secondhand), and now that I've replaced the original Taigen MCU with the Tongde, there were a lot of redundant intermediate connector boards and ribbon cables, so I had to trace the function of each component part and fit a new 2 pin plug to plug it into the Tongde, which had completely different sockets to the original Taigen unit.
I now have all of the electrical functions working via temporary connections, so I'll post up some photos on my build thread when I've tidied them up into a single flexible connecting loom.
