Problem with the electronics of my Centurion (I need urgent help)

[Helderluiss]

Hi guys

I have reached a point in the recovery of my Centurion where I cannot move forward. I connot figure out were the electronics that connect to the tower components fit and I do not have the instructions for this. also the cables were damaged when I bought it. I managed to figure out where the barrel elevation motor connects but I am completely lost to the rest. Can someone please help me? I´m attaching a diagram and photos of the mess I have ahead.
Thanks you very much.

The Blue/Brown pair go to the elevation motor as you have it.

The White/Yellow pair are a relic from the 12 gauge blank firer and aren't used in the Centurion.

The Green/Purple and Black/Red pairs go to the limit switches. I'll see if I can find a wiring loom with them attached but don't have anything to hand at present.

Thanks Adrian, I really appreciate your help.

Finally found one with the right colours .

At some point they started using a multicore with all black cabling

This is a from a Panzer III, so the lower switch is next to the mounting flange.

The upper switch has the red wire connected to the common terminal and the purple wire on the Normally Closed (NC) terminal.
The lower switch has the black wire on the common terminal and the green wire on the NC terminal.

Thanks very much Adrian. Great help

Well, I think I've reached a point of no return and I'm really going to need assistance. I've already redid all the wiring twice and I can't get past from here. The movement of the wheels, the movement of rotating the turret and the movement of gun elevation works perfectly

I cannot have any sound (I hear the initial three beeps but it doesn't go from there) and I don't have recoil or flash (but the servo recoils when I restart the modules to its initial position).

I think the problem probably is on the recoil and amplifier module.

I already did as instructed and pressed the small button on the sound module, but without any changes. Do anyone know who can repair these modules or in a more extreme situation, is there a way to replace all this electronics, is there an alternative on the market?

Thank you very much

One more information, when I press channel 6, which I dedicated to firing (that should initiate the entire shooting sequence with the flash, sound and recoil), I hear the click inside the module.

[Adrian Harris]

If you hear three clicks when you power up, then the sound board, the amplifier and the speakers are OK, so I would say it's a problem with the RC wiring. If the relay goes through the initialisation sequence, then the module is getting power, the relay wiring is OK and the relay itself is OK.

When you say "when I press channel 6, which I dedicated to firing", how have you done that ?

Only the motion modules have relays inside, so when you select and play a sound, so you shouldn't hear a click. You need to find which module is making that click, as that will probably show where the RC wiring is wrong.
