asiatam recoil

[thunderbolt]

Having problems getting the asiatam recoil to work with a Clark board.
Have connected it up as per instructions on clarks site, can get the drive motors running, turret traverse and flash but no recoil or elevation
Elevation is on 6&5 on the board, but nothing, same with recoil motor + feed picked up off turret wiring and - to 4 on Clark, nothing, motors are ok on the recoil unit, checked with battery, wondering if I have a faulty Clark board or if it's me.

thunderbolt, maybe I am reading it backwards, but elevation motor should be connected to 3/4 on the 8 PIN Hull patch board, and the recoil motor should be connected to 5/6 on the same board. you didn't mentioned the microswitch for the trigger and that needs to be hook-up as well. I also assumed that you have a Neg- coming from the battery/main switch for the thicker cable as well out out of the Asiatam unit.

I hooked up 2 of them to the clark but I seem to recall there were some fiddling around. You also jump the blue and the white wire together from the two motors, right ? Or connected them to the switch in the turret ?

Just looking at the unit I received yesterday, there is a 3 PIN plug which correspond to the three point patch board on the hull. The 2 PIN plug goes to the trigger, and the thicker wire with neg need to be wired to the power directly for a Neg-.

Maybe you can send a pic ?

Hi Michale
Have jumped the blue/white wires, but looking at Clarks site it shows 5&6 as elevation, 7&8 turret traverse and a live direct to the recoil motor the Neg as 3.I can get the recoil to work by bridging out the recoil switch but can for the life of me work out how the motor picks the neg up through the recoil switch.
If you have a photo or wiring diagram that's worked on yours that would be great
Thanks Colin

This might help a little....

Okay, just open up the hull but didn't open up the turret. Hopefully you have the same colour wires.

The two wires coming out of the microswitch for the recoil (There is two microswitch I am talking about the one behind the recoil, not the one inside the recoil gears) should be connected to CN3 PIN 4/5 on the clark board

The three wires coming out of the two motors (in my case it was Yellow/Red/Green, but I just noticed on the latest recoil I got it already has a three pin plug at the end and not leads and the colour are RED/BLACK only), The Yellow goes to PIN 4 on CN9, Red Goes to PIN 5 on CN9 and Green goes to PIN 6 on CN9. If you don't have the same colour wires you should be able to sort this out between the motors. There should only be three wires coming out of the two motors because you jumped the blue/white wires together so just map the different motors to the different PINs.

The single thicker wire (It could be red or black), or in mine is was one of the ends coming from the microswitch inside the recoil gears, is the one that should be tap into the Neg- on the main power switch.

Finally, clark defaults to Tamiya recoil and just for correctness you should program it to HL Recoil (Power button on the remote and it should flash 3 times for HL Recoil). I don't remember this making a difference on mine but you should do it anyway since we are doing diagnostic.

Thanks Michale
I think the boards set to Tamiya as you said, I'll reprogramme and wire it as HL does the strobe just plug into the cn3 as shown, it's just that it did work, now doesn't just get very hot on the black box, don't know if I've blown it trying to get it to work, was ok to start with.
Looking at the wiring the HL and Tamiya recoil are the same numbers,I think I can now see where I'm going wrong

Don't forget that on the Clark board, the elevation motor and the recoil motor don't share the same power supply as they did on the Heng Long board...
You have to cut the power supply wire that goes from the elevation motor ( + ) terminal to the recoil switch; and then use an extra wire to connect the recoil switch terminal to the power given by pin 3 ( which also supply the leds)...

To make things clearer: On the Heng Long board, the elevation motor and the recoil motor share the same power supply, ( the small red wire)

On the Clark board: The elevation motor is using the ( small red wire ) by itself; since it now turns in 2 directions...
The recoil motor needs an extra wire to bring the power from pin 3

I couldn't get my Clark to work the Asiatam recoil unit and it was wired up correct. Tried reprogramming the settings but no joy.

I put it down as the Clark not providing enough power or power it long enough so the motor has time to work. But just by chance I wired up a hobby engine Abrams tank with a Clark board this week and the recoil works on that! But problem is it fires makes sound then the motor recoils so the timing setup seems totally out.

Wow Ian, clark board with Hobby Engine M1........ You got to post some videos.

I did manage this. Get the clark board working with the asiatam recoil and that's where I got the wiring details from. Like I said I do remember fussing with it quite a bit so maybe I will open up the turret and map out the exact wiring and post it here.

Well been busy so not been posting to much lately, but basically bought 3 faulty HE Abrams off ebay as faulty. Couldn't get any running so ripped electronics out of one borrowed TK20 (T55 sound) from another tank and got it up and running.

Went to our monthly tank meet last weekend so here's a video from a mini cam I put on the turret.



Clark isn't releasing the Abrams sound board until September so will have to wait until then for the correct turbine sound.

PS Thunderbolt sorry for going off topic. Plus I bought one of the IBU2 boards I mentioned hopefully will arrive next week.
