Gun doing nothing

[Armyjoe127]

Hi my asg beta spetzan ak47 will not do anything , it's only had 600 pellets fired . It just stopped all of a sudden , I have checked wiring and all is ok, so I disconnected the motor and checked at terminals voltage .voltage is present when I pull trigger .when I reconnect motor I seem to loss voltage , even when trigger pulled nothing , what am I missing

 

[Cheeky vimto]

Is the battery charged?

Similar thin happened to me before and I ended up having to buy a new battery as my old one weren't holding charge.

 

[Armyjoe127]

Yes and I tried another battery ,, can I cnt understand why I loss voltage when I connect the motor up

 

[AK47frizzle]

Your gearbox is fucked

 

[Rock-climby-Dave]

are the trigger contacts actually.... contacting?

 

[Armyjoe127]

Sure if the motor isn't turning the gearbox cnt move , does the motor not turn the gearbox

 

[Armyjoe127]

When I put multimeter across the 2 wires to the motor I'm getting voltage with motor disconnected and trigger pulled , I'm sure this is as it should be , but when I reconnect motor and pull trigger I cnt get voltage , strange

 

[jcheeseright]

Sounds to me like your motor has had it, if you're getting a drop in voltage when you hook up the motor try running it with a different one.

 

[Armyjoe127]

I'm getting no voltage but if I take out the motor and connect it straight to bAttery it runs , I'm sure it cnt be to complicated but I dnt want to strip gun down As it was got to my son for Xmas so maybe be better to send it bck , I'm sore the electric on these guns just runs throught trigger system to motor

With the motor in the rifle correctly and all wired up and all back together like normal, when you pull the trigger do you hear anything or feel anything in the pistol grip?

Is there a fuse anywhere along the wiring, most rifles have them, sounds like your gearbox has locked on the back of the stroke and the motor isn't able to pull the last fraction to release it, if you can see the anti reverse latch at the bottom of the gearbox with the pistol grip off then it needs releasing

 

[jcheeseright]

The wiring on an AEG is really simple as you said, just a case of the live (I think) wire running through the trigger block which is a simple switch. If you're getting voltage across the terminals with no motor in then the wiring would appear to be fine. Only component that could be dodgy in that case is the motor.

If it's still in warranty my recommendation is to send it back, no point fixing it yourself when someone else is legally obliged to do it for you for nothing!

 

[Armyjoe127]

Thanks spatch what I cnt seem to understand is when I have the motor sitting out of the gun why will I not run , is there another component in the trigger system stopping it , when I just power up the motor straight from the battery it runs, fuse seem ok but I'll check it again

 

[jcheeseright]

Oh, in that case it sounds more like your trigger isn't working correctly. Like I said, send the bugger back, it's a simple fix but not one you should have to do.

Unbelievable I got it sorted guys , it was down to one a cheap shit fuse , I checked this fuse with multimeter and it was belling out , so as you would think fuse 100% . Still gun not working so checked all wiring and motor all ok , soi took fuse out of circuit and gun firing , what?. Replaced with a new fuse and gun working but blew fuse after about 20 shots, found small hole in wire insulation so repaired and replaced fuse and all seems ok ,im a electrican and have never experienced anything like this with Fuse in my life, unbelievable and still confused lol

so basically that gun has weird irregular current surges? hmmm that is weird...

 

[Armyjoe127]

I dnt know frizzle but with everything on place I was gett 9volts at motor but it wouldn't work it had my head fried so I took fuse out of the equation and it fired , I know now the fuse had broken at the end and was still belling out against fuse end cap, just checked it on ohms reading lol

 

[Liam Porter]

My gun blew its fuse after not long, replaced with another which blew after 20 shots or so. Checked the circuit and everything seemed fine, another fuse, exactly the same. Re-checked the wires and everything, all fine, then blew another fuse. Completely removed the fuse now, been running for over a year with no problems at all, and it's had a lot of use.

Never had any airsoft gun like fuses, to be honest, I've not really seen the point in them.

 

[Ian_Gere]

I could have done with a fuse in my AKS-74U t'other day, when I somehow shorted the circuit and almost melted the wiring, in the process cooking my Pico SSR MOSFET to death. I spose it's important to find the right fuse. Can you get 45A ones that small?

 

[Armyjoe127]

Yip I suppose u could , did u not have Fuse onT all

 

[Armyjoe127]

Did u have no fuse in At all
