Armyjoe127 Posted December 25, 2013 Share Posted December 25, 2013 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 Link to comment Share on other sites More sharing options...
Cheeky vimto Posted December 25, 2013 Share Posted December 25, 2013 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. Link to comment Share on other sites More sharing options...
Armyjoe127 Posted December 25, 2013 Author Share Posted December 25, 2013 Yes and I tried another battery ,, can I cnt understand why I loss voltage when I connect the motor up Link to comment Share on other sites More sharing options...

Supporters Rock-climby-Dave Posted December 25, 2013 Supporters Share Posted December 25, 2013 are the trigger contacts actually.... contacting? Link to comment Share on other sites More sharing options...
Armyjoe127 Posted December 25, 2013 Author Share Posted December 25, 2013 Sure if the motor isn't turning the gearbox cnt move , does the motor not turn the gearbox Link to comment Share on other sites More sharing options...
Armyjoe127 Posted December 25, 2013 Author Share Posted December 25, 2013 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 Link to comment Share on other sites More sharing options...
Supporters jcheeseright Posted December 25, 2013 Supporters Share Posted December 25, 2013 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. Link to comment Share on other sites More sharing options...
Armyjoe127 Posted December 25, 2013 Author Share Posted December 25, 2013 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 Link to comment Share on other sites More sharing options...
Spatch Posted December 25, 2013 Share Posted December 25, 2013 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 Link to comment Share on other sites More sharing options...
Supporters jcheeseright Posted December 25, 2013 Supporters Share Posted December 25, 2013 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 Posted December 25, 2013 Author Share Posted December 25, 2013 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 Link to comment Share on other sites More sharing options...
Supporters jcheeseright Posted December 25, 2013 Supporters Share Posted December 25, 2013 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. Link to comment Share on other sites More sharing options...
Armyjoe127 Posted December 25, 2013 Author Share Posted December 25, 2013 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 Link to comment Share on other sites More sharing options...

Armyjoe127 Posted December 25, 2013 Author Share Posted December 25, 2013 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 Link to comment Share on other sites More sharing options...
Supporters Liam Porter Posted December 26, 2013 Supporters Share Posted December 26, 2013 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. Link to comment Share on other sites More sharing options...
Supporters Ian_Gere Posted December 27, 2013 Supporters Share Posted December 27, 2013 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? Link to comment Share on other sites More sharing options...

Supporters Ian_Gere Posted December 27, 2013 Supporters Share Posted December 27, 2013 That's the one - I bought the gun second hand and it didn't have one. I never bothered to fit a fuse because it's awkward in the space available... Link to comment Share on other sites More sharing options...
Armyjoe127 Posted December 27, 2013 Author Share Posted December 27, 2013 U must remember the fuse is there to protect ur wiring and motor so u should fit one Link to comment Share on other sites More sharing options...
Supporters Ian_Gere Posted December 27, 2013 Supporters Share Posted December 27, 2013 I know - the problem is that the MOSFET I bought to replace the dead one is even bigger, so unless I shift the whole Deans connectors, fuse & fet into the handguard, there will be no room for a fuse. I need the bigger MOSFET though, because it has Active Breaking, which I need to prevent the gun from firing full auto when semi-auto is selected with an 11.1V LiPo. which I want for the trigger response. If I do that then I will have to keep long wires on my batteries, which themselves become a PITA on some other guns, my Inokatsu/TM AK-47S for eg, and being able to swap batteries around between my guns is pretty important to keeping the cost of my collection down...
