trigger glitch

[eleven]

there seem to be a problem w/ my mp5j..most of the time, firing in single shot is locked..flicking to full auto then switch back to semi temporarily permits me firing singles..firing in full auto is no pain..but i want to ask what could be causing this trigger glitch..

[the_spork_of_death]

defective selector plate most likely, only way to tell is to take it apart

[eleven]

i have opened it but the selector plate seems to be fine..the spring is there..it can move freely the way it should..i have also checked the lever thats making contact with the selector plate and it seems to be OK..

anyway thanks for your reply..hope to hear from you again..

Locking in semi that's fixed by switching to auto usually happens when you release the trigger too soon after pulling it. Releasing the trigger too soon breaks the electrical connection before the motor has enough juice to fully cycle the gears and piston. Try holding down the trigger in semi to see if this is your problem. A weak battery, bad wiring, or strong spring can make the problem worse. Make sure your battery is strong enough for your spring and check for any kinks in the wiring.

And the other possibility is that the selector plate was badly adjusted when put back together.

hey ya...sorry looked did a search...sure soemone here has already answered it but could not find it....so no.."did you search remarks please...thank you"

my g36 was upgraded... it fires in full auto...but the trigger does not return to orginal position in semi...

could it be the trigger spring? or is it the side plate

sorry could not think of anything else

so i turn it over to you fine well experienced, educated airsofters

any contructive advice would be welcome

Hi !

Almost all the times when that happen, It's the trigger spring that is missing or badly installed !

Correct that and you will be all set !

The explaination for your problem is here.

Just wanted to say that it was a very well written guide/explanation on how that mechanisim works. Good job man !!!

I have the same probelm with my Kraken (don't say that the problem is because its a Kraken) and I would like to fix it. The problem is when I click your link I cannot view the web page. I get a message saying that I don't have the right privaleges. could some one pm me a copy and paste of it please?? (or something to that degree??)

[Dusti69]

i have that problem with all my guns gearboxes. from the kraken to an upgraded echo1 to a ca.
it is most likely as myoga said
usually happens if im firing it in semi too quickly

[theguy]

Don't mean to necro post, but i have the same problem, and the link is restricted for me, can someone explain the trigger assembly spring installation to me? or find me a copy of that page that i can see??

locking during semi-fire is caused by improper motor height. Adjust without the spring and piston. You could also remove the whole cylinder assembly so you could see the gears turn while adjusting motor height. By the way, use like 8.4V (or lower if you have) battery when you do this since your motor is not subjected to a load (spring uninstalled). You'll know the optimum height, you'll hear it.

[Kamepigo]

I belive hes referring to unlocks and if you still have the problem or ever do, try deleting your clientregistry.blob from the steam directory. It seems to fix most problems.

It looks like everyone's solution to this problem is the correct solution. Which ultimately means you should do a complete gearbox service. Shimming, aoe mod, trigger plate inspection or replacement, trigger contact points and re-grease of the mechanical contact points. Try a small amount (a skinning) of dielectric grease on the electrical contact points. It might help reduce carbon spots from arcing and also guarantee a better electrical contact. Also, as was said make fully committed trigger pulls this will reduce short cycling the gearbox.

The best gearbox you can build is built with the desire for excellence in its mechanical function.
