*click* sound when tryin' to shoot.
 

Well hello there ASC community.
So today, I went out with my AK outside, test firing it after I installed my SCS nub.

But then, it shot a few time, before stopping and the motor just doing some kind of *click* sound when I press the trigger.
Also the battery gets really hot when I hold the trigger like 5 sec, aswell as the fuse.

Battery - Intellect 9.6v 1400mAh
Spring - Guarder SP120
Motor - TM EG1000.

What could be the cause of my problem? I haven't opened the gearbox yet.

Charge the battery. My XM177 does that when the battery cant turn over the motor and I get the same symptoms you do.

Alright I'll try that, I know that the spring recommended battery was at least 9.6v 1700 mAh Large. So it may be the problem, I'll wait for my batteries to charge up and then I'll try, I'll keep you informed.

Edit: Tryed with a full charge battery, and it didn't change anything, still the clicking sound. The battery gets really hot and the fuse too.
Should I open my gearbox?

Sounds like your box seized. Could be something wedged between your gears, also if your motor is wired backwards, it could be fighting against the anti reversal. Could be any number of issues. One way or another, your gonna have to open your box to find out.

Get another battery to test with, preferably a large.

I'm opening the gearbox, something went wrong apparently, the gear doesn't move. I'll look onto it.

Edit: Nothing seem broken... It all look pretty good so hmm, what could be the problem? The motor still rock on.

Like we were saying, the battery.

The gear were stuck.... Not even movable with my fingers. + The battery used to be able to push it.

I know I sometimes have that problem if I do not have my selector arm/gears just in the right sweet spot for my AK.

I basically have to move it just ~2MM past semi to get semi, otherwise just clicks.

Full auto works fine for me though.

Metal gears are stronger than your fingers.
Try a LARGE CELL battery.

Hey guys, good new, I reassembled it, regreased, and it work good now!

HAHAHAA this is so true.

I understand your frustration here, gets me sometimes too when I'm 100% sure what the problem is.

There's a significantly easier way to solve it, but the OP just utterly ignores your suggestion and instead the other 10 guys suggesting otherwise proves more convincing to the OP.

Btw, Styrak is correct on the diagnosis for this one, you could have just used a stronger battery and got the gearbox out of mid-compression.

You do know that I will buy a stronger battery, I'm just not ordering right now. I took all your suggestion. I'm not ignoring styrak or anyone else. Just so you know. I just did a regreasing while I was there, gearboxes are pretty easy to work on.

I'm used to work on V2 and V3. So heh.
All I can say is thanks for the help.

Edit: While I'm here, would a 9.6v 3600 mAh be alright?

And also, someone just told me that his ICS m4 alway release the spring tension whenever he stop firing.

Yeah that new battery is good. You don't necessarily need a 9.6v but if you want an increased ROF that's ok.

In the meantime if you continue to use that battery it'll keep happening.

Yeaa I know. Tho if it happen again, I just stick a large battery in it and it will fix itself? No need to open it?

I'll look around on cheapbatterypacks for a battery.
And yea I preffer 9.6 for a better rof.
