CA m15 motor issues?
got a CA m15a4 in for a friend today. hooked up a battery, and the motor turns, but gun doesnt fire. so i turn in the set screw, and nothing works.
I start dissassembly to find the problem, and the motor is jammed so far up the grip, i cant pull it out. motor issue fixed. BUT, now it doesnt work at all. I can hear the motor begin to turn, then lock up.

make shure that its set right, and that the gears wernt dammaged,
and i know this sounds like an idiot question, but did you make sure you put the leads back on correctly? the red goes on the + side

It isn't hard if you give the trigger a couple pulls to test it out each time. Anyways thats beside the point. Crack your mechbox open if you're comfortable doing that kind of work.

well... this gun is a barrel of fun. Among the stripped threads ill have to re-tap later on, the wiring is backwards. the battery plug had the wrong shapes on the wrong sides. brilliant.

your right. never as an electrician for advice
 Now, it cycles once, then locks up.... the situation is slowly turning good. any suggestions?

Just an update: this thing is alot of fun. Ill have to replace all the wiring inside the mechbox, its full of stripped insulation. It has temporarily been shrink wrapped.
Shimming was horribly horribly done. Ya, the gear to gear placement was nice, but the gearbox to gear ratio was horrible. i could barely squeeze the mechbox together with the gears in, and the gears barely moved there was so much pressure on them. it has been reshimmed properly. Gearbox is still jamming up at the spring's most compressed position. It was suggested that an aftermarket spring was installed that was too long, ill be swapping out the spring/cylinder assembly to test that theory.

how long is it? cuz i dono how a sniper spring would even fit in it,
it still could be shimming, how many shims did you use, if its over 8 its prob to many, theres only 5 in mine |

its probably not the spring, but rather the travel of the spring is too short. my bet is on this funky spring guide, nothing like ive ever seen. ill try to dig up a picture of it. it has a huge plastic "bushing?" on it, takes about 1/4" of space away from the spring, enough for me to assume the spring reaches its full compression before the gears can rotate enough to the last tooth, thus jamming. I dont have a regular v2 spring spring guide to test this theory.
Can anyone confirm that CA stock spring guides do not have a huge-ass cylinder surrounding the guide? Anyways my bets on that. Shimming I may check again, although im pretty happy with it as ive rearranged it.

Dude, I just saw this post...I've got a complete stock CA piston, cylinder, spring and spring guide for an Mp5.
I replaced the stock internals with a Hurricane 120 upgrade kit. You're still going to FNG day tomorrow?

G&G used to make a black spring guide with round steel tabs to lock it in the mechbox shell. They used a plastic spacer about 1/4" thick, made out of the same black plastic, most likely ABS or similar polymer.

Kev: ya ill be there. ill bring the m15 just for kicks.
Mcgyver: sounds like thats the win there, pretty much exactly describes it. G&G and CA probably dont mesh together 100%.

take the plastic thing off, but it should have worked anyway. my CA got upgraded by someone else before i learned how, a long time ago. so i don't have any info on what its supposed to have, but mine now just has a thin piece of metal, the thickness of a shim, around the guide, and it works just fine
