G36 Wiring, Weirdness.
 

Well, i just got a new swich/wiring assembly from airsoftparts.ca. They were out of stock of the G36 wiring assembly, so i went with an AK 47 wiring assembly. I installed it, but added about 5 inches of extra wire in the middle to make it reach all the way up.

When i hooked up my battery, it fired once in semi, then stoped.
I tried a different battery, same thing, so i double checked all of my wiring connections, they all looked solid.

Ideas?

Brand of wiring assembly?
