HK T-90 Recoil Canon issue and Broken Machine Gun LED.

[brucektrain]

Just kinda finished the T-90 Right now. Still not installed the Metal Track yet until the axle support arrive, same for the Red Eye modifications too.
Just installed the 360 degree Kit and Recoiling Canon. The Recoil canon works. but after some time, it's start going recoiling loop couple time before making fire sounds. i think something to do with the trigger?
And we having issue with the machine gun led which not flashing. so probably broken it during process of installing the recoil canon upgrade. I think it's 5mm led diode. but I've found in amazon which has 5mm LED diode 30 pieces with wires already. (for 8AUD - 12 Volt 5mm Red LED Lights Emitting Diodes Pre Wired 7.9 inch DC 12v LED) - Need looking to replace with new one.

I did got diagram for the wiring for the red eyes from the seller in Ali Express. (Or Does someone has simple or image guide something similar or better than theirs guide?)

Check the manual 1st as you may have inadvertantly switched it off (pretty sure theres an option for that)
