CTW Problem

I noticed my battery was dying on my CTW..I plug a new battery in and nothing no blue light so I throw a new fuse in it and still again nothing any possibility to what could be the problem? ECU maybe not sure.

i think it is the power unit that is at fault. i had this problem before and i replaced every single electronic part with celcius oem and it STILL did not function well. i wasted over $200 including shipping. Here is my suggestion, buy a systema ptw 490a motor and etiny ecu and power unit and the gun was working PERFECTLY. keep the gearbox it is pretty decent

If your getting no blue light then its probably your MOSFET board in the stock thats at fault OR have you managed to 'knick' the 4 control wires that run from the MOSFET to the ECU?

Thats probably the cause - the motor does not influence the blue light at all....
