CTW Issues :-S

[FULLMETAL]

Hi guys,

A couple of weeks ago I got a receiver with issues. It works randomly fires some shots and stops firing. After leaving it quite for some minutes changing selector position and playing around (removing battery will help to) it fires again, but after some shots it stops... Again.

So I thank that the ECU was fucked up so I bought a brand new ECU from Etiny (the Celcius one). But after installing the new ECU I got the same results. So definitely the ECU is not the issue.

I dont have spare parts for testing, and I dont want to buy another mosfet and another motor so see which one of them is done.

So here is the question... did anyone of you had this issue before? Was it the motor or the mosfet?

Is my third CELCIUS gun and I never had issues with them before, so please if someone can extend me a hand here will be really appreciated.

In all probability its your mosfet. If your motor was the problem it generally wouldn't spin at all.

Either that or with the empty mag detection. It thinks its empty (loose piece?) when it's not.

I know is not the empty mag detection, so must be the mosfet, well at least now i have a spare ECU.

Check your selector board, it happened to an CTW I was working on. The selector board nubs were worn down so sometimes it'd make contact sometimes not, exactly the same thing you described.

Definitely not the motor because it wouldn't fire again unless you spun the motor or fiddled with the gears, so you can cross that out.

Most likely not the mosfet either because you can fire again and again, unless its starting to fail, then you need a new CTW mosfet. I might have my old one laying around somewhere.

Bad battery?

It can cause this same problem by activating the low voltage cutoff in Gen 4 PTW.
