M14 Electric problem

[Doma_Tassi]

Hello!

I have a Cyma M14 AEG airsoft gun. But it doesn't work. The motor doesn't make any sound. I've looked the wires with an digital multimeter and i realized the power doesn't reach the motor. The photo is showed. The red circle is where i got power and the green is where not. What is the problem? How can i fix it?

Thanks for helping me!

If you get no power at the green circle even when the trigger is pulled then your trigger contacts are busted.

Is it difficult to fix it home or I have to buy parts for it? I hope You understand what I want to say.

You will probably need to buy a new trigger switch or contact plates for it (I don't know what type of switch mechanism that gun uses). Should be quite easy to do if you can find the right parts though.

Yeah, as Lozart and macko-ricsi said.

Check the contacts and if the trigger moves the moving part at all. You might have to remove the outer assembly of the gearbox, which is not exactly a simple thing on an M14 but if you keep an eye on the little springs (including the one in the safety switch) you should be fine.

I took apart the left side of the gearbox. The end of the trigger switch is sooty, if i clean it part, it will work again?

It may do. Sooty contacts suggest that they are arcing though. What battery are you using?

[Doma_Tassi]

I cleaned it and it works! I use the original battery which is an Ni-Cd and it has got 1200mAh 8.4v. Thanks for your help!
