How To Fix An Electrical Outlet With Surge Protector Built In Repaired
A customer brought this surge protector for repair. He has sent it to someone else and was not able to get it fixed.
When I powered on the device the red Light should come on; then it should go off after the green light come on when the relay clicks on.
I did not see the light switching and the relay did not click.
That is a closer look of the device. It is not an expensive device but the customer wanted it repaired.
I took the cover off exposing the inside board and my main suspect was the relay which is the black part on the left side of the photo.
Here is a closer look of the board and I do not think I have such a relay in my shop so I have to look for one but let us test and make sure it is the relay that is causing this fault.
This board was re soldered before and as the customer said this device was sent to another tech for repair and that tech assumed re soldering the pins will bring it to life.
I should have tested if this relay gets the right voltage to operate on not but I de soldered it off board for check up.
It seems a very good relay and it should be easy to take that cover off to see if the inside coil was faulty since I was not able to get any ohms reading on it.
And as expected one of the coil side wires was loose and needed to be
connected to work and that is what I did since I do not have the right replacement for such relay.
I soldered the relay back on board and tested and as you can see in the photo, the green light came on after I heard that relay kicking in.
To make sure that this device is up and running I measured the output on the outlets and sure enough I was getting the right voltages there and to that I could call this job a…
Mission Accomplished.

Good job! It may have been not such an expensive device but most really cheap outlets have always screws that can't be screwed out. With screws that only can be screwed in at assembly. Or no screws at all.
So I suppose it was expensive enough like the Fluke DMM you used here that is known for being quite expensive.

Albert: thanks man. it is way less expensive than my Fluke meter that is for sure. yes to the customer the device was cheap but was worth the fixing since it protects the devices that connected to it. have a blessed day.

It looks like an extension wire to me,and looking at the board I guess its power output is DC.Thanks for sharing.

Imoudu: yes, it is an extention wire and no the out put is AC not DC. the voltage meausrment were in AC up to 220 AC volts. have a blessed day

Yes it looks like the main coil wire. Smart going on opening up this relay to make this an easy fix.
