Hi All,
Galco Repairs,Global Electronics Service and many well known repair companies experts directly changed Relay, Opto-Isolator even they found good after load test. The reason for that is these components work very frequently and in high speed switching in UPS or other Types of Inverters.That is why their repairing is not just repair but refurbished equipment.

Hi Humberto. nice repair. Thanks! I also liked the post Chris wrote about testing relays. It could be a very handy tool as DIY relay tester project! Indeed Relay contacts tend to get bad after many high current switching moments. The only way to normally be able to see this, is to open them. With the solution of Chris you don´t have to.

Hi Chris 110v/60Hz in my country, the 98v is due to a new Baterry, remember it had to be charged first, that's why the 98V. When it was just repaired I performed that measuring with my DMM.
Thanks anyway.
