Re: Bosch SGS5302 Dead or just Resting?

Hi Penguin45

I’ve had a look at the cct board and 1 of the contacts on the large NAIS relay was dry. I have re-soldered it.

I get about 400 ohms through the coil of the relay, which is about right when you look at the spec for this relay on the web. I also get a reading on the NC contacts.

I put it all back with great hopes, but its still as dead as a Dodo! 🙁

Are there any other fault conditions that could cause this fault? I’m pretty sure your right with your first diagnose’s that the control board has blown. 😥

Thanks Paul

Hi Bob

As you say they have their place but don’t trust your life to them! 🙄

I would not advise anyone who does not have the proper training to work on live equipment.

Any ideas welcome.

Cheers Paul.

Hi Penguin45.

Thanks for the concern for my safety, I am certified to work on live mains during my normal day job and appreciate that many non technical people read the forums. 8)

The door was fully closed, as you say the handle linkage is a safety feature and cuts the mains to the cct board when opened.

I haven’t taken the cct board out yet, that was going to be the next step. Reading through the forum the boards do seem to be prone to burning out tracks!

A meter and a good cct diagram can solve most problems

The point I was making, very badly, about the mains sensing screwdrivers is that you can test for mains without actually touching anything.

Thanks again for the advice

Cheers Paul.
