They were the four that went to the doser, two grey wires to the full switch at the top of the doser and the black ones on the switch linked to the lever.

Also…

There’s quite a loud knock sound when switching the grinder on and off, sounds very much like a relay or similar.

I tried to get a video but it doesn’t capture it very well.

Is this normal or could it be a byproduct of my wiring job…

The noise isn’t that prominent now it’s all buttoned up. To be honest I think my Mini did the same.

On the plus side, got the grind-by-weight setup I always wanted… 😂😂

Walnut bits are still on their way from Wiedemann in Germany but for now it’s dialled in and I’m pleased with initial results.

    I thought I’d ask here rather than start another thread;

    The switch on my SJ works like this - Click on to power on the grinder, then a spring-loaded push to start the motor. Then switch off to stop the motor (which also switches off the grinder).

    I’m guessing the reason for it working like that is because in a cafe it would be left in the on position and the motor would just run occasionally when the doser switch was activated.

    However, now it’s doserless it would be good to have a simple on/off.

    Would it be possible (and relatively straightforward) to change it to an on/off switch?

    @Ernie1 didn’t it already work like that? I converted my auto to simple on / off by:

    • Gently pull on the wires at the microswitch so you can see which ones they are on the bottom. Remove these from the terminal block.
    • Repeat above with the wires at the bottom of the doser. Use a short wire to jumper these 2 terminals on the terminal block. These are all that needs jumpered, NOT the ones that the microswitch went to. (adapted from HB)

    Basically, your grey wires would be disconnected, and your black wires, jumpered.

    Maybe you wired them the other way round?

      Thanks yeah I wired it the way you described and it works well.

      The question above was just a minor thing about the way the black switch on the side works. By default it’s a clockwise click to power on the grinder, and then the spring loaded push to actually run the motor. I wondered if there’s a way to just have it on/off without the sprung part.

        I think I could have jumpered both sets of wires. End result would be OFF - ON -ON (spring). I don’t need to engage the spring loaded ON for it to start grinding.

        I did it like 10 years ago so I wasn’t sure which was which.

        Ah that’s a great help thanks, the functionality you’ve described is what I’m looking for. Just makes ‘topping up’ doses a bit easier if I’m using the hopper.

        I’ll have another look at the wiring, I haven’t had the base off again since I first got it.

          Made a quick video to show how the switch works. See how it switches ‘on’ then takes another spring push to activate the motor.

          I’m keen to have the switch just on/off. I’ll take a look at the wiring.

          Apologies for the video quality, no idea why it’s so bad.

          That’s how mine works. Never had a prob with it really

            I think if I was single dosing it would be no probs at all, it’s just really to make it slightly easier to do ‘top-up’ quick bursts to make up the dose.

            If I do go ahead with painting it I might see about changing the switch entirely to something like the Niche toggle switch.

            Not a big deal at all either way!

              Yeah I’ve seen toggle switches fitted to them, and an Arduino.

                And there’s me thinking that glass hopper would be the last £££ I spend on it 🤦🏻‍♂️

                  I did it because I was concerned repeated use of the switch would ruin it, especially single dosing. I figured it’s easier to replace the wall switch than the Mazzer’s, lol. So I left it on and turn on and off via the wall socket.

                  The wiring on my automatic SJ seems more straightforward. I did not have to open the base.

                    Emc2 I think the “automatic” models have a two positions-only “main” switch - the other switches are in the doser… which you no longer have.
