Hi Guys,
Trying to finish an old project, and I have a BR111 that I have fitted the 60973 pick up shoe change over board.
I also wanted to fit the Märklin buffer capacitor, but it uses the SUSI port normally and the 60973 doesn’t have a SUSI port.
Can anyone supply a diagram showing where I can connect the individual wires to bypass the SUSI connection?
Cheers…..
Mike

Moved the interior lights to F2 on the function decoder and appears all good.

Normally Aux3 and 4 need to be always on, in forward/ rewerse mode ref manual, so it's sensible not to combine those with other functions. (On my mSD3, I used logic on the aux 3 and 4. So I can "lock" the relay in one position and only use one pickup shoe). A little tip is that if you don't need the chassis/ground to be switched, you can bypass the relay and use the 0/GL pad next to the 3 GND solder pads.

When you say bypass the relay, do you mean that normally it switches both the slider and chassis? Could you please clarify?

It's just a minor thing, but yes, there is a relay on the chassis connections as well. ref the relay diagram on the board and the manual. And using the alternative chassis solder pad bypasses the relay.

Maybe F3 sets shunting speed
