" I have followed Marcus Ammann's guidance,
and can measure 12V D.C. from the bridge-rectifier diodes to the function common,
but connecting the 'Keep-Alive' this way, only keeps the headlight on, not the motor."
Arh ... yes ... I just read this again.
The 'Stay-Alive' would need to be connected BEFORE the bridge-rectifier & capacitor.
The motors +/- polarity in 'old skool' D.C. operation, changes with loco direction.
I have never fitted a 'Stay-Alive' to anything before & know little about them.
Do they have some kind of rectifier diodes of their own in there ...
... to protect the 'Stay-Alive' from reversed polarity & damage ?
This is a circuit schematic for a 'DIY' stay-alive & there are NO protection rectifier diodes.
