The Zimo Stayalive controllers are a great solution for DCC model railways, where the DCC decoder is more sensitive for loss of power.  So please note that this only works on digital model railways in combination with a DCC decoder. You can use any brand of DCC decoder, it’s not only Zimo. Just connect the blue wire to the Plus (or blue wire) on your decoder and grey wire to the minus (or ground). Don’t confuse the grey wire with the grey wire for the motor contact.

You might have to change CV 29 to disable analog mode, to get better performance. Normally that is changing value 14 to 10. When you leave analog mode on with for example the tOm Lokommander II decoders, the motor will suddenly spin faster when track power gets interrupted.

Below connection example to Train-O-Matic Lokommander Micro decoder. With the Mini decoder, the blue (+ VCC) and grey (GND) wire are swapped.


If you want to replace the default supercapacitor of a Powerpack of any brand that has a Powerpack connection (the 3 wires solution)
