Stay alive

Jay Beckham

Kelly and others

Do know of a stay alive for these QSI in my two Atlas Gold series O Scale
GP9 engines? Or perhaps a homemade one such as including in last month's
issue of Model Railroad Hobbyist. They (Joe) used four Supercapacitors, a
diode, resistor, and a Zener diode. The Zener was to cap the voltage to 14
to protect the four Supercapacitors.

Attached is photos of the decoders.

Good question, and I would love to know how to fit stay alives to all my BLI HO locos too.
