I'm installing a Tsunami 2 TSU-PNP 885014 sound decoder in a remotored Athearn U-28B. The decoder has a plug for a Soundtraxx Current Keeper. I have a capacitor on hand that I'd like to use instead. Trouble is, I can't tell which lead to the plug is positive and which is negative. Any advice?
Thanks
Don't forget, any stay alive has a diode and resistor with the capacitor also.

Just identify the positive and negative leads on the connector. Do some tracing.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
Positive will go to the same place as the blue function common wire.
