@texasspeciallionel posted:Thanks for the info, do you have a picture of the airpax wired in? I'm trying to figure out where to put them. Also, on the diode, do you recommend placing them directly on the ZW posts? I'm using fastrack, where do they go on the track?
If you follow this link AirPax Instant Breakers there is a diagram showing how to wire these breakers and the TVS diodes. I also use postwar 275 Watt ZW transformers with these breakers. The 10 Amp model is a good choice for these ZWs

The TVS diodes are intended to protect the electronics in your trains and the closer these diodes are to the circuit boards, the better they protect them. The best place is inside the locomotives connected to or near the circuit board where track power goes into it.
