@texgeekboy posted:I'm with @Chills, a pic is worth a thousand words, especially for the electrically illiterate such as myself. This is a picture of the motor area of my brand new 6-18565. My guess is to solder on the tvs diode to the 2 circled contact points. Would that be the proper thing to do? If not, what should I look for? Also, if the diode is connected directly to the engine, do I need one connected to the track? I was planning on connecting diodes to each of the 4 posts on my ZW, along with adding a circuit breaker.
Thanks.
Wrong, that's across the motor armature. The TVS diode wants to go across the track power inputs to protect the electronics. The motor driver outputs are designed well enough to deal with the transients coming from the armature, and that's also what the 1.0uf blue caps are for.
EDIT: I see Steve beat me by a few seconds.
