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.
