Any suggestions? My layout is all Fastrack. On one of my loops, which has four switches. Three switches work fine. However, the location for the fourth burns out switches. Everything runs fine. The only difference between switch No. 4 and the other three is that I had an activator track connected with an insulator track on either side, including one abutting the switch. I have changed wiring on other accessories. At a loss. What should I be looking for and what's the best way to check for problems? Any thoughts?
