I recently had a few illuminated Kato bumpers (n scale) get hot and burn out. I did notice that one of them got melted underneath the track at the led. The 2 others stopped working. All of the tracks in question are insulated from each other except at the power blocks. The wiring has been done months ago and we have been running it without problems until the other night. The only thing we recently did was use a static grass applicator to add grass to a small section. Could this have caused the issue?
