*** Actually live frogs properly wired are the best for sound - and all running in general... but that means live frogs with switched polarity.

I get the sense from your post that you actually perhaps have insulated frogs with point clips? There is no other logical reason to be using paint to insulate the frog tips.

if not, tell us of the track brand and how you have wired the points.

*** I see you have received several responses all with helpful info. Looking through them, if the problem is at the frog, then that flangeless wheel may well be the culprit with the pacifics, especially if you are using set-track or small radius points. If the problem is wheels crossing the gap between point rail and closure rail, then back to back adjustment will help it.

You really need to get down lose to the point, with the light dim, and drive the train into the point at a slow but not too slow pace. You will see a small arc as the short happens if it is a short.... If no flash, turn the lights up and repeat, watching closely to see where it stops. note which wheels are where ant it may help you narrow the problem down.

Also helpful to understand... Does the problem happen in both point directions, or perhaps more on points immediately after a curve?
