Baldoc posted:I ran the tests and the coil appears to be the culprit. I have extra coils from old E-units that look like the same size. Can one be used as a replacement, or do model train coils vary in voltage and current requirements?
When you say bad, is it open (infinity) or shorted (zero or close to it) ?
If open its likely broken near the connection. Like Tommy says, it can be repaired.
If shorted it will be obvious with burned insulation. Time to toss it.
