In the past month, two of my PS2 locos (both retrofitted by me after gutting the original Proto-1 boards) have both stopped firing one of their two couplers.
The couplers themselves don't appear to be damaged, but we've had our share of 'hard' hookups over the past couple years.
The sounds still work when firing the coupler, but there didn't appear to be any activation of the coil at all (no clicking, sounds, etc). I've checked for continuity across the coil points, and they ring out. So I'm worried that something on the boards is going bad.
Both of these have 3V PS2 boards. It's there a component on the boards I could check somehow, or am I out of luck?
