While that may be true for the first few years, age does matters. The NI-CD are beyond there useful life at this point in time. Especially if they are original to the engine. Usually when measured they are in the 6-7V region, if not dead. Enough to continue to operate a PS-2 but a load on the charging circuit and power management Chips. For what ever reason the older batteries do die quicker and they also can leach out corrosive material.
Frank, At this point in time, the PS-2 5V boards do have a tendency to work one minute and die the next, with no apparent cause.
I don't know if you resolved your issue, but worth checking your harnesses and connectors, also the speaker wires. If there is an MTH tech in your area he can test the board for you.
I had a similiar repair with a PS-2 that was not operating correctly. The battery was dead and also had started to leach a corrosive grime. I removed it and installed a new one. The engine started fine on the test bench. I shut it down and reinstalled the board bracket screws.
I went to test it once more before installing the shell and it was dead. Removed it and placed it on the board tester and it was dead. This happens. This was done on an electronic work bench certified for electronic repairs.
I am interested in hearing if you could reset it with DCS, or whether it is permenatly locked in FWD. G
