Hello. I have an MTH F3 diesel from an HO starter set 81-4001-1, and it does not seem to remember it’s address in DCS. I can add and run the engine just fine, but after I shut it down and remove power, it needs to be re-added every time. When I check the engine’s info, it claims it has 0 miles and the “battery” (I know it uses super caps) is low. I used to run the set with the included DCS remote commander and did so for quite some time, so I know the mileage is not accurate. Any ideas on why this may be happening?
