Recently purchased an MTH F40PH railking amtrak set that has the 3 volt ps2 system. Since receiving I decided to change out the battery, so bought the MTH blue battery pack and installed in this engine.
After chanigng the battery and reassembling the engine, I put it on my track at about 14 volts and left it to charge. After a few hours the engine is still showing a dead battery.
Engine starts up has sounds but will not move in conventional and isn’t registered by dcs wi if.
Is it required that you use the external battery charger to get these batteries to work? For some reason I thought you’d be able to charge the battery off track power. I do not have the MTH charger, only external 9 volt battery charger I use for PS1 batteries.
Any input is greatly appreciated. Other than the issues I’m having it really is a beautiful set for the price I paid.
