I plugged Pikachu into a generator and the thing gets power. If I use the onboard generator, which requires the cab to have the key put to ON position to start up and at least 1/4th a tank of gas, all I can do is get the lights and air conditioner to run. The microwave, TV, and all of that has nothing. I found the hidden house battery and saw it was switched to ON, but alas there was nothing going on.
I am going to check the battery with a tester I purchased and see if that's the issue.
I can already tell this entire thing will be a learning process, but I am excited for the journey.
