There are lots of old diesel generators out there. If you get some info from the set we can have some fun. There are other sites that cover this stuff better than here but now we need an answer here.
Many years ago we visited Scotty's Castle in Death Valley. The house tour was good but since we've been making our own power here since 1972 the tour of the Power House was way more interesting to me. There were a couple of gen sets with engines but the main one was water driven from a huge spring above the ranch. It was hard getting me out of there.
