Henry---the local junkyard doesn't give spec sheets. They tell you what the fan came off of and charge you $25. If it don't run, they might give your money back, on a good day. I know that all over the world there are hotrodders with 15" electric fans setting around their garages, collecting dust.---I was hoping someone could do what I just did---hook one up thru an ammeter and a 12 volt battery and tell me what their results were.
