O.K. Guys---The reason that I'm dickin around with relays is this---I met a fellow in town here with the sweetest 30 model A closed cab pickup that you ever seen. He bought it as a roller with a busted Ford 302, and bought a 350 G.M. crate motor and 350 Turbo package to install. He is a nice guy, but he isn't real up on automotive wiring, and the old Ford motor ran a mechanical fan. He wants to run an electric fan with his crate motor, so asked me about how to wire the fan, where to get the thermostatic control switch, and how to wire it all as a package.----I just went through all this with mine a short time ago, so I am helping him out. The post about relays was just a "general interest" post.
