I know electric fans aren't traditional but my otherwise traditional car (see avatar) has one due to a series of rookie mistakes I made when building it pre-HAMB. So, big ass pusher fan. Works fine EXCEPT I bought a fancy controller that is supposed to turn it on at half speed at one temp and then go to 100% at a higher temp. Sounds great in theory but it is not really working out. No matter how much I adjust it I get 100% fan too soon OR no fan when hot. I'm ready to ditch the stupid controller and just hook up a manual switch. Now to my questions: can I just run battery + to fan (it's already wired this way) and use a heavy-duty toggle switch to ground the fan? I would just be replacing the fancy-ass controller with a manual switch. Where would I put a fuse?
