...and I'm loving it. It's directly hooked up to the battery so I need to remember to turn it off or else...It's been really hot here in San Diego so this was def needed. Will I have any problems directly hooking this up to the battery?

 

If you don't have a fuse inline with that switch, then you risk melted wires, or worse, a fire if you pinch the wires.

 

Don't forget to turn it off or you'll drain the battery. Might be better behind
a relay to the tail-light or something to "switch" it off with the ignition.

+1 on IDoDirt's comments, as well. He's the man, and his advise should always
be carefully considered.

I'd say put in an inline fuse, they're like 3 dollars with the wiring and weather protector at radioshack. But I would leave the switch in like you have it, the fans loud enough that you would hear it if you accidently got off the bike and left it on.

 

The switch is a good idea so you have total control of when/how long you have the fan running, but I would wire it through the ignition ON circuit and add the in-line fuse. It would be so easy to forget to turn the switch OFF and you'd come back to a 'flat' battery. I hadn't used my bike for a while and went into town with my headlight on (5 miles away) and when I came back the bike wouldn't start! Fortunately, my grandson helped me out by fetching my 'jump start' machine and I was on the way in no time. You might not be so lucky! I fitted a switch to an old Skoda car years ago and it got me out of trouble until I was able to buy an new radiator switch. I left the wires and switch in place so I could use this system again for insurance against another switch in the radiator going bust!
