fastrthnu Posted February 8, 2007 Report Share Posted February 8, 2007 I want to make a relay from the headlight switched wires in parallel to run a cooling fan when the lights are off,. but automaticly switch off when the lights come on. When I get in the trails and ride hard with low speed my bike starts to get pretty hot. In the straighs and cruising its fine, its not an issue, but Id like to keep a fan on it. The average temp hee is in the 80`s too sometimes 90`s in the summer. Or maybe just run it off a small stator charged battery? What do you all think?

375hp banshees Posted February 8, 2007 Report Share Posted February 8, 2007 I'm doing mine soon... csrmel put his fan on low beams & lights on hi beam setting, so you can do all three options... what fans are you going to use? Quote Link to comment Share on other sites More sharing options...
woodro77 Posted February 8, 2007 Report Share Posted February 8, 2007 i tjink you should get a aftermarket water pump , cool head , water wetter or engine ice and you wont need a fan. Quote Link to comment Share on other sites More sharing options...
fastrthnu Posted February 8, 2007 Author Report Share Posted February 8, 2007 Im not sure yet, probly a used motorcycle fan or off another atv. As long as the amperage is equal or slightly less than what the lights draw. Fabricating a shroud will be pretty easy. Thinkin about molding one into a fiberglass shroud. That way I can bolt it up under the same bolts the radiator itself uses, Get a tight fit,. be light, n be trick. Quote Link to comment Share on other sites More sharing options...
375hp banshees Posted February 8, 2007 Report Share Posted February 8, 2007 good luck...let me know what you find. Quote Link to comment Share on other sites More sharing options...
csrmel Posted February 8, 2007 Report Share Posted February 8, 2007 you dont need a relay. the light switch should handle the current provided you arnt running some huge fan off a big block. if you think about it, the banshee headlights dont have a relay, they run right off the headlight switch. if you can sacrifice youre highbeand, or low beams, use one or the other as the "on" for the radiator fan. dont forget you need a full wave bridge diode to convert a/c to d/c. the banshee had a pure a/c electrical system. a/c wont work on radiator fans. most of the bridge diodes are simple to wire up. mine has 2 wires going into it (from the stator) and 2 wires comming out (goes to the fans) it takes a/c in and d/c out. this is a picture of the 1 i use. if you get something like i have you need to mount it on a heatsink. i used a heatsink off a computer processor. nice cheap and lightweight aluminum. the whole setup only weighs about 3 ounces. if you dont use a heatsink you rurn out the diode bridge. one of these days im going to get around to making a couple of how to guides with pictures for the banshee electrical system. 1. how to make youre headlights 20% brighter for less than $10. 2. how to wire up a cooling fan for under $10 3. understanding TORS and how to properly care for it. i just get lazy about it and keep putting things off.

I am interested in #1 and #3. How about you get on the making the how to guides. :yelrotflmao: Quote Link to comment Share on other sites More sharing options...
