Chamber fan Circuitry

Unread postAuthor: LikimysCrotchus5 » Mon Dec 31, 2007 3:53 pm

Well after recieving my oreder from bcarms today, i started to get working more on my cannon. I first want to make sure the chamber fan is working so i got it and started the circuitry. it is a 12v DC 3 inch brushless cooling fan from Radio Shack.

So i got it setup up with 2 9v batteries and it didnt work. :cry:

Im not sure whats wrong but a image paint shop will be posted soon

EDIT:

I kno there isnt a switch on it yet but i am just aking sure it works now

Brushless fans are polarized, make sure it is hooked up the right way.

No problem. Remember not to throw your cannon.
