My fan doesn't work. The fan motor works and the relay works however, the big red "always on" power wire isn't getting any power to it. When I grounded that wire with a test light, nothing happened, so there is no electricity running through it. My fan fuse is fine in the main fuse panel. I ran a wire from the + terminal of the battery to the black and red wire, and the fan turned on.

Can anyone tell me if there is an inline fuse anywhere on this red wire?

Can anyone tell me where this wire hooks up to the power source?
