I recently wired the fan switch to power direct from the battery when it is turned off.

I used the inline fuse rated at 10amp.

However turned it on and off a couple of times to test then the fuse blew.

Never had an issue when I was using a tapped "on" ignition source.

I thought the fan had a 7.5amp fuse from the factory?

Do I need a 15 amp inline or should the 10 suffice. (Not strong in knowledge in regards to this)

Cheers
