Will the original fan speed switch work OK?
What size fuse should I use? The fuse that was in it appears to have been 14 amp. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | it should do fine Bob, higher voltage, lower amps - but do expect it to get hot, that's how they do their job on any voltage .... the 12V systems use a 10amp fuse, so you could cut back a bit
Bill | | | | | Joined: Jun 2012 Posts: 1,749 'Bolter | | 'Bolter Joined: Jun 2012 Posts: 1,749 | The 6 volt speed control should be fine with the 12 volt motor. And an inline fuse is a good idea. The change from a 14 amp to a 10 amp fuse sounds about right as well. But.. the wire you have is rated at 14 amp so there is no real need to change if you don't want to. The 10 amp fuse might, just might offer a bit of protection to the new motor. The rest of the system will be just fine if the wire and switch are in good shape.
