Hi Scrambler82
First to hopefully put the wiring to bed I have corrected the wiring as you pointed out and then attached two images here, one being what comes with the speed controller.
I mounted the fan on top so I can see if it is running. It is very quiet, especially at low speeds, so I think it is better to see it moving. But thats the only reason. I'm sure others will modify as they need. Another question from someone was about using a manual blower, and of course one could be substituted. I found it hard to locate a manual blower. I bought the electric blower on advise from my teacher and mentor Trez Cole (Nokomis forge) who has used the same. I must admit I think its really good. I have actually being using anthracite coal and love that the blower at low speed keeps the coal at a nice steady burn.
Cheers - Tony
