Morning Torch, I have seen several of your post about B7100 tractor. I have a B7100 HST-D purchased in 1996. The tractor is in perfect condition but in central Texas I am considering building canopy and would like to install a cooling fan in the canopy. I have seen several on the forum have used a radiator cooling fan. My question and concern is will the dynamo produce enough amps for this. I do not use any lights on the tractor or any other item which I know of that would be drawing amps. Would appreciate your thoughts. You may email me at wilburncox@embarqmail.com or PM me someway on the forum. Thanks in advance for your assistance and have a fantastic day. Wilburn"Red" Cox
