Good question. I should have made note of it. It was a 20A fuse. My memory tells me it was the second from the right, and that it was under one of the 30A fuses. However, if I look at the diagram I found online, that doesn't add up. My memory of the fuse placement on my tractor is that the 30 fuses are in positions F4 and F5, and that the fuse I replaced was F8. The operator's manual here: OMLVU24810_D1
Is consistent with the image below, although the numbering is different. So, my guess is that I replaced the one labeled as F7 in the "Load Center" diagram, and F05 (Ignition Run Power) in the manual. I'll try to verify that this evening and update this reply.
