I'm upgrading to a Sanden, parallel flow, and an oversized fan - this seems like it might be a good modification. Not sure what the current draw on the new fan is vs the old, that's something I'll look into.

The relay gets is own fused power from the large wire that powers the glow plug relay, and that fuse is only for the clutch coil and the condenser fan.
I was providing a 15 amp fuse, but have noticed that it needs to be a 20 amp. I now provide a 20 amp fuse, and it seems to be working on all but one system. If a 20 amp fuse wants to blow, there is a problem with either the clutch coil or the fan. This is the case with the most recent system I did on a friends car. He will be replacing the fan first, and hopefully that will solve the fuse blowing problem. I have had no reports of any other problems with the relay mod.
