Well, I got the speedometer working and calibrated for kilometers O.K.----one wire had come off its terminal under the dash. I am still not sure with the fan issue---I jumpered out the fuse with a peice of #14 ga wire and let it run for half an hour. The wire got warm but not hot, and remember the rest of the wire in that circuit is #10 gauge. All the parts stores are closed here for Canada day, today, but tomorrow I will definately find a blade type circuit breaker with a delayed response time and try it. When I am going down the road this engine runs at a constant 180 degrees, and the fan doesn't try to come on. It's only after setting for 7 or 8 minutes that the temp creeps up to 190, then the fan comes on. The fan only has to run for about 5 minutes, and the temp cools back down to 180 and the fan shuts off. I watched this fan cycle on and off in my garage for about 20 minutes, and everything seems to work perfect, with the fuse jumpered. This fan appears to be a 2 speed fan, and right now I have it wired for the high speed setting. I may try wiring it for the lower speed setting, and see how this affects the fuse.
