I came home today to 151 degree water and the damper at 100% but no fan running. I checked voltage at the fan plug and had 0. I pulled the control panel and found a blown fuse number 1. Hmm. I left the fan unplugged and replaced the fuse, now I had power to the fan plug and the fuse didn't blow. I started inspecting the fan wiring and saw that when I had reinstalled the retro fan shroud that I had caught the power wire and pinched it. Whoops. I cut out the pinched section and resoldered and shrink wrapped it. I plugged the fan back in and it started right up. I should know to pay better attention. Oh well, easy fix.
Don’t feel bad, within a week of upgrading combines and grain heads dad had a slight “issue”, least thats what he said when he called me.
You have a PTO shaft on the head with a 21 spline coupler (1000RPM on a tractor), three hydraulic hoses, the latch itself and an electrical harness to unplug before setting it on the head cart for transport. He got everything but the wiring harness disconnected and forgot about it, backed away from the head and the harness didn’t stand a chance against a 25,000lb combine. Real cute plug too, looks like a standard 7pin round trailer plug like a semi uses, except then they managed to squeeze another baby pin or socket between the large pins and sockets then another four pins and sockets around the center terminal for a total of like 17 potential connections. Was a real joy to disassemble then reconnect all the wires.
