Driving my L2800 down a dirt road, everything dies, 40 amp link fuse at battery that says Key Switch is blown. Wiggle all wires I can find put another one in. Runs awhile blows again. Now has blown three and wiggling does not seem to help. I know I have a dead short somewhere but can't find it. Does the wire from that fuse go directly to the key switch? Can I take the center wire loose from the key switch and run a wire directly from the battery to the center of the switch to get it home? Tractor only a couple of years old and all the wires are encased. Makes it hard to track them down. Thanks for any advice and help.
