Report to Moderator

Melted the wiring on my 300u today, so am in the process the replacing all the wires. There were no fuses in this system, and my questions are: Should there be fuses? If so, in the wire(s?) between where and where, and what size fuses?
Thanks for any help.

Jimer, yes there wshould bne a fuse hold in the dash. from left to right, the holes are for ... choke, optional cig lighter, fuseholder, light switch, and ignition switch. I believe it calls for a 20 amp fuse. It goes between the ignition bat terminal and the light switch power in if I remember correctly. I dont believe anything else is fused. what wires did you manage to burn? If they were to the gener/regulator, starter/solenoid, those arent fused from the factory, just the accessories like lights and cig lighter.

Thats what I gathered when I made my new wire harness.
Reading the manual tells me the fuse is a 20amp fuse. It also says it only fuses the lighting system, which is how I remember it. The fuse holders can be readily had at most electrical shops and just goes between the batt terminal on the ignition switch and to the backwards "L" pad on the light swtich, not sure what/if its labeled. I can post those specific pages of the manual if you needem.

Jay, Thanks for the info. I believe your directions are all I need to do it right. Everything fried from the ignition switch to the front of the tractor and to the light switch (including the switch). Atleast, that is all I see now. Thanks again.

Today's Featured Article - The Engine Rebuild Kit - by Curtis Von Fange. I always liked engine rebuild kits. They have all the replacement parts for overhauling an engine without going to the store to get gaskets, special measuring tools, or miscellaneous parts. They come neatly packaged, clean and tidy. But it's important not to let that packaging lull you into a false sense of security. The appearance of matching sleeves, pistons, rings, and bearings can cause frustration and agony if not properly measured and installed in a workshop environment. Following c ... [Read Article]
