In-Line Fuse

Johnny Lawson · May 13, 2009

Could I install two 20 amp in-line fuse's coming off my ammeter...one fuse running to the ignition switch and the other 20 amp fuse running to my lights? Or could I pigtail the ignition switch and the lights together on one 20 amp fuse? There is not much room on the ammeter trying to put three wires on the ammeter terminal...espically with the alternator BAT wire. Any suggestions would be most helpful?

If you want to fuse the ignition circuit I'd supply both the ignition and lights through a single 20 amp fuse.

However keep in mind from the factory the only the light circuit was fused. I expect this was done so a blown fuse, worn out fuseholder, busted fuse cap, etc would not leave the tractor stranded miles from the barn. (You might drive home in the dark, but it beat walking!). Also, unlike lighting circuits a short circuit developing in the ignition wiring is extremely rare.

Were the tractor mine I'd fuse only the lights...

A coil ignition will draw around 4 amps and the lights may be in the 5 to 12 amps range (I just cant say sitting here not knowing how many lights or the lamps wattage).

Soooooo you can likely get by with a single 20 amp fuze to run BOTH lights and ignition... (again it depends on how many and what wattage lamps, but if its original with 2 regular original type headlamps and a tail light 20 amps should handle all that.

However, if you insist on fuzing the ignition and lights seperately (2 fuses) Id fuse the ignition at 15 amps n use 14 Gauge wire and probably the same for the lighting circuit unelss the light wattage exceeds that which I doubt..

A single 20 amp fuze would be simpler and should work unless you got all sorts of lights everywhere lol

Factory was 1 fuse right below the amp meter. Lights only.
