8n fuse protection?

mike paulson · Jan 17, 2011

hey fellas im going to be doing some rewiring on my N and was wondering what circuits need fuse protection? i was planning on using waterproof inlines and it is a 6v system so what amps should i use for these circuits.
will have headlights and thats about it...

The only fuse you need is for the lights. The OEM switch has the fuse mounted on top of it. 20a afaik.

Do not wire the lights through the ignition switch! Make sure the light wire has a quick disconnect in it for removing the hood.

BTW, you'll find it a lot easier to do if you just buy a ready made harness.

Replace the terminal block & the ignition switch & it will be totally rewired.

No need to remove the hood, but removing the tool box & air filter makes it an easy job.

Mike,

That's a personal choice, of course...but my choice would to NOT put fuses on.

I have an inline fuse at the hot post[-]of my battery.It has a 30 amp blade fuse just like a car has,and would only break in case of a catastrophic failure somewhere,like a short or malfunction of the charging system.---lha

I added an in line fuse at generator with an amperage just above "maximum output", but small enough forwire size. I also added an in line fuse to coil. My original on off switch has an ignition and an ignition-light, so I routed the wiring thru it and added a "circuit breaker" in the lights.
All of the above is because my previous ownner added a 12 volt alternator an the wiring burn up.

I agree with GVT in it being a personal choice and with Bruce 100%

ditto what bruce said. fuse the lamps for wire safety and laod.

20a usually does it.

When I rewire older stuff I typically use a length of appropriately-sized fusible-link wire at the point where the electrical system meets the battery (at the starter solenoid or switch) and one at the alternator. (As newer vehicles have used for MANY years.) They will carry a momentary overload and NOT blow instantly as an automotive fuse does, yet offer protection when something does "go south". Ready-mode links or generic lengths of fusible link wires are available at any REAL autoparts store.

Check out the link below and read about 3/4 of the way down to see the benefits of a fusible link over a fuse in a heavy-duty circuit.

Ignition and lighting circuits get a fuse.

Are the waterproof "inlines" you intend to use of the flat blade "ATO" type? I've found them to make better contact and be more reliable than in-line glass automotive fuses.
How to size fusible links

John (TR) · Jan 17, 2011

size the wiring for the load, the fuse protects the wire. I'd fuse the headlights. If you convert to an alternator I also throw a 30 in line with the output of the alternator just becasue. On my 2600 I had 1 circuit fused at 15 amps for external lighting as it had a number of headlights mounted as it was my snow machine and a second circiut for all my electric gages fused at 10 amp and a 40 amp fuse on the 60amp alternator, wiring size acordingly #8 40 amp #10 - 30 amp, 12 - 20 amp, #14 - 15amp #16 - 10 amp is what I go by which may be a little conservative.

or the most part John you are correct. Distance run factors into it, but on these little tractors your little rule is AOK.
