What gauge is the wire running from the coil to the distributor on a Ferguson TO30? I bought a wiring harness, but that one was not included.

A 14 gauge wire is clearly big enough, and of a sixe that is wasy to fit terminals and solder. Use shrink tubing over the soldered connections. Jim

As Jim says 14 gauge will work just fine and it is even over kill. 16 gauge will also work but me I like over kill when I wire things up

I agree with the other fine gents and as the current is likely 4 amps or less at such a short distance 14 Gauge would suffice and its just that bigger wire has more mechanical strength and fine stranded copper can withstand vibration better

i, John.....good thing you 3 guys are not wiring Boeings....they would have to remove some seats if all the wiring was so oversized.

If only 2 small strands, what is one seat compared to a wiring fire that causes a uncontrolled encounter with terrain? Jim

ith miles & miles of wiring on those big boys, believe me, they look to save every pound, even down to the selection of insulation material type & thickness. Sometimes a bit scary.

Hey but were not wiring Boeings !!! It's NOT ONLY wire ampacity and voltage drop I would consider but the MECHANICAL STRENGTH. While 16
Gauge would more then handle 4 amps of current, I would still use 14 Gauge wire for the short distance from the coil to distributor since
such a teeny tiny hardly measurable weight difference in say 14 versus 16 gauge wire doesn't matter in a 3000 pound tractor. Often more
weight is added to a tractor for increased traction anyway, even MORE reason to use heavier wire lol

Take care, its always fun chatting with you

I put a smiley face on it! I guess, for some, I needed to say Ha, HA, Ha, laugh, laugh, laugh!

And remember if you get on one, it was
probably built by the cheapest bidder! Lol

Use MTW it is much more flexible than THHN
