Hi I'm Wayne

I will help you with this

when does the fuse blow

using the horn or Hazard lights

Customer: replied 1 year ago.
hi I.. believe the horn... just got this tractor yesterday from utility company... the fuse was blown, front cab lights, flashers or horn wouldn't work... replaced fuse, everthing worked perfect, exept the horn sounded funny. the fuse called for a 20 amp,... they had a 30 amp in its place.. today fuse blew again after trying horn. now there seems to be a dead short somewhere, even with horn unhooked thanks

are you experienced in this specific topic or general? I am at a different location from home, if you are going to be awhile between responses let me know please.

Hi

Thank you for that

Yes I am here

If that fuse is blowing, after the replacement

does it blow when you turn the steering wheel

Customer: replied 1 year ago.
it is blowing with nothing on and just the key on. didn't do that yesterday.
Expert:  Wayne replied 1 year ago.

Thank you for that

there is a wire that runs inside or outside of the steering column

That is shorted rub mark, this is common

Customer: replied 1 year ago.
common on this tractor? haven't seen anything online about that... nevertheless.. have to take steering wheel off?
Customer: replied 1 year ago.
I will go home and try to get it apart. do you know how to check it easier?
Expert:  Wayne replied 1 year ago.

Hi

if you follow the wire into the harness

and feel the harness you will find a warm spot

that is where it is shorting

Customer: replied 1 year ago.
follow the wire from the fuse block? without taking anything apart?
Expert:  Wayne replied 1 year ago.

Hi

No, follow the wire from the horn

Customer: replied 1 year ago.
from the actual horn or the button?
Expert:  Wayne replied 1 year ago.

HI From The horn

and both ways, and then the button

Customer: replied 1 year ago.
absolutely no short at the steering column...is there another testing procedure I should be doing? don't want to be ripping a bunch of things apart guessing at things..
Expert:  Wayne replied 1 year ago.

Hi i

As you know , shorts are very hard to find

you just need to follow the wire harness,looking for rub marks

most common areas are at bends at frame along frame

if you pulled steering wheel and unplugged

still blows, then it is in harness

Customer: replied 1 year ago.
I appreciate your attempt but at this point they are not much help... if I take it into the shop they will more than likely check for ohms through switches or relay, or fuse ports. probably won't tear into the wiring harness first...I really don't want to do that either before testing the appropriate method..
Customer: replied 1 year ago.
if you're unsure of the procedure or where this particular fuse port runsI and tearing into the harness is your only solution ,if you could open it up to another expert I would greatly appreciate it
Expert:  Wayne replied 1 year ago.

Hi

Thank you for that

Not being there we can not see what is going on

Yes, I will opt-out and put to another expert

Sorry I could not help you
