3901 "quit"

[lucky pierre]

was operating when the engine just quit - there's no indications of anything on the dash when the key is turned to "start" and there's no cranking of the starter - appears that no electrics are getting to anything - any help for me out there ? thanks

re: appears that no electrics are getting to anything
that sounds easy like..

1) main slow blow fuse opened ?
or

2) battery cable fell off ?

best to have WSM for the wiring diagram !

Could be any number of things. Time to do some poking with a test light and/or multi- meter and narrow yhe field a bit.

How old or young is your L3901?

Under warranty? If so, call your dealer.

my Tractor is a 2017 and it's in my fenced backyard so it can't be towed from it's location so as to get it to a dealership. having a hard time finding a Mobile Tractor Repair Mechanic and it's a problem above my capabilities

Inquiring minds want to know. How did it get inside the fence?

Just about any mechanic or mechanically inclined friend can do some preliminary diagnostics to rule out the simple things. If it turns out to be something simple (bad battery or connection, blwn fuse, etc.) ) no need for the high dollar guys.

If you have NO lights coming on the dash when you turn the key on, no headlights, no turn signals you have a simple 'electrical' problem.
Any 'small engine mechanic' should be able to find /test/replace the blown 40 amp primary slow blow fuse.

thank you Sir, for the reply - as I was simply driving the Tractor to a location and it suddenly just "quit" running - "twas then that I discovered that "nothing" worked = no starter crank, no dash indications, no lights, no nothing.....could the Slow Blow Fuse blowing be the cause of this ? If so and I'm no mechanic but I will look for for that Fuse and do you think a layman could remove and replace it ?

The workshop manual for the L3901 can be downloaded for free. It contains a wiring diagram and some basic troubleshooting procedures:

Based on your description it appears you experienced a total loss of electrical power while operating the tractor. Those types of sudden catastrophic failures are usually easy to diagnose.

If the main power fuse blew there is a reason for that. Simply replacing the fuse is not likely to fix the problem and you can expect another blown fuse.

I own an L3901 and I will take a look at it and the manual to see if I can get you started on the easy stuff.

In your post #5 tractor was " in my fenced backyard".
In your post #8, you were "driving the tractor to a location".
Confused: Is that "location" also inside your "fenced backyard"?

Here are the two primary fuses on your tractor - the blue and purple colored squares in the lower right corner of tje picture. Just open the hood to get to them.


They simply plug into the holders and can be easily pulled out, tested, and replaced if needed. As I said earlier if one of them is blown there is likely a problem in the circuit and a new one is also going to blow.
