As others have pointed out, sounds like a short. First step is to make a working copy of the wiring diagram. You will use this to mark good and bad circuits with different colored hiliters. Second step is knowing that the fault can be isolated using the tractor fuses and harness connectors. I...

Some probably are related, but... Make a workable copy of the wiring diagram. Get some colored highliters so that you can mark good or bad on the wiring diagram copy. Take off the ignition switch so that it is isolated. Use a tester with light indicator and manipulate the switch to check...

Nothing problematic with Kubota connectors. They are Japanese motorcycle connectors which is the clue for finding replacements. In twenty years, the move has been to sealed connectors for automotive. But one can still get the old style if wanted. If you decide to build a new harness you can...

Bastrop I can offer my own experience digging post holes with an L3800. Soil here is cohesive clay. One thing to note is that the 3-point attachments are on a chord determined by the arc of the hitch. Ideally the tractor should be parked so that the auger shaft is plumb when the auger is close...

L5450 No worries, you are doing fine. Everyone on this forum can see the posts, it's not one-on-one. Posts are searchable and they do help more than the original poster.

"The cylinder block and cylinder head are cast iron. " Sorry for not conveying that idea properly. What I meant was that things have changed for those of us who are old school. Techniques that were used in days past do not work well with today's machines. Gaskets are one of those. The material...

I agree that it is likely that the head has cracked. When these engines overheat they need correction immediately. Continuing to run until overheating, just overheating a little and not even busted needle on the gauge overheating, the cumulative result is a cracked head. Make sure to know how...

Referring to the last picture, the two nuts allow the switch to be positioned forward or backward. That would be the quickest before bending or replacing the bracket.

Welding may not be the only option. Search this forum for freeze plugs as this issue has been covered before. Different kinds of plugs to fix this issue.

Sounds like a possible classic rebuild problem. Take off glow plugs and turn engine by hand to see if coolant comes out.

There is more to it. Let me suggest that one needs a copy of the Operator's Manual, and a copy of the Workshop Manual (WSM). The WSM has the circuit diagrams for the Operator Safety circuits. Part of the story is that the L3200 will shut down if it detects operator not present (seat switch)...

Automotive parts store for primary wire colors. Use a table to translate metric gauge to american wire gauge. More colors from a mail order electronic parts such as digikey, allied, mouser, etc. What matters is that the insulation is gasoline and oil resistant. If stranded wires are breaking...

Engine oil needs to be changed at least once a year, regardless of run hours. Tires checked for pressure regularly as you use it. Also don't want tractor sitting on flat tire. Grease by date, not by hours, as grease dries out.

The search can be narrowed to manageable with 1) it is a Japanese connector; 2) it goes on a motorcycle or ATV. With these search terms a few specialty vendors will be found with pictures and ID of the connectors. That's the fastest way I know. Digikey, Mouser, and Allied are good sources, but...

Another possible issue is with the mechanical regulator. If the points have gone bad, then too much current could be allowed through the field coil, indicated as a voltage rise. Not knowing if the regulator is original, it could be possible that the existing regulator has an adjustment setting...

Will a charging voltage of 18V damage my battery? Yes, it will damage it. Normal charging voltage should be about 14 VDC. I think that there is a wiring issue, which could include the ground (chassis) reference connection.

First, I'm not familiar with that particular model. However the WSM shows a harness 1 and a harness 2 - harness 2 serving the headlights. The connector from harness 1 to 2 is an eight-pin. The connector to the headlights is a three-pin, and it feeds both headlights. Maybe harness 2 is tucked...

Wouldn't start on ether or anything While ether start has no problems on some other engines, Kubotas do not tolerate it. Several instances on this forum of broken and bent engine parts when starting fluid was attempted. Good luck on your new project. Hope that you'll report your progress.

A Pro trick is to print the schematic - then use a hi-liter to mark what you've checked.

If there are any tricks to chase down the problem with the Easy Checker lights and dash gauges, I'd love to know. Fear not. Check fuses so that there is a positive supply; ground for the cluster is bright and tight; connectors in the path are not loose or pins corroded.
