New to me G1900: What... am I missing???

[rmcard]

Hi Everyone,

Just brought home said G1900, not running condition. It does look promising tho'.

It's missing several things which I hope to find/collect (i.e. Seat, screen cover below steering wheel, front headlight cover, bracketing for steering wheel assy??)

The one thing I'm not sure of that I'm missing that I have no idea what it is happens to be an electrical component of some sort that was snipped off the wiring harness located below the steering wheel behind that screened cover that's missing.

Please look at the attached picture and if anyone knows what goes there please chime in. A picture of behind the cover a properly put together tractor would be very helpful because I can't believe that the fuse block is supposed to be hanging there as well.

Perhaps you can look at the Kubota site for the parts breakdown and see if that may help.

Have you tired searching the web to see if there is a Workshop Manual available - hopefully for free?

Actually I've done both, I have the actual shop manual I bought off Ebay and I pulled up the Kubota Parts diagram from the Kubota web site.

I haven't been able to match up the wiring diagrams to the connector because I'm not seeing the wire colors in the book that I'm seeing in the picture.

Not sure if I have a dynamo or alternator either (different wiring diagrams - but look about the same). The tractor is actually at a neighbor's right now on his trailer and until I have a chance to drag it the rest of the way home and ferret it out completely I'm trying to decipher what I can from the pics I took. Oh I admit, I could probably do some more reading.

The book did come in handy showing me where the elusive bypass valve is on the belly of the hydrostatic pump which from what I've seen posted a lot of people are unable to find and believe is like a unicorn. I was able to roll the tractor around well enough to get a running start up the ramps onto the trailer... until the mower deck hanging down got caught on the lip edge of said trailer.

And the Kubota parts diagram is kinda small and not too detailed, I've got a sneaky suspicion that they might not be showing everything there.

A full on picture of an untouched tractor behind the screen would really help.

There's a few guys on here that have a G1900 should be able to help you out but I'm having trouble figuring out where your picture was taken from.
There is a thread here. http://www.orangetractortalks.com/forums/showthread.php?t=5889 it shows a schematic don't know if it's the same as yours or not worth checking though.

Pretty sure the connector that has the wires cut is hiding behind the vertical support in this picture. You can barely see it. The one that's peeking out to the right of the support is one that has it's wires intact.

Oh yeah, I do have that schematic in my book but I can't reconcile the wire colors between the picture and the diagram. I'll have to physically chase the wires out and see what goes where.

And the steering wheel is barely attached. All that orange framework in the center support is coming apart. I can shake it from side to side with some considerable movement.

My 2120 is a bit different all the wiring is on the right-hand side goes up to the switch it looks like it has met with some sabotage hard to believe anybody would cut the wires with the plug right there. I'm sure there will be others with the same model that will be able to help you out good luck!

Appears that someone's removed the voltage regulator. I could be wrong, but that's what it looks like to me. Does your engine have a dynamo or alternator? The picture is of a dynamo, pulled pic from a google search; but that's what they look like. It uses an external voltage regulator that's mounted under the dash.

Speaking of wiring....these things are known for wiring issues, so keep that in mind. If you're not up to speed on 12v electrical systems, you might want to get educated. The G1700/1800/1900 systems are pretty basic.

hmm,

Looks like I've got a dynamo. Could be it.

Would still like to see some pictures of the area under the dash, I don't see how anything would be mounted underneath there and I can't believe things like the fuse block or a regulator would be left to swing free.

Thanks!

My 2120 fuse block is just hanging.

I'll see if I can find the voltage regulator that Lugbolt is speaking off and get a pic for you, it seems our machines have a lot in common.
Think I found it just behind battery facing the side in 2120 hope this helps.

Yes, I think my missing component is a regulator. I can see that I can buy one cheap on ebay for about $32. Do I buy it now or try to determine the AC Dynamo is still working or not because there is also the option to buy both.

Took a better look at it today (still not moved it home tho') and was surprised that the serial number is very low (S/N 10091). As good as shape that its in, for sitting outside for two years, I would have guessed it was a late 90's rather than late 80's.

I'm wondering if I can still start it without a regulator as long as I have a strong battery. If I do try to start it should I prep the engine somehow because it has sat so long? First thought I had was to spray oil into the cylinders but with my luck I'll probably hydrolock it and ruin the engine.

I saw one thread where the poster was dealing with pitted cylinder walls and low compression. I could do a compression test at least. Or just start it first and see how well it runs.

Oh, forgot to mention that not only is it a low serial number, it also has fairly low hours, at about 1090 hrs.

It looks to me like the wires that have been cut go to the instrument cluster. Whatever they go to, why would anybody cut the wires when they could just un-hook the harness an inch away??

If they do go to instrument cluster you can still start the engine with a momentary switch wired to starter/battery. Pretty easy. Key switch and all gauges won't work, obviously. You'd have to kill the engine manually by using the fuel stop solenoid mechanism. Make sure you identify that BEFORE starting.

2120 is completely different. It'd need to be a G1700/1800/1900 for it to be accurate.

Mine's buried in the shed. Next time I've got it out, I'll see if I can snap a pic. But it won't be the same as yours, since I've converted mine from dynamo to Denso internally regulated alternator, off of a BX25. The white harness connectors on mine were literally crumbling apart. There is one particular connector under the radiator that gets nasty, and sometimes just falls apart (as mine did).

Be sure to grease the front axle pivot! Search for g1900 axle on this site, and see what kind of nightmare they can be if it's never greased, as mine was. Also grease the drive shaft fittings (the shaft from engine to HST). Another fun job to have to replace the u-joints and or yokes.

Beyond the common stuff..wiring, drive shaft, and front axle pivot, they are great mowers! Too bad they're still not made. If they were, they'd be $10,000+.
