Might Need To Hot-wire My Kubota

It appears the OP has a voltage issue if he can find just .98V on a circuit requiring a 6 volt test; it would certainly be worth determining whether the solenoid is at fault given the cost of replacement

okay- if starter turns, but solenoid not working, you already confirmed the issue. your solenoid is bad or sticking. find out if you can get a replacement solenoid, if not, I'd try the local autostores for a compatible solenoid for it otherewise you would need to pony up cash for whole starter/solenoid.

I cannot test the solenoid because I cannot apply 6 volts to it yet. Will try tonight with my 6/12 charger.
The only thing I have tested is starter spin and that works great.

Right, why mess with the starter if you have very little voltage? Start at the 1st part of the circuit work your way to the end (starter). Like I said before don't overlook that ground wire.

I think just to be safe I'll unbolt, clean, and reassemble all my ground connections while it's still summer here in Colorado.

Can an IC Regulator cause such voltage loss to the starting circuit?

Does anyone know the voltage sent to the starters Black/White and White wire at crank?

For the life of me, I can't see why someone would use a 6 volt solenoid in a 12 volt system. By looking at your wiring I don't see anything that drops to 6 volts. .98 volts isn't none to me, that could just be bleeding thru. Make sure you have 12 volts coming out your key switch.

I feel ya, Lee. I can understand a dual voltage fuel solenoid. I can't wrap my mind around a 6v starter. Although, the old JD 4020's had 24 vdc start on 12vdc system. Sounds like he may have multiple problems.

I agree here.

Sorry. WSM as in Work Shop Manual. BW as in black and white.

Here is the schematic I have been referencing.

Not sure where its breaking down to 6v???
If you follow 12R up thru the 30a Slo-blo it T's into another wire, going right into a set of fuses, and left(on the schematic) to another T down to the MAIN SWITCH. Do you have 12v at the MAIN SWITCH when checked from term. 30 at the MAIN SWITCH to batt-??? THen check from 30 to starter solenoid -. Do you also have power from term 50 at MAIN SWITCH to batt - and starter solenoid - with the keyswitch being held in the crank position?
ALSO, pull term 19 from MAIN SWITCH to deactivate the glowplugs... A faulty glowplug will kill a battery in a hurry...

The schematic tells all. Providing you have power to the keyswitch, the circuit you need to trace goes from the keyswitch, through the two safety switches, to starter(terminal S). This wire will be energized when you turn the key to crank the engine. The "no power" wire will energize, after you supply power to S and close the switch via the solenoid. I would assume the safety switches to be seat and neutral (maybe PTO). Your wire 12 is just your battery voltage out to the tractor. It supplies voltage to your keyswitch thru the 30a fuse. I suspect you'll find a faulty switch or connector. Happy hunting.

Kevin where do you live at in Mo.?
