Stab in the dark at Black for ground, plus yellow/black
I don't have a manual for it, an 1860 may be similar, http://www.kubotabooks.com/AutoInde...Owners Manuals/&file=BX1860 BX2360 BX2660.pdf
but best if you can get the correct one if it's available. Send North Idaho Wolfman a private message and see if hes has one squirreled away.
check ground on sending unit is good put 12v to power wire gauge moved to 1/2 tank. 12v to power wire again gauge went to 3/4 12v again gauge reads full. (tank is full) will see what what it does when fuel goes down again thanks
UMMMMM.... I'll bet you've either fried the sending unit or the gauge.
The sending unit does NOT get 12V ever, it is a variable of ground not positve voltage.
My bet is your gauge is going o be on full all the time.
Thank goodness your dealing with diesel (very high flash point)...if it was gasoline you might be pushing up daises!
when i first check voltage iam thinking i had 9 volts when gauge was reading empty now with it reading full voltage is 0.278 per your last post iam glad it diesel too
