fuel gauge reads backwards anyone know what color wires are to fuel gauge thanks

Stab in the dark at Black for ground, plus yellow/black
I don't have a manual for it, an 1860 may be similar,

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.

thanks 100td i can fill tank up and gauge reads empty when tank is almost empty gauge reads 1/4 ?

 

[North Idaho Wolfman]

Yes sounds like a bad ground connection to the sending unit.

And + Fuel gauge wire is Yellow/Blue.

 

[stumpcutter]

thanks will check sending unit wires

+ Fuel gauge wire is Yellow/Blue.

Correct per 1860, no idea where I got Yellow/Black from, must be some bad sectors on the hard disk, good thing it was a stab in the dark!

Must be some bad sectors on the hard disk!

I have that problem too!

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

Take the signal wire Yellow/blue off of the sending unit and measure OHMS on the terminal of the sending unit to ground.

 

[stumpcutter]

with gauge plug unhooked probing signal wire back to sending unit i get 11.1 ohms

 

[stumpcutter]

ohms on gauge are 18.6
