Hey, I just bought a 112 John Deere. I would like to restore it; however, there is no serial number on the tractor anywhere. I cross referenced the Kohler motor and figured out it is around 1970. It did not come with a battery. I'm sure someone knows, what kind of battery does it take? I want to see if it will even start. Thank you

I was mowing and the tractor lost power and died.
I noticed I did not hear the fuel pump running.
I pulled the fuses in the tower, found no issues so I put them back.
Fuel pump started working again...

Now today I go to start and pump is not working.
I pulled the deck pan.
There are three wires going to the fuel pump.
Red
Black
Black/White.

Red and Black I have 12 volts.
I am assuming Black/White is for the fuel gauge?

My fuel gauge is also pegged at full today. Never seen that before.


Can someone confirm the wire colors?
Any last checks before I buy a fuel pump?

I printed out the manual pages and got my meter out.

I have good power and good ground up to the connector for the fuel pump.

I checked the actual ground and power on the actual fuel pump - removed from the tank.
I lost the ground on the fuel pump.

I jumped a ground from the frame to the pump and it works fine.

I checked resistance from the external fuel pump connector to the fuel pump itself, nothing.

There must be a break in the ground connection between the metal plate of the fuel pump.
This is a sealed epoxy piece...

With it all back together, if I jump from the frame to the metal top of the pump it works...

So I guess I need a new pump due to the internal wiring?
