The Gator has no fuses, but Deere puts three fusible links in the system on the wires coming off the posiitve side of the starter solenoid, the same terminal the posiitve battery cable goes to. The voltage for the keyswitch has to come from these wires. Locate the fusible links and check them for continuity. They will look like fuses soldered in the wires. You can use a jumper wire to bypass and test.

the dash lights come on w/key
Customer: replied 10 months ago.
I removed the fuses and connected directly to battery and dosen't make any change

It will have a brake switch, that has to make for starter to work. It will be on the brake linkage. Look at switch and see if the brake is pushing it when you try to start?

Customer: replied 10 months ago.
there isn't a switch connected to the brake pedal, the seats don't have safety switches either. I've removed the front cover and accessed the switch.Battery is at the switch and when I jumper the starter wire it doesn't turn the engine
Expert:  Curtis B. replied 10 months ago.

You don't have to press brake for start?

Customer: replied 10 months ago.
no, this might be a little older than I though
Customer: replied 10 months ago.
I've looked for a data plate every where, is there one on these gators?
Customer: replied 10 months ago.
the voltage at the fuel pump seems low, 4.5vdc
Expert:  Curtis B. replied 10 months ago.

6X4 is not full model number. Is this TX. HS, or ???? It had a plate riveted to the frame when it was new.

Customer: replied 10 months ago.
where about on the frame would I be able to find it?
Expert:  Curtis B. replied 10 months ago.

Don't know location. Number 8 shows to be two stop switches, this is off a Worksite gator, it also has a start relay, # ***** do you find this relay? Does it have voltage to it?

Customer: replied 10 months ago.
I'll go check
Customer: replied 10 months ago.
12.5 vdc on red
Expert:  Curtis B. replied 10 months ago.

Does the relay click when you turn the key to start?

Customer: replied 10 months ago.
no clicking in run or start
Expert:  Curtis B. replied 10 months ago.

Look at the relay, it will have a schematic on the side of it. Locate the connections that relay should make, and use a jumper wire to see if it will engage the starter. You will make the connection in the relay plug in.

Customer: replied 10 months ago.
i'm guess the 2 postions on the relay marked 87 & 87A are the ones your talking about
Expert:  Curtis B. replied 10 months ago.

Not sure without having it in my hand!

Customer: replied 10 months ago.
do you know the wire colors that need to be bridged
Expert:  Curtis B. replied 10 months ago.

no. try jumper from 87 to 87a in the plug.

Customer: replied 10 months ago.
not any change, still won't crank engine
Customer: replied 10 months ago.
