Tractor runs out of gas. Bone dry.

I don't think we are working with the correct wiring diagram if all your colors are wrong.

I hot wired the ignition switch and it fired right up along with the lights. But after putting everything together the

battery has finally died. It started it once but died. It's old so I'l just go to TSC for a new one.

 

Thanks Bob!!

this may make it a bit easier - I might have one with the fuse holder shown too that I can post later

this one is a little better

Thanks for the pics Old Iron. I'll check tomorrow. I'm also saving the pics for future use! They help tremendously!!

Just be aware there are certain aspects of these drawings that are intentionally over-simplified. For example, the blue wire leading from the ignition switch S terminal to the starter relay is not a single uninterrupted piece of wire. Depending upon your particular model of tractor, there may be a single clutch safety switch in that line, a neutral safety switch and most likely a PTO switch too.

 

My bottom line when I troubleshoot is to do so by FUNCTION of the wire - not necessarily by COLOR. Color co-ordination of the harness with the manual is a great gift but if you understand the function of the wire, you got the problem half fixed.

Those are the things I just tested and all were fine! I understood the schematic! I did get the tractor to start by hot wiring it. But I do want to see where

the problem lies. Starting to look like a safety switch.

 

By the way the ignition on that schematic has the colors wrong. They're backwards along with their function. That's the switch you're

looking at. Lay the electrical connection on it and it's reversed.

 

Appreciate your schematics with the probe though!!

Wire color Schmire color

 

If diagrams are colored according to op manuals, the next person I help will say the colors are not the colors in their tractor. Another person will claim their wiring is all black. A third person has hacked wires and different colors installed by a previous owner. It never ends.

 

TROUBLESHOOT BY WIRE FUNCTION AND MARKINGS ON THE IGNITION SWITCH.

 

If you have power up to the ignition switch, and the ignition coil is proved functional by the bypass, then the defect must be in the switch, switch terminals or the wiring to the ignition coil + terminal.

[Save Old Iron 1,566]

I guess I should also ask how EXACTLY you bypassed or hot wired the ignition coil.

It was  either "B" to "I" or "B" to "S". I'd have to go double check. I just ran a jumper between the two at the ignition

switch. I had the help of another WH mechanic!!  But I still want to continue to find the problem.

[Butch 194]

Yep, based on another ignition in front of me the "B" and "I" are the same as the original

schematic on page 2 which I also have. I'll double check tomorrow.  Numbers 1 to 4 were

fine. I'll double check 5. Now this is a new ignition that I installed and nothing.

Must be "B" to "I"

 

"B" to "S" would run the starter constantly.

 

If a B to I external jumper works, then either the ignition switch is bad (you checked that)

 

or

 

the connector terminal or wire coming out of the "I" terminal are not making contact with the ignition switch.

 

I would pop the connector off the ignition switch, pop the "I: terminal out of the connector shell and give it a close look for corrosion inside the terminal or a bad crimp / corrosion where the wire attaches to the terminal.
