where is the NSS switch located?

AS far as I can tell, the NSS has been disabled on this machine since I could just turn the key and hit the start button while standing next to the dozer.

Use of ether/starting fluid is not the best thing for any engine. JDs I have been around really don't like it and you need to be sure to use it sparingly. Has the hard starting become more of an issue as the temperature gets cooler? Hard starting can be injection pump issues, timing, cracking press...

My 450c lately has been a hard starter so I have resorted to a quick burst of ether into the air cleaner. The ether will fire off but the dozer does not always start and run. Today after trying to start it till the batteries got low, I left it and went away. Came back an hour later and with another ...

Well, the intermittent electrical nature of my dozer has become a real hassle.
Does anyone have a link or a copy of the wiring they could post?

Got a call from the starter guy and went and got the reman. Took it up to the dozer and after pulling the current old starter, installed the reman. Also discovered my hand is small enough to fit through the access hole to place and thread in that pesky bottom bolt. Hooked up the electrics, hit the s...

I did consider a GR starter and may yet go that route if the reman proves unreliable but for now I will stick with OEM.

Tried to start it the AM and the old starter was unhappy, cranking very slowly and then beginning to smoke
Enough of that, I will just have to wait till the reman is ready, hopefully next week.
Stay tuned.

So, I mounted the replacement starter on the top stud and threaded on the nut, easy peasey. Then managed to drop the lower bolt into the blackness below, oh no. At this point I decided to try the starter with just the top nut for now. It must have been at slight angle because of no lower fastener an...

Maybe I have hooked something up wrong. I will check it in the morning, something is not right.

Got the meter out and check voltages and weirdly, the start circuit reads 12.5 volts without having to push the start button!
What would that indicate? Like I said earlier, I am electrically ignorant.

First thing I did was bypass the master, no change at all

Starter is back in but I celebrated too soon.
There was no response from the solenoid or the starter when powered up.
I did not have my DMM with me so I could not check for voltage but will return when this rain shower passes.
Unfortunately, my electrical knowledge leave much to be desired.

Woohoo starter is out, was not as hard as I imagined. Raising the blade and removing the fuel filter give more room to see and swing a wrench. Not enough room to get a socket on the lower bolt and only small amount of room to use socket [at an angle ] on the top nut. Bench tested both spare starters...

Did some more troubleshooting and decided I need to pull the starter.
I have 2 spare starters so will be going in as soon as weather permits.
Finally getting some rain here after all the very hot dry days we have had all sunmmer.
