OK all you wonderful diesel guys. I need your help. Was using my 89 430 mowing. mowed 2 hours, drove it 6 blocks to fill with fuel. Started it up left for home. Saw a friend working on a 46 truck, stopped to chat. went to start the tractor nothing. It was kicking in the fuel solenoid but would not engage starter. pulled home 6 blocks and left it in the barn for 4 hours. went in and tried it and it started. Seems it won't start when warm. what the hey. any thoughts. thanks Doug
430 starting issue

Need to make sure your safety circuit is all there (nuetral, PTO's, Brake year depending). Could also be the fuze box. My fathers 430 I had an issue and once I put a meter to start reading things it made a connection. The tab that the fuze spade went into was bent too far away. I used the meter prob and bend it back and no issues since. A volt meter will tell you a lot. Check the purple safety wire at the starter to see if there is power. If not-start tracing back till you find where there is a break in power. My one 332 the connector is also a bit loose and requires a wiggle once in a while. Fathers 430 also had a bad nuetral switch when I started working on it.
Travis, went out today to check safety circuit. I don't have a purple wire at my starter. they are all red. I tried to start the tractor and it started. Just to be safe I took the wires off the started terminal and sanded them good and sprayed them with Di-Electric grease. Hopefully this was just a one time deal. It's starting now so will keep my fingers crossed. thanks for your help. Doug

What color is the wire at the nuetral safety switch and the two wire plug on the ptos ? It is a normal spade connector going to the starter (at least on my 332's, can't remember on the 430). so you could pull if off and it shouldn't turn over to start.
Travis, checked the wire on my safety switch. there is about 3" purple wire that is spliced to a red. So I know which is the safety circuit. The splice may be the problem. I will repair that and if it still is an issue I know which wire to disconnect off the safety switch to see if it will start. thanks Doug

Ya, that red wire is bypassing a non-working safety switch I am guessing. The hack job may have damaged the wires so make sure power still makes it through (continuity test).
Doug, the safety switch system on the 332 (and I assume the 430 as well) interrupts power to the starter solenoid when one or more of the the switches is activated. When in a no-start, pull off the hot lead to the solenoid, if you have 12V when you turn the key,the problem is not the safety switch system, but a dead solenoid. I had a long-time problem with no-start when hot on my 332 and the starter solenoid was the problem. BTW, if it is the solenoid, you can get a much less expensive aftermarket solenoid.

or get a 330 kill button if you don't like the solenoid cost
ran the machine for 2.5 hours mowing and collecting. shut it off several times (as a test) and it started right up every time. I think the sloppy splice was my problem. thanks Travis,bill and knottyrope for your help and suggestions. I love this site!!!!! Doug
