L3710 HST Weird starting issue

[DavidS]

This morning I started up my tractor as usual with no issues. I was bringing firewood up to the house. I shut the tractor off while I load the bucket. On about the 3rd start there was a funny click / snap sound and the starter never cranked. I played with the range shift lever to confirm that I had it in neutral and it was. I tried to start it again and there was no dash lights at all so I checked the voltage in the battery and there was 13 volts. I then pulled all the fuses by the brake pedal to see if any one was blown and they were all fine. Then just for haha's I turned the key. All the dash lights were back & it started right up. Then I finished with the firewood and started and stopped it several more times with no issues. I am concerned that this issues is a symptom of something getting ready to fail which will become a major issue as I use the tractor to plow my 700' driveway.
Has anyone had this issue? Does anyone have an idea what could have caused this issue?
Thanks
David

Seat switch going out alignment a bit?

I would also bump the PTO selector or check the switch alignment on that.

And the HST switch could bet the problem - this sounds more likely than the other 2 mentioned.

I had a similar situation on my BIL B2920 ..... no start - somehow when getting off the PTO level was bumped a bit and once moved it cranked fine.

The "no dash lights' condition pretty much rules out safety switches and related circuits. It smacks of battery, battery cable/ground/power connection somewhere. I would revisit that side of things. Where the ground cable bolts to the tractor would be a good starting point.

The “snap” could be a short to ground . Don’t overlook the wiring insulation along with tight connections. Any damage to the insulation can allow the electrons to take a shortcut.

It sounds like you have a loose or corroded connection. Check all cable ends and grounds. Make sure they are clean and tight.

Corroded fuse. when pulled and put back in, it remade connection.
