1863 Cub Cadet issue

[RobertIHCubCadet]

My 1863 has been a fantastic tractor not fond of the plastic skin but with everything else this has been just a great running tractor for my Grandfather and now myself for years. Now I'm having an issue. Started it up 2 days ago, it was running strong on start up then all it once completely shuts off. Went to start nothing at all. My 20amp fuse blew-replaced. Tractor starts but shuts off in 5 seconds. I started with bypassing my seat switches-no change. I found out it would stay running on low rpms with choke on. Checked my fuel lines and flow-Good. Still at full throttle stops in 5 seconds or less. I pulled air cleaner base off ran a wire from battery to red wire fuel solenoid-starts up and runs great at full throttle with no issue-Im not much of an electrical guy that's where my electrical diagnostic ability pretty much stops. The only thing I can add is the last time I was mowing I noticed my amp gauge had lit for a period of time. I sure would appreciate some experienced advice here. I do plan on starting the process of looking and checking my wire connections.

Good place to start. Go to the tractor engine connector and then the corresponding terminal on the ignition and see if you have juice with the key on.

I don't see your charge light on or the blown fuse as part of the problem.

You didn't ask but that plastic front end will likely outlast you if you don't ram the tractor in to something. It's actually really tough stuff. Just not a bulldozer blade tough.

Thank you Mike. Just starting on that now. I have put a guard on the front although I've never rammed anything- best to be safe. I've just noticed it to be a bit brittle with age. I just wasn't sure what to-do with testing things or if a voltage regulator issue could cause all this or a drop in voltage etc. But definitely going to continue with the basics here.

I've seen heat damage to the hard shell and terminals on the ignition switch.

The only blown fuses cause I've seen is the headlight harness grounding somewhere.

You probably have a wiring problem for the fuel solenoid. It ran fine when you bypassed the wiring and ran one straight from the battery to the solenoid. See if you have power for the solenoid wire coming from the chassis at the connector at the motor. It's a red/white wire. If you don't get power with key on, then your problem is between that connector and the ignition. If you do get power then it may be problem between the motor connector and fuel solenoid (red wire)

Had that problem with my 1863, turned out to be the 12V lead and connector to the ignition switch.
