 Jinma 284 Ammeter 30 Amp fuse keeps blowing

Hi. Can anyone help me with this? I ran my 284 for an hour or so today clearing for a garden. I shut it off, then when I tried to start it again a few minutes later there was no power to the instument cluster and no start. The Ammeter 30 amp fuse was blown.
I looked for bad wires and inspected the key start and gauges. When I put it all back together I could put a new fuse in without it blowing and the tractor started, but when I turned it off I couldn't start it again, the same fuse was blown. If I try to insert a fresh fuse it blows as I out it in. Any ideas?

A bad keyswitch is not out of the question, but a short in the glow plug circuit should be ruled out first. Remove the green wire from the glow plug buss bar, tape the exposed end so it can't touch metal, replace the 30A fuse, then see if your fuse problem goes away.

Your engine should have 3 glow plugs sticking up just below the valve cover on the left side of the engine (as viewed from the operator seat). They look sorta like skinny spark plugs. They're tied together electrically by either a one-piece copper strip or a series of wires string from plug to plug. The end near the fuel tank should be fastened to a green wire. That's where you disconnect to take the glow plugs out of the electrical system

Thanks, again! I'll let you know how it goes. It will be later today, probably, before I get back to it, since I have to go into town and get more fuses.

Thanks again, Greg. I removed the green wire from the copper strip as you described and the fuse still blew when inserted. Does that mean the short is in the key switch?

Sounds like it. The OE keyswitches have a long and documented history of problems like this. I recommend a Ford or Lucas cold start switch to replace the OE switch. "Cold Start" is the operative phrase. There are Ford and Lucas switches for both gasoline and diesel tractors. You want the cold start type for your diesel.

1. Can you tell me where I can obtain the switch?
2. Is there a way to run the tractor without a switch in the meantime?

Do an internet search for "tractor cold start switch", there are hundreds of places to buy them. Your area farm supply store may even have one hanging on a peg. In my experience, the current Ford type switches are now too being made in China. They're still better than the OE switch in your Jinma, but still not as good as the Lucas switches - if you can find one (they're hard to come by).

And yes, you can run the tractor w/o the keyswitch. Just jump the starter at the solenoid terminals. That too has been discussed literally hundreds of times. Make sure the transmission is in neutral first though. But understand - that as long as the 30A fuse remains blown - you won't have lights or instruments.

Also note that your battery will not be charging while the tractor is running without electrics. You may want to put a charger on it every few times you start it just to be sure you don't strand yourself out in the fields.
