30 amp fuse blows when trying to start engine

I have checked for shorts and can not find any. I put a new 30 amp fuse in and after several rotations on the engine the fuse blows. Could the armature be causing this?

I always start by unplugging lights, kill wire to coil electric clutch if it has one ,sometime its the fuel shut off solenoid on the bottom of carb if it has one.
You can keep trying until you find the thing that does not blow a fuse or use an ohm meter to read from pos cable to ground of tractor unhook ground wire to battery you will read short to ground thru coil kill wire,starter solenoid small wire on spade,fuel shut off
solenoid ,electric clutch ,rectifier (charging system )and large wire to starter thats why I unplug them .
I have seen more shorts from lights , fuel shut off solenoid , charging system. not ing coil not safety switches not even bad starters.
good luck

John Deere Tractor...If you put a battery with more cranking amps than what's called for will it blow fuses? When we start the mower it continues to blow fuses. This was after the battery change.


NO
a battery with a higher crank specification only means that you can spin the engine for longer before the battery goes flat
blowing fuses is from a dead short in the wiring, battery connect up wrong, problem relays
basically the positive of the battery is through the fuse) connected directly to ground at some point

I have a newer craftsman riding mower, its a 24 horse, 42 inch cut. When I was mowing today, the deck cut off then the mower died. Upon inspection, I discovered a blown fuse (20 amp), I replaced it and it...


By uping the fuse rating you are definitely putting your equipment at risk for damage. The 20 amp fuse is doing it's job. what you need to do is find the reason it's blowing. Stop running you newer machine with the 30 amp fuse and look for the high current source. Hopefully you know what the fuse is protecting and start looking there. A fuse blows due to a high current condition. If it's a motor it could be a mechanical binding of some sort. If it's wiring, it could be caused by a loose connection or exposed wire shorting itself to ground. Look for signs of obvious damage first but if you can't figure out what it is you should have it checked out by a profesional before you cause more, damage and expense.

Cub Cadet 1861 amp light comes on when the PTO is engaged and after mowing for a short time the PTO disengages and now the 30 amp fuse blows and stops the engine


Sounds like you have a short circuit, either in the PTO clutch, or in the wiring that goes to it. Inspect the wiring for any obvious spots where insulation has rubbed off or burned. Also look at the wiring at the back of the PTO engagement switch for these signs. Before buying an expensive PTO clutch, unplug its connector. Drive around with the PTO switch on (even though the PTO won't activate and the blades won't be engaged). If the fuse doesn't blow, the problem must be within the PTO clutch. If the fuse still blows, it must be in the PTO switch or the wiring from there to the clutch. Use an ohmmeter to trace and find the short. Good luck!

Craftsman garden tractor Mod # 917.257740 blows main fuse.


Try checking the battery - make sure it is not under rated - over rated and be sure the starter it's self isn't drawing too much amperage.
the battery may need replacing and for a temp fix - put in a larger fuse - say 50 amp.
Thanks for choosing FIX Ya

Starts and runs good but after an hour of cutting when you turn off.. then you want to cut again it will start just fine but when you engage the blades the fuse blows it has a 20 amp fuse is this the right...


I normally see 30 amp fuses to the deck...but it depends on which mower you have. If you place a larger fuse and it does take a 20 amp..you may burn something up. I would check the blades, spindle towers and clean all the stuff on top and inside the deck to look for something catching on the blades. www.nnyparts.com

try looking for a broken wire or a wireing harness shorted to ground, the fuse blowing in the harness will lead you to it if you are able to see where the wire goes. you have a short somewhere may be the fuel pump, too

Riding tractor blowing fuse


Put a volt meter on the battery when running. Shouldn't be higher than 14.5 or so. if so, it's overcharging. If you checked for shorts, did you run a continuity (ohm) test with a meter to see if the fuse is going to ground in anyway....do this. Disconnect battery completely, ground cable first. With fuse removed check each direction of fuse wires. If getting an indication of going to ground, unplug ignition switch. still grounding? check starter solenoid with ohm meter for grounding. With wires disconnected, check between battery side of solenoid and body of solenoid where it mounts, or a good chassis ground. (you might check that the solenoid mount is grounding to the chassis first) Then between the starter side. And the small connector from the ignition switch. It should not be going to ground at all. The ignition switch sends the ignition to ground to stop the engine, and the safety switches go to ground to prevent starting when in improper position. One of these switches could be faulty as they also allow voltage for ignition through when in proper position. Check switches. If two blade, it should open or close when operated. If 4 blade, one side is open, the other is closed when operated. With ohm or continuity meter, connect to two blades on 4 blade switch and see if they connect. Push button and see if there's a change. Try the other two blades. You should see a change on both, but different. Again, two of the blades (connectors) will see each other, two will not when button pushed. Same on two blade switch. Either open (see each other) or closed when button depressed. If not, bad switch. Some of these riders came with a 30 amp fuse, by the way..... 4x4papa
