SOURCE: Blown fuses when mowing

you have a wire that is shorting out somewhere, i would trace the wires from the clutch all the way back to the fuse including the relay and pto switch. You will more than likely find your problem in the control circuit between the fuse, pto switch and relay since this is what is fuse protected.

you have to start with the switch and see if its faulty
see if you can replace it temp with a toggle switch
and check the wiring back to the pto as well it mite be grounding out

Hi and welcome to FixYa, I am Kelly
The service manual is here:
http://manuals.mtdproducts.com/mtd/GetFile.do?filename=769-02100.pdf

The wiring diagram is on page 84 of the manual.

Disconnect the positive and negative terminals from the battery and make sure they do not contact the chassis to form a ground. Read for a short with the key in run and lights OFF from the positive battery terminal to chassis ground. If you ar noting a short at this time you are literally going to have to chase wires. I would start by disconnecting the red wire from the PTO switch followed bythe red wire on the PTO relay. If the short goes away I suspect a problem with the wires at the PTO clutch as this is were many wiring problem manifest due to foreign objects thrown by the belt hit the wires on the clutch. After that I disconnect the engine connector and check again. Lastly I would disconnect the dash monitor connector and test again. If you still have the problem after disconnecting the engine harness and dash monitor there is a wire chaffing some where against the chassis. You can find it... it just takes a lot of time.

On another note...
You should probably make sure the ignition switch is not causing your problem.
Key switch testing connector removed
Off = M+G+A1 (continuity) Also read each one to the case of the switch
Run W/lights = B+A1+A2 and L (continuity) Read B + A2 to to the case of the switch.
RUN = B+A1 (continuity)
Start = B+S+A1 Read S to the case of the switch. (continuity)

Don't forget to remove the large (+) wire off of the start solenoid when troubleshooting or you will read the starter winding giving you a false ground.

Troubleshooting will end up being isloation of one leg of each wire at a time. I usually make a straight line sketch of wire temination points by wire color and connection on scratch paper for each wire I test and draw a single angle line across it after I have tested it.

If you determine that the problem is in the engine alternator, I will need your engine model number so I can get the service manual for that also.

A word to the wise.... if you disconnect a wire... write down color and where it was disconnected from on scratch paper. and line it out after you re-connect it. (experience)

Thanks for choosing FixYa,
Kelly

Will it hurt to replace the 20 amp fuse in my cigarette liter to a 25 amp it keeps blowing fuses


I am wondering if the fuse blows instantly or whether it lasts a while?

Fuse ratings for cars are usually mean or average values so a 20 amp fuse needs roughly 40 amps to cause it to instantly fail. I have not heard of a cigarette lighter needing that much current so I guess there is a fault that should be located and cured before you have a fire.
Maybe it is the element that is faulty...

I think fitting a 25 amp fuse would be slightly foolish...

Why does the ATC fuse keep blowing


Fuses only blow when the current is above the limit. Tripping a 20 amp fuse is a serous current, probably caused by a shortage. Check if an animal has eaten on your cables, or perhaps a cable lost its isolation and is now connected to the plating. Use a ohm meter and try to follow the cable from the fuse to in the car, till toy see something.
