Question about Husqvarna Riding Lawn Mower 42 Inch Cut Yth2042

1 Answer

Pulled the Husky out to get ready to go. Put new battery in it. Cranked for ever and would not start. determined the electric solenoid on the carburator was stuck. got it cleaned up and operating. Cranked it and it took right off for about 5 seconds. Then stopped and now won't even crank. Appears to be no power to ignition switch as I don't hear the clicking noise it makes just when you turn the key over to on postion without cranking. There is power across the battery. Noticed when the engine did start, it seemed to race up to much higher RPM than usual before it shut down. Any ideas? the mower is 42" with Kohler 15 HP engine (model YTH150). Probably about 12 years old.

    Thanks kelly, found the fuse and it was blown (actually a 15a fuse on this model). After three fuses, I finally figured out the major problem. When I took the carburator off to clean it, I took the governor lever off because I could not remove the linkage without doing so. When I put it back on the shaft I obviously did not have it in the right postion and that was allowing the engine to race. Evidently when the engine starts to race out of control, that blows the fuse. Anyway, it is running like new now. thanks again.

Hi and welcome to FixYa, I am Kelly

This statement: "Noticed when the engine did start, it seemed to race up to much higher RPM than usual before it shut down." is telling you that the fuel solenoid on the bottom of the carb lost power so it shut off the fuel.

Look on the main wiring harness of the mower about even with the foot pedals but inside the cowling. Your looking for a 20 amp fuse (Flat type with the U piece between the terminals.) For some reason that fuse has failed. There has to be a shourt some where that caused the fuse to fail. Locate the short.... start in the pedal switch area and then the seat switch area looking for shorts. After that you just have to check everything including the lights (if so equipped) for shorts. Who knows even the wiring for the fuel solenoid or the fuel solenoid itself could be shorted.
The fuse may have a black plastic rectanular cover on it but will not be far from the main harness.

If you need any assistance or have any comments feel free to respond here.

Thanks for choosing FixYa,
Kelly

How will I fix my Toyota Hino SO5C engine,when I cranked the engine,it cranks but never starts?


first thing is to run the fault codes to determine where the fault could be
it may be a simple flat battery in the fob key that is not signalling the immobilizer system or air in the fuel system if diesel or the fuel shut off solenoid not working

93 ranger will not start unless push start..put new selenoid battery is hot all lights .. horn..all works ..do I need a new starter?


To determine if you need a starter you would first do some electrical tests at the starter relay an do voltage drop testing of the starter circuit ! Without doing these test I could not say one way or another ! What solenoid did you replace ? Does yours have one on the inside of the right fender or on the starter ? Starter Voltage Drop

I have a 98 buick lesabre just got a new starter & battery put on this week and the car still wont start. Friday it cranked up 6 times and no more. Saturday it cranked 5 times and no more. what could...


Sounds like maybe bad battery cables , positive or the ground side ! You need to do a voltage drop test to see which one. Need to use volt ohm meter ! Put positive lead on the positive connection at battery , next put negative meter lead at the connection on the starter. Make sure the vehicle won't start by pulling fuel pump fuse. Have someone turn the and crank the engine , If the meter reads less then battery voltage while cranking that cable is bad and needs to be replaced. I'll also send a link for a you tube video on doing the test. Voltage Drop Testing the Starter

Sprayed down lawnmower with water, now it won't start. I decided to "wash" the lawnmower last week and now it won't start. And the really weird part is the solenoid clicks every minute...


Engine will not run with no spark or a weak spark. Continuity test will only reveal that the winding is not open, not if you are producing a weak spark that will not jump the spark plug gap.

Removing a starter from a 94 new yorker


  • Check the condition of the battery. A weak battery can't turn the starter over. Make sure the battery is at full strength before you blame the starter. Your car's instrument cluster should indicate when there is a low battery with either a warning light or ammeter.
  • Also check the battery connections, the wires going to the starter, and the starter connection. The most important wire is the big one running down the back of the battery. It is the wire that goes from the battery to the starter. All connections should be snug. Check that the insulation on the wires is intact. Tighten any connections loose enough to wiggle by hand.
  • Check the starter solenoid. The starter solenoid is a special switch that turns the starter on and off. Solenoids rarely cost more than $10, and they are fairly easy to replace. When you turn the key, have a friend listen to the solenoid for a clicking sound. If there's no sound, assume the solenoid is broken and needs to be replaced.
  • If the automotive engine is turning over and still won't start, it might be due to another problem unrelated to the starter or battery. Anything from a dirty air filter, worn spark plugs, bad spark plug wires, a worn distributor cap, insufficient fuel reaching the engine or even blown gaskets can prevent a car from starting. If you can't isolate the problem through trial and error, it may be time to take the car to a mechanic for check-up or repair.

Once you've determined that the problem is not resolved by troubleshooting the above issues, it may very well be that you need to replace the starter.

  1. Disconnect the battery cables in order to reduce the possibility of accidentally shocking yourself.

  2. Remove the electrical connections from the side of the starter. There are usually two wires: a positive and a negative wire. Remove the positive wire first, and then remove the negative wire from the starter. You may want to mark the connections with a paint pen to help you correctly reconnect the connectors to their proper terminals. To remove the connections, you'll need to use an open face wrench or socket wrench to remove the bolts.
    After both of the electrical connections are removed, you'll need to unbolt the starter from the chassis. Before you remove these bolts, take note of how the starter is oriented. You may want to mark the bolts with paint pens. There are usually only two or three bolts that attach the starter to the vehicle.
  3. Remove the starter. In preparation, look closely at your car and determine what path will be easiest for removing the starter. It might be a tight fit, but you'll need to twist and pull the starter around various engine and frame parts in order to get it out of the car. Some cars may be particularly tight, especially those with front wheel drive. You may have to remove other parts in order to get enough space the pull the starter out. If you do remove engine parts, take care to remember their proper location. Replace bolts into the same place they came from once you pull a piece off. This will help you keep up with all of the pieces.
  4. Once you've pulled the starter out, you can put the new starter in its place. You'll need to put it back in the exact same way you pulled the old starter out. Once you have it in place, put in a bolt just enough to hold the starter in place. Then connect the electrical connections beginning with the ground wire. Once the ground wire is connected, attach the rest of the wiring. Next, install the rest of the bolts holding the starter to the frame. Check to see that all bolts are tight.

Remove the smaller gauge wire from the solenoid, and put your test light on it while the ignition switch is being pushed into the "start" position. If the light turns on, the solenoid has gone bad.
