Question about Craftsman 17.5 hp 42 in. Deck Lawn Tractor - CA Model

8 Answers

I have a Craftsmans riding mower with a Kohler pro 17 HP OHV Model # CV490S Spec# 27508 OEM Prod# 177745... A friend was over and hooked up the battery backwards, it sparked and alittle smoke came out from under the seat area. It 15Amp fuse started melting. I replaced the fuse and hooked the battery up correctly, However nothing happened not a click or anything. I replaced the solenoid and the switch to start the mower and tried to check the wiring the best I could. Now it still will not start or even make a click. I can jump the solenoid and it will crank but not run... What do I do???

    I went through it with a omh meter and all wires reads good. I have recharged the battery and within a few minutes of trying to crank it the battery is pretty much drained. What do I need to do to get it to spark? I have had 3 back surgeries and my wife 1. We have 3 kids and I am the only one able to work now and I can push mow just over an acre and dont have the money to go to have it fixed or get a new one.

  • Cronberger Mar 14, 2011

    I thought about rewiring it but a wiring diagram would be great or even a manual as I bought this mower used.

  • Cronberger Mar 14, 2011

    sorry that was I cant push mow with my back.

  • Cronberger Mar 14, 2011

    where can I or does anyone have a wiring diagram or manual fot this Craftsman Kohler Pro 17 HP OHV

  • Cronberger Mar 14, 2011

    There is no melted wires

  • Cronberger Mar 14, 2011

    There is no melted wires. I went through with a omh meter and all wires have a great reading. It will crank if you jump the solenoid put will not run.

  • Cronberger Mar 14, 2011

    ok so the battery is in the back and the pos post is on the right and the neg is on the left if you are standing behind the mower. the smoke came from the left side of the mower. so if they are melted would a omh meter still detected it being full wirer without any breaks or melt down?

  • Cronberger Mar 14, 2011

    could the smoke have came from the fuse the comes from the pos post to a little fuse box that has a 15 amp fuse in it that has the 2 prongs. The pplastic on that fuse melted but did not blow.

  • Cronberger Mar 14, 2011

    being that it is firing but not running would that still be the case or someone keeps telling me that it might be the spark plug or the igintion module.

  • Cronberger Mar 14, 2011

    being that it is firing but not running would that still be the case or someone keeps telling me that it might be the spark plug or the igintion module. if the wiring or fuse are messed up would the motor still turn over when jumping the solenoid?

  • Cronberger Mar 15, 2011

    not sure what you mean voltage going to the ?? from the ignition switch.

  • Cronberger Mar 15, 2011

    Im not sure what you mean by magneto from the ignition switch.

  • Cronberger Mar 15, 2011

    Even with me jumping the solenoid and trying to start it like that the battery was drained within a few mins and I had the gas on and the trodle all the way up on choke and I never smelled any gas and there is gas in the tank. What can that mean. Do you think that might have anything to do with it?

  • Cronberger Mar 16, 2011

    I have thought about rewiring it but I do need a diagram because I want to make sure everything is right and even all colors are correct.

  • Cronberger Mar 16, 2011

    Thank you Heatman. I have replaced the switch. but yea but do you know if the purple wire is to be grounded or hot?? I really need a wiring diagram.

  • Cronberger Mar 17, 2011

    hey im the wife now lol he told me to write you and tell you that it is a 5 prong switch.

  • Cronberger Mar 17, 2011

    the crazy thing is that I bought the mower used. It has a john deere body craftsman kohler cv490s engine and a scotts deck. So with that what number can i try to find for you!!!!??? Hey and thank you so much for helping us. You are great !!

  • Cronberger Mar 17, 2011

    ok well the purple is grounded wow

  • Cronberger Mar 17, 2011

    ok Here are all the numbers that I could find. On the John Deere body I found GXSABAJ010984 MODEL # 15.538 GEAR022797A then a bar code that looks like for when you purchase it 7 59936 10067 3



    On the Motor I found: KOHLER FAMILY 3KHXS.4902GB DISPL (cc) 490 MODEL# CV490S SPEC# 27508 SERIAL# 3324615611 OEM PROD# 177745 and a circle with a check in it that has N11236 beside it.



    Oh man I really hopes this help you. My husband has a very short temper and gave up, and now I am trying to do it. I am the one that has got to mow the glass. He is only here a few nights a week as he is a truck driver. If I had the money I honestly would just take it somewheres. Oh and by the way i'm not afraid to get my hands dirty. I change my own oil in the cars!!! Thank you so much, Tina

  • Cronberger Mar 17, 2011

    Hey was you able to get that wiring manual?

Hi,

according to your problem first make sure the battery is OK and check the wires are connected properly. Check the engine. You can rotate the engine governor shaft clockwise and tighten the governor lever. You can contact your nearest technician.

Hi,
After eading through everything that you have tried... it occurs to me that you have not mentioned the ignition switch...
I believe from what I have saw so far theat you may have fried the switch...check to see if you have power 12dc to the switch....then also check to see if you are getting power out to the starter soleniod...
I am also thinking that the bad switch could be the source of the battery drain...
You could check that by marking all of the wires going to the switch and then disconnecting them...
Just a few things that I can think of off hand that may help you...if I think of more I will post...

    Okay,

    Not sure about the purple wire ....but...

    I did find this wiring diagram that looks like it would be the same or similar to your tractor....



    http://media.fotki.com/1_p,swwwfdftgdtgq...



    You also can get a wiring harnes for the motor from sears here but I'm not sure that it is a complete tractor harnes...I think it is only the motor...



    http://www.searspartsdirect.com/partsdir...=



    You will notice the tractor model number at the top of the wiring diagram... search the sears parts direct site with that number for a complete tractor wiring harness or even a wiring diagram...if you can find your exact tractor number...


  • D. Floyd Kolb

    Okay with a 5 pole switch you should the purple wire I think should be hot when the switch is on....the only ground wire would be the wire going to the frame and that is normally green...but not always...

  • D. Floyd Kolb
    D. Floyd Kolb Mar 17, 2011

    Sorry, went to bed and missed your last comment till this morning...
    If the purple is grounded then I would trace that wire and see what is going on there... and what it is grounded too... I think that is your problem....
    Do you have a John Deere tractor number...(model) maybe we can track it down that way...

    See where the purple wire goes and then unhook it at different spots till you figure out what is grounding out on it...

I know your friend feels bad...using a digital meter you need to follow, from the positive post (disconnected from the battery), the path for continuity-do it in sections, there may be a fusible link burned out past the fuse that burned out. Spend extra time on wiring near the blown fuse as it sounds like on may have burned up internally but the insulation may still be intact.

Posted on Mar 15, 2011

  • mike mountain Mar 15, 2011

    it will crank with the key now? If so, you may just need a battery to get it running-you checked all the wiring with an ohm meter, and found no breaks, then it has to be alright if it has enough cranking speed to get it going-you can jump the battery, just don't overdo it with a spinning starter or you'll be replacing it too-no more than 10 seconds at a time, and give it 30 seconds off before trying it again.

Hi, whenever a supply, battery etc, is hooked up in reverse usually we must expect catastrophic destruction of almost ALL the sensitive, and polarity conscious components.

Often there is Polarity protection, usually by way of a Diode, this may, stop damage, but usually the Diode is not "Fast" enough to prevent damage, and also usually ends in the destruction of this diode, in any event, it will usually go "Open" circuit.

"Letting the smoke out" as we engineers say, is never a good thing, and is also usually the "Tip" of the iceberg so to speak, as if this happens then usually "Other" damage will have been caused too, but not to such a destructive level.

Whenever this type of event happens, the entire board should be suspect, and NOT repaired, unless complete semiconductor & discretes are replaced in totality, and this usually isn't an option, In these cases we usually replace the entire board with a NEW known good unit. As even if successfully repaired, no doubt the board would have been so stressed by the polarity reversal that "Other" components would simply "Fail" over subsequent time.

What to do... Replace that board, and hope that there isn't any Co-lateral damage elsewhere.

Also get a service manual.

The fact the battery drains suggests there is a problem somewhere in the wiring. recheck all the fuses for continuity (not just a visual inspection) and i would suggest replacing any relays you can find in the fuse box. when you hook up the battery if there is a relay burned out that is stuck on you just need to feel the top of it to find the culprit as it will be very hot.

I am providing you with the service manual for the motor and shortly i should have the service manual that will include the wiring. there is a fuel shut off relay on the carb and you may want to check that as well.

In the wiring there will be a fuse link, or a protect diode, and the protect diode is probably the part that went bad. It probably is wrap up with electical tape. I would start unwraping the tae, start by the ingintion switch and make sur it is stlill working correctly.

    You need to check and see if you are getting any voltage going to the magneto from the ignition switch.

The electronic ignition module and a part of the wiring harness was fried - you will have to replace the module and replace or rewire the harness.
The ignition module can be found here
http://www.bestsmallengines.com/pages/parts/viewbybrand/8/KohlerEngine.aspx
no direct link - you will have to navigate to your engine CV490, then to Ignition /Electrical section, it's part 21.
I couldn't find an entire wiring harness online - you will have to replace every melted wire yourself.

  • Azrael SRL Mar 14, 2011

    That smoke came from a melted wire - even if you can't see the damage it doesn't mean that it didn't happened. Locate the damaged wires and replace them.

  • Azrael SRL Mar 14, 2011

    Yes, the smoke could have came from there but if the case melted then the insulation on those wires has been even more damaged. Jumping the solenoid powers just the starter, directly - it will turn and that is all. The ignition module is still dead so the motor will still not run.

You'll need a meter and you'll have to go through the wiring from one end to the other to find out what fried. The fuse only protects the wiring to a point. It could have burnt out the switch or a contact etc. Only way to tell is to check the wiring from one end through the other to find out where. The start switch would be one good place to start looking. Obviously it isn't getting spark if it cranks but will not run.

    I'm trying to find you a diagram... so far haven't located one. However here is a free manual for the engine I think.. you can download http://www.asberry.net/files/TP-2339-D.p... Perhaps there's something in there that will help you with spark to the plug.

  • mszona Mar 15, 2011

    Check the battery to make sure it didn't screw the plates when it was hooked up backwards. See if it will work on something else. Also the ignition system has a kill switch. That could have shorted out when the battery was hooked up wrong. Check out the troubleshooting guide in the manual I gave you the link for last post. It has some diagrams and pictures to follow.

Can you give me a ballpark figure on replacing a head gasket on a older Craftsman riding lawn mower...


there are many variables, since you didn't give any specifics. if it is an older, single cylinder, L-head engine, labor would be roughly 1/2 hour; if an older twin, L-head, about 1 hour; if it's a kohler, add about 1/2 hour; if it's a single, OHV, about 1 hour; if a twin OHV, 1 1/2 hours; if a kohler, add 1/2 hour. each shop has it's own labor rate. flat rate manuals will vary and are not realistic when dealing with old, possibly rusted or frozen bolts, which will increase the cost of repair. a new head gasket will usually cost between $5 to $30, depending on which engine you have. {some older craftsmans had a briggs laid sideways or an onan. these will require a lot more work and the labor would be higher]
