  • Electrical question
  • My apologies if this is too off the subject of this forum, but you all have answered many questions re my NAA so I thought I'd try. I have a Kohler engine (Craftsman lawn tractor) that will not turn over at all, no sound or anything. Jiggling the wire from Ignition switch to the solenoid? SOMETIMES makes it go something like a grunt. Is there a way to test the solenoid or ignition without replacing them first? The battery is brand new and tests at 12.68 volts and the starter is new.

  • It turned out to be several bad connections. The person who gave the tractor to me because it was "no good" always left it outside and several of the modules were caked with mud. Don't know exactly which one it was because I cleaned them all before I tried to start it. Probably more than one module contributed to the problem. Thanks again for all the suggestions.

  • It is a fuse.
    Open the hood on the right next to the battery there is a spade type fuse holder.
    The fuse is probably not blown, but the connection goes bad. Pull fuse and clean and or replace. Also clean contacts in holder.

  • The Solenoid can also be bad, but I would check the fuse first.
    If not the fuse, you can run a jumper wire from the battery to the solenoid and see if that works. If that does not work jump directly to starter from the battery. If that spins starter then it is probably the solenoid which is relatively cheap. You should also jump the lockout connections at the seat and at the blade engage linkage to make sure they are not bad.
    You can also check continuity of the seat and blade lockouts with an ohm meter.

  • Most riding mowers and units built today have an OSAH mandated built-in safety kill switch so if/when you climb out of the seat, the engine will die. Your issue seems to be the same as many riding mowers I've worked on and it turned out to be the kill switch and wiring under the seat.
