8 HP 4-SPEED

[CHARGER9AUTO 3]

I have trouble with my '73 8 4 SPEED with Kohler K-181S it does not start all the wires look Good except for one Green wire runs to the Solenoid I need put another electrical Connector so it's fixed . I Charged the battery if I take the Cables off nothing happends . Ben :omg:

if you mean by it doesn't start, that the starter isn't turning, it is eighter a bad starter, solenoid, or ingnition switch. With the ignition in the off position,the tractor in neutral, try jumping across the two big terminals. If the starter engages and turns over the engine, then you have a bad solenoid or ign. sw. problem, that could be a loose wire. If the starter doesn't turn over,and you get a big electrical arc when you try to jump the large terminals, then your starter is jammed. The 73 4 speed starter has a permanant magnet stator, it rust very easy and with little clearance between the stator and rotor, the build up of rust jams the rotor. If the starter is jammed you may be able to remove it and turn it by hand. On my old 73 I use to take out one of the long bolts that hold the starter together and squirt some wd 40 into the hole and then replace the bolt. I found over time that the wd 40 desolved the adhesive that held the magnetic stator in place and the stator fell apart. I gave the tractor to my Brother,and we found a used starter ,and replaced it. A used unit was about $ 30.00 a new unit is over $100.00.

If you know how to use a volt meter, you can check your electrical system in about 5minutes. First check you battery voltage, you should have about 12.5 volts, with out the tractor engine running. Next check it again with the engine running ,it should be 13-14 volts if yourcharging system is working, if not check the connection on your voltage regulator. Next remove the starter wire from the solenoid, and check the voltage on the starter side of the solenoid, when the key is turned to start, it should read around 12volts . If it does then your solenoid, battery and ignition switch in the start position are ok and your starter is bad.

Next remove the spark plug wire, turn the ign. sw. to run, check the voltage from the battery ground to the + side of your ign. coil, you should have 12volts minimum. if not you may have to change your ign. switch. If you have 12volt, then test form the + side of the coil with onel ead of your tester and the other lead on the - side of the coil as you manually turn over the engine, when the ign. points close you should get 12 volts. This test will confirm in the run position voltage is getting to the coil. The points must be gapped propertly on the 181S as the gap also affects the timing. If the engine backfires and runs rough when hot your points are pitted, and need to be dressed or replaced.

Hope this helps you get it started. Good luck Joe in Norton

Joe, I need to check into the problem with 8 HP 4-Speed I keep you updated . Ben :omg:
