| HET replaces the complete CDI system for TRA-12D and S14D Engines |
| OS69 Ignition Module replaces the YJ69 used on TRA-12D and S14D engines |
| Originally the ignition system turned the engine on and off using the same key switch used to start the tractor. As the key switch aged, it often became faulty in that it would send a 12V pulse to the module, which would ultimately destroy it. To avoid buying another replacement module, it is highly recommended that a separate switch be employed. Reference the wiring diagram below, and you will notice that the new switch should be connected between the white lead of the stator or yellow lead of the module and any convenient ground. If the white/yellow lead is brought to ground, the engine will die. If the white/yellow connection is open, the engine will be allowed to run. Installing a separate switch in this fashion will ensure that the module will not be subjected to stray voltage from the battery. |
