Thanks for the info. Would you have any idea what would make the water temp light come on and stay on at cold start up? It just started doing this the last two times that I used it.
Could be the ignition switch (key switch) not returning properly or the temperature sending unit (thermocoupling). The wire may be broken or pinched to ground (shorted).
Thanks Robert. I have lost my key some time back and found that one of the accessories on my swiss army knife works very well.... I just keep it in my pocket when using the tractor. I did notice that the light would go out for a fleeting moment with the engine running if I turned the switch off and on back and forth. Where is the temp sensor located so that I might do a ground check and hopefully omit one of the two options?
