Customer Question

I have a John Deere 330 diesel garden tractor. When I turn on the ignition to start the engine pre-heater the light on the dash comes on normally and then goes out. After the engine starts the light comes back on and stays on. Can you give me a clue to what is causing this.
JA: Sometimes things that you think will be really complicated end up being easy to fix. The heavy equipment mechanic I'm going to connect you with knows all the tricks and shortcuts. Anything else you want the agriculture mechanic to know before I connect you?
