I have a 02 Honda Foreman S 4x4. I lent it out and it was returned with problems. I need help. Problem #1 the head lights do not come on. The display lights for the speedometer work just not the head lights. Problem #2 the oil cooling fan turns on instantly when the key is turned on and does not shut off. Problem #3 the 4x4 light is flashing 4 times. Problem #4 the battery is dead.

Does any one know what the flashing 4x4 light, 4 times indicates or where I can find indicator codes? And how to test the thermo sensor or troubleshoot the cooling fan? Could these problems be related to the battery???
