fans can fail, clogged with leaves. if that the case, remove and clean them, and lube fan and benche test (removal is a pain, pull the gas tank first!!!!!)

if you do remove it, be sure to add an aluminum window screen under the cowl vents to keep debries out of the fan.

other failure can be in the switch, it can even melt do to high resistance in the wipers of the switch.

you may be able to clean up the contacts if not melted, and it wil work again, best to remove it to get at it to clean.

testing is hard as plug to fan is =hard to get at, you want to see if you are getting power ot the fan or not, then you decide if it is the switch(or wires) or if the fan needs to come out or not.

if too hard to get to plug to test, then with a sharp neddle pierce the insulation on the wires to use a probe for yoru test meter. a small pin hole wont be much of an issure on the wires as they see a dry enviroment generally.

good luck (IMG:style_emoticons/default/welder.gif) (IMG:style_emoticons/default/sawzall-smiley.gif) (IMG:style_emoticons/default/popcorn[1].gif) (IMG:style_emoticons/default/aktion035.gif) (IMG:style_emoticons/default/icon8.gif)
