I am not 100% sure the cooling fan on my 95 KLR is working. Although the weather has been mild the fan has not come on once in the week I have been riding it. I do not have a shop or repair manual but want to test the fan circuit to ensure it is working properly. Any help would be appreciated.
Here in the Central Ca Valley summer comes fast and 100 degree temps are not too far away, I'd like to be sure my bike is prepared for the heat.
A functional check of the fan (on your model KLR650) isn't difficult; just ground the lead to the fan switch (thermal switch installed in lower right of radiator, I think).
Grounding this lead energizes the fan relay, and in turn, the fan, on a properly-functioning bike.
Doesn't work? Fan relay, fan motor, and associated connections may be suspect.
Fan STILL doesn't come on, even when the coolant temperatue needle moves into the RED zone?
Could be the fan switch itself; Service Manual
tells how to fling the fan switch into hot liquid and measure conductivity . . . switch closes with heat.
Further suggestion: Google, "KLR650 Wiring Diagram" and you'll see how the fan, fan relay, and fan thermal switch are interconnected.
DIFFERENT, pre- and post-2008 models.
