Kenlowe fan

[Ashley]

After a winter break my kenlowe fan is remaining dormant.

I have checked the power supply to the fan which is OK. The return lead from the fan to the thermostatic controller is showing 12 volts on a multimeter, however if I then earth this lead the fan shows no sign of life.

Not sure how old the fan is as it was already on the car when I bought it 7 years ago, but would estimate it as "elderly". My next move was to remove the fan for further investigation, but a couple of years ago I fitted a new radiator. As I result of this I had to renew the fan to radiator attachments, and used the plastic "zip tie" attachments provided by kenlowe. I am now concerned that I could damage the radiator trying to remove these ties.

So before I go any further, has anyone got any ideas on how I might coax my fan back to life, and any advice on how best to remove the ties would be gratefully appreciated.

Firstly, put 12v directly to the fan to see if the fan itself is working or you have a wire/fuse/switch problem

Thanks for such a quick response Simon.

I think that my poor terminology has failed me when I say that the return lead is showing 12 volts.

What I have is two leads at the fan. One is a constant 12 volt power supply, the other runs from the fan to the thermostatic controller where I assume it is earthed once the temperature sense reaches the require value.

I have 12 volts at the lead that runs to the thermostatic controller, therefore I have power at the fan. I thought that earthing this lead that runs back to the controller should turn the fan, but perhaps I wrong.

Which controller are you using ? My kenlowe electronic controllers failed twice, now have revotec.

 

Wit mine the electronic controller switched a relay feed to the fan, not a switched earth.

 

As other poster said, check earth again carefully and then wire up a fused live feed to see if it is fan motor.
