no1 Posted February 7, 2008 Report Share Posted February 7, 2008 What black box did you replace was it the one on the fan cowl (rectifier) it wont be that one it is the one under the bottom yolk on the frame (regulator) the fan has a constant live to it all the time the thermo sender gives an earth Quote Link to comment Share on other sites More sharing options...
tombo46 Posted February 7, 2008 Report Share Posted February 7, 2008 I recently had a problem with my regulator and had to replace it. replaced the thermostat too, when the wires were crossed the fan ran fine but it wouldnt start up. in the end i went down the garden and gave the motor some hammer until either the fan kicked it or the coolant boiled over. Luckily the fan kicked in but it had to get bloody hot!! does it work if you just bypass the thermostat? Tom Quote Link to comment Share on other sites More sharing options...
