Xantia Cooling Fan Thermoswitch Bypass

[ecohouse1]

Surgery completed on Saturday and so far the results are positive. My main cooling fans were running all the time from start up no matter what I did so took the bull by the horns and set up a secondary thermo-switch to control their earth connection to switch them on only at the "right" temp eg 90/95 degree+ Not ideal but they were driving me nuts, Wired a variable thermo switch to the battery positive via a fuse to a 70A relay then to earth. When the temp hits the right level (probe in top Rad hose) it completes circuit in relay essentially earthing the fans to the inner wing and letting them run. As it then cools, fans cut out as earth disconnected! Cost about £25/30 to achieve and peace at last! Bit of a bodge I know as I need also to wire in a diode connector from the air con. Although I rarely (never) use it.

Might be a handy solution to anyone else with a similar problem after ruling everything else out!
