Would it be possible to tell me or even show(in a picture) me how you hooked up a manual overide switch? *What specification switch did you use? (30 amp etc..)
Thankyou! Thankyou! Thankyou! For all the information you supplier it was more than useful! The drawring wern't dodgy at all I couldn't of done better myself.
Thanks a million mate! P.S I've placed your website in my Favorites folder.
well. Thermostats open at 82C for most Toyota engines, 88C for others. I'd turn on the fan at about 90C i reckon.
You could use a Jaycar thermostat which is normally closed, and just reverse wire a DT (double throw) relay to turn it on at set temp. Perhaps the 70C thermostat attached to the thermostat housing would be suitable, as the housing probably doesn't get as hot as the water itself.. i dunno.
