I had posted a few weeks ago about the main radiator cooling fans going nuts and coming on randomly
First when the engine is started from cold then sometimes not. Mostly the pattern was "come on with cold engine then switch off when temp guage reaches around 60 and stay off". Fans come on a few seconds after turning key to glow plug stage, first one fan slow then two fans fast. Just this morning on my 20 mile commute they come on full speed all the time even though the guage is normal. I am assuming that the wires from the brown thermistor sensor have now gone completely open circuit. I see the two wires coming from the thermistor plug disappear into a main loom which then loops off towards the fuse box. Do these go through the plug attached to the inner wing just in front/down the side of the battery? I note this has 3 wires running through it? I have seperated these a couple of times and sprayed contact cleaner in. The lowest looked a wee bit corroded but nothing horrendous. Scratched the female part of the connector to try & improve. No noticeable improvement.Has anyone traced the wires from the brown coolant sensor back to the Bitron? I want to run a continuity check on it to see if thats where my problems lie. I am also not ruling out the Bitron going crazy. I checked the fan relays and there is no evidence of burned or corroded connections.
Any advice welcome as its embarrassing driving around with both fans running constantly flat out!!
Cheers
Alan
