Just a little update and some handy info.....
My new fans didn't seem to be running so ran a 12v live to test them - all good.
Relays? - tested for switching as above - all good.
Buzzed through with dvm whilst shorting the rad switch pins 1 to 3 and found only mv at the relay low volts pins. Worked back though the loom as far as poss without tearing the whole bloody car to bits but couldn't find a short/break so ran a fresh live with 5A fuse in-line and bingo! works a treat.
Whilst I had my sparky head on wired a manual override fan switch for both on slow speed.
Operating temps......
Now I have my oil temp gauge and outside temp sensor wired on a long lead under bonnet I will start to post a few results for oil temp vs engine temp vs under bonnet temp in different positions at various speeds. May be helpful, may not but should at least show the optimum position for air filter. So, for starters....
oil engine speed (mph) under bonnet under bonnet pos.
95 80 40mph 24 behind drivers headlamp
80 75 50mph 22 engine side of my heat shield
85 75 50mph 12! in cold air intake filter side of heat shield
80 75 40mph 34 bulk head behind battery
