Hi - Have an EF Fairmont Ghia with recent Barra conversion. Used BA expansion tank so doesn't have low coolant sensor and now have constant low coolant light flashing on dash. Did a search and got a few different ideas but have not found a fix yet.
Short of removing the dash light has anyone resolved this - tried jumping the plug with a wire and using a 220ohm resistor but no joy. I'm crap when it comes to electrics so appreciate some who can explain the fix to me like im 5. cheers |

Yes some posts said 180 and some 220 but none confirmed it worked with either. Thanks for your response, ill give 180 a try, fingers crossed.

i could be completely wrong here but looks like the coolant sensor passes through upto 2 resistors in the wiring diagram
Pic 1 switch open current flows through both resistors Attachment: New Bitmap Image (4).bmp [ 491.13 KiB | Viewed 833 times ] Pic 2 switch closed Current bypasses one of the resistors Attachment: New Bitmap Image (4) - Copy.bmp [ 491.13 KiB | Viewed 832 times ] i couldn't tell you what resistor values are used or what order they are used in Hope this helps in some way

Thanks - I tried 220 and 180 on the plug and neither worked so your take on two could be right. I also put the multimeter on it and switched to 2k ohms got not change - I'm not sure if this means the plug is not even wired up or not? hoping a brain with electrical know how can chirp in and give me a much needed clue as Im stuck.
