Low coolant alarm wiring
Posted: Sun May 25, 2014 11:42 am
Hi all,
Perry, our Bongo, came fitted with Haydn low coolant alarm, not convinced that it was working I did some searching on the old tinterwobble and found that when the bullet connector with the red and white wire was unplugged as the test function sure enough, nothing happened. Nothing happens when ignition turned on either.
I have found the tech sheet on this site that shows how to wire it up, all wired correctly and lives and earths present and correct.
The only part on that sheet that differs from mine is mine looks to have the two sensors in the header tank but only the top sensor is connected to the red/white wire, also connected to this top sensor is another red/white wire that goes to earth. I have disconnected this red/white wire from earth and the alarm now works. So my question is, where should this second red/white wire go, shoul it go on the lower screw sensor in the header tank and then to earth?
Cheers all
