Coolant alarm wiring

[haydn callow]

We have recently changed the supplier of the wire we use....One or two LCA's may have got out with the unamended wiring instructions.
If your alarm has Red and Red/black wires ..then the RED is switched live and the RED/BLACK is earth.
If your alarm has Red/Black and Black wires then the RED/BLACK is switched live and the BLACK is earth.

If you get it wrong the alarm won't be harmed...It just won't work.

Simples !! (the wire with the most RED in it is Positive)
