||Mysteries of the 240 Headlight Step Relay
Unlocking the Mysteries of the Volvo 240 Headlight Step Relay.
And Test Procedure.
This relay is rather special in that it has a LATCHING function.
A latching function works like this: You can click and release a momentary button or switch (such as the 240 high/low beam lever) and the relay will then LATCH (or lock) in the ON or OFF position until the switch or lever is clicked again. For this 240 relay, one click latches it "ON" and another click latches it "OFF." The latch function is activated by a GROUND signal, which is created by the high/low beam lever.
I have created the diagram PDF (CLICK PHOTO OR LINK BELOW) for anyone who wants to better understand how this relays work.
I have also added a test procedure on page 2 if you think you might have a broken one.

to ELIMINATE your Volvo 240 Headlight Step Relay
This modification will accurately mimic what the original Volvo step relay does. It does not eliminate any need or recommendation you may have for additional headlight relays to feed high current headlights if you have them. Feel free to add those if needed. This type of setup simply copies the Volvo relay.
