MB aux relays. Number 18
My aux relay panel had no relay in this position (top right as you look at it)
It has wires running to the back of it, but I can't find them on the wiring diagram. Does anyone know what the relay position is for? Thanks |

According to the parts lookup, it's for day running lights for Norway / Sweden

They're on-line at 7zap, but I've got an older version which is useful for the older cars as parts which show as obsolete on-line are listed on the old copy.

ahhh I get it now. The 7zap diagrams do show aux relay panel with position numbers.
thanks. My buzzer is definitely in position 2, but isnt buzzing. I will have to check the wiring at the back to make sure that it is supposed to be in there, and the same for position 18. Now that I have two possible candidates for the locations I can check on the wiring diagram to see what is actually there! As you know, 7zap shows alternatives for many relay positions, and the DRL and buzzer are two relays that have differing locations. |

The number two relay position is wired for the buzzer, and a buzzer is fitted in there but it's not working- so may need a new buzzer or have to check the wiring.
Relay 18 is, probably, the DRLs. There is a thick yellow wire (dipped headlights I believe)in that position, but the remaining wires don't match the wiring diagrams. I'll let that one slip... Last edited by BackintheFold; 21-04-19 at 10:00 PM. |
