Relay question

Wingnut · 2024-10-07 09:03:25

Under the bonnet, behind the battery,
There is a fuse and relay box.
I have the owners manual but it only lists the fuses and their functions not the relays.
I have a loose thin wire behind my alternator that seems like it should bolt onto the smaller terminal on my alternator.
With the ignition off and the wire connected nothing happens.
With the ignition on and the wire connected I can hear a relay clicking.
My question is does anyone know what this relay is for? (Green arrow)
There also appears to be a missing relay does anyone know what this one is for? (Red arrow)

I'm not sure about that modded wiring in the post linked but my loose wire definitely belongs there.
When I removed the smaller nut on the alternator the remainder of my broken wire that had been looped round it was still there.
On my van anyway it seems to be a switch discharge relay according to the electrical section of the manual I found on here.

Be sure to unzip it into its own folder or it'll be everywhere:D

my notes say its 1030 'engine running signal relay'
and your missing one is for front fog lamps

Great thanks for that!
It's in position R1 so I followed the manuals description, however your notes would make much more sense given that I've tested the terminal and it's only live when the motor is running.

I indirectly use that wire for my split charge relay, but I've tapped it off the blower motor fuse. Hm, maybe I should save the wiring and use that instead...

I think it would be a good location for your switch wire for that relay as in it wouldn't allow power through unless the motor is running but I think for a charge wire it'd be too small.

Yea exactly, it's just the signal wire. Looks like a good location for it, my relay is round there
