Mystery Perentie relays

[mark2]

There are several relays I'm struggling to identify/understand the purpose of on my GS 110.

The first set is under the fuse cover panel on the firewall.

The far left green Tyco relay activates when the key is turned to the 'on' position, however when removed, everything seems to work as normal. I thought it might have been for the glow plugs but the judging by the voltmeter, they still draw current when this relay is removed.

The second relay from the left kills the indicators when removed, so that one seems to have a purpose. Although this is not the flasher unit, the flasher unit is the black object next to the red (intermittent wiper) relay behind the fuse panel.

The engine will not crank when the third from the left is removed so I assume this one is for the starter solenoid.

The far right one appears to do nothing at all, I thought it may have been a headlight relay as I have heard rumours of Perenties having headlight relays, but the lights and everything else work ok when it is removed. There is no 'click' from this or any other relay when the lights are turned on.

Under the bonnet there are another two green Tyco relays behind the master cylinder.

When the one on the right is removed, the engine will start, but not stop, so this is related to the EDIC motor.

When the one on the left (with the fuse attached) is removed, the engine starts and stops as normal and all electrical accessories appear to work with or without it fitted, so its purpose is also unclear.

Any insights would be appreciated.

Re under the bonnet if you remove the fuse the engine will it start........we used to pull this fuse when we would leave the 110's and go shopping or a swim

No help here. Mine is still running glass tubed fuses!
Under the bonnet looks familiar minus the duct tape and cable ties

No, it wont start with this fuse removed, but will crank.

Sounds like you identified some of them - well done

I note that there is a headlight relay noted "if fitted" - it could be that one of your relays is for the headlights but not wired in.

I'm currently trying to identify the "mod" to one of my relays!

Perhaps they are for the top secret missile launch system. When you power up the relays do things explode around five kilometres away? Oops I've said too much

I think its the energiser circuit for the flux capacitor!

Hi
It maybe a mod to allow the headlights to remain on with the engine off.
Mine has this but I think the relay is in a different spot

Definitely one possibility; as you say, it's very hard to tell as the relay locations change from vehicle to vehicle. There are I think four relays in the loom that are bypassed from the factory as it's the civvy loom that has been stuffed around with to meet the military's needs.
