Another Perentie "What is this" question.
« on: November 30, 2014, 11:43:05 AM »
Any ideas on what this "mod" might be?

Looks like someone has bypassed a relay. At a guess, the relay failed and they stuck that in there to bridge the wire coming from the switch directly to the wire going to the light or whatever that relay is supposed to handle. That would mean that the switch is now handling the full current draw of whatever it controls. I'd be looking up what relay goes there and replacing it before it cooks your wiring.

That's what I suspected.
I have a fuse diagram, but no diagram for what the relays are for. Can anyone enlighten me what the relays are from left to right? And, in particular, what the missing one is? ::)

Looks like a 100amp nonswitched fuse to me :o

Did a bit of a search but didn't find anything definite.
Check this thread on Aulro.

It doesn't say what it does, but identifies a couple of others and might give you a hand with narrowing it down.

Take the wire out and see what stops working. I have used that trick on my Defender TD5 when the fuel pump relay failed. Does not overload switches or wiring if you jumper the relay contacts - just simulating the relay being pulled on. Of course it may leave a component live when the ignition is off.

There are two possibilities in the schematic; one relay to dim the warning lights presumably when the blackout switch was on "reduced" or "blackout" (this relay is marked "not fitted" on the schematic and shown as jumpered like the one in your photo) and another to determine whether the "Cold Start" warning light comes on or not when the ignition switch is on START. This relay is also marked as not fitted on the schematic and is jumpered so that the light always illuminates when cranking (although I can't say I've noticed it myself). I'm guessing this is again part of the civvy loom that was intended for the V8? What does a cold start light signify?

So; pull the wire. If most of the warning lights stop working it's the warning light blackout relay and if the cold start light stops illuminating while cranking, it's the relay for that (which is also confusingly called the warning light black out relay on the schematic).

I can't be sure though, as my Perentie has the old style fuse box so a different layout.

If it's not one of those two I'd be very surprised, but there are two other possibilities.
