Stretch is having a fuse blowing

Has had an issue of bumper tail lights, stereo backlight, dash cluster light blowing. Only one fuse blowing. Tail light fuse 10A
Aftermarket light have been totally dismantled and not connected.
I thought it was that.

But blow again today.
Has blown several time.
Tail lights checked and tested.

Circuit tested at 3amps on the 10A fuse.

Thought we found and exposed wire but was a dead end again.
Any thoughts please

Only getting second hand info.

Blown several times during a period of time.
No new accessories fitted.

Found intercooler fan disconnected and re fitted. Not related I assume.

And before you ask, it's a 3lt.
And don't tell me that's the problem.

Why is multiple items on the one fuse when fuse box just says tail light.

checked the trailer plug and wiring if it has one?

Yeah id go straight to the Trailer plug too. 9 out of 10 times it will be there or in the line going to there. The tail light fuse is the Parker light fuse so its your parkers and dash. Bastard of a thing to fault find as it goes everywhere! The most obvious will be the Trailer plug then id go to the Front parker lights and Bull bar parkers next as they tend to be most exposed.

Also the loom hanging down behind both back wheels going to the parkers in the rear bumper take a hammering, especially if you don't have big enough mud flaps. much more likely to be the trailer plug or 1 of the 4 corners than behind the dash or other accessory if you have not aded anything.

From there id go to the accessories that are after market and see what has been spliced into the loom to pic up the dash light circuit and go there. Any lit switches or accessories that light up with the dash lights.

Has there been any recent work or anything fitted.?
So it just "happened" out of the blue.
As MR say the trailer plug is a good place to start
most time they will squash wires if not fitted correctly.

Trailer plug checked and cleared.
Didn't even think to go to the front Parker lights. Good thinking.

Checked all the tail light wiring back to the wheels.

Aftermarket tail light were fitted but removed from circuit.

LaSt thing fitted was the brake controller module but that was a couple years ago.

In the engine bay would only be the intercooler fan which I can check all the way back to source.

Thanx Daz, that's great

I'll have to go over the car again but clear everything that might be attached.

Ha ha. Brain fart time. If all else fails, try changing the bayonet style globes. I have come across some that have shorted out in the base.

Not sure if it's the same for GU's, but I had a weird issue a while back kinda similar to yours. I believe in the GQ, from what I could find/research etc, that there's a common earth that runs into the dash and controls a lot of these.

Mine was frayed in the engine bay and caused me some issues like these, I replaced the bad bit of wire and all good since.

Not sure if it helps, but food for thought.

I had an occasional fuse "pop" when I had the camper plugged in, seems that at times 10 amp was exceeded (flashers turned on?), auto elec said it was fine to put a 15 amp fuse in (having checked there were no other issues), never had a problem with the trailer attached since.

Note: I would only up the fuse if confident that the load on the circuit was a "legitimate" load and not another "issue". and that he wiring could take it (as advised by a qualified auto elec).

I had a issue with blowing the brake light fuse every so often , after working out what I had added traced it to the barn door table , screw and rubbed on the door brake light wire !

as suggested check some/all earth straps.
check under right rear thats where most ppl cut into loom for trailer plug

Yep, pretty much where my issue was a couple of years back, passenger side rear clusters..... wiring was a mess so to it to an auto sparky to sort out

originally mine was done with scotch loks but after venting
they soldered all connection then shrink sleeved them as you should
Lazy buggers eh

I had that exact problem and was the first thing I said to him.

At this stage everything mentioned is worth pursuing, even if it ends up all good.

The Patrol it self hasn't changed all that much in 20 yrs. lol

He has put in a 15 amp fuse just to get by but it pop that as well.
So went back to 10amps.

We have triple checked everything from the trailer plug.
I hope we checked it right and didn't miss anything.

Does it just blow randomly when the head lights are on? or something else is turned on? Is the fuse big enough?

Yes it blows randomly, during the day you really don't know it's blown.
At night obviously is noticed straight away.
As dash lights go.
Has happened once at night when indicating. But hasn't happened since when indicating.

We also tested the circuit with everything on and only tested 3 amps.

OK if it blows during the day then it is Not the Parker Light circuit and more likely a dead short mate. Insulation worn through would be my guess.

Yep my thoughts exactly...... hood place to look is at the main lot of wires that come through the drivers side bulkhead

I haven't confirmed if it has blown during times of not have headlights on.

But yes I suspect worn wiring somewhere.

Something rings a bell about the hazzard lights when towing will blow fuses
to way to solve it was to up the fuse rating buy 5 amps

I think the loom runs along the top of the chassis near the left rear wheel arch.
Good articulation will see the loom rubbed through, worth a look imo.
Or pinched by the body work

@MEGOMONSTER have you had any luck with this yet??
what year etc we talking about here???

Nothing for certain on the cause.

Well it's been a bit over a week now and no fuse is blowing.
So I wonder out of all the things we tinkered with, looked at and moved around has the problem disappeared or at least subsided.

Will keep you posted.

probably moved some bare wire away from some bodywork
