Blowing fuse, can't work out why.

[TPC]

Think back a few weeks... did the fuse start to blow before or after you had the lights apart?
It might be a good place to check again.

Probably as much as 90% of electrical faults are caused by us humans touching things that weren't broke

The idea of the globe is to limit current.
If you use a small wattage globe like an interior light, a test light like in the screwdriver style probe or an LED in place of the fuse it means that only milliamps flow in the circuit so nothing gets fried or melts.
Very handy trick when you get bad power shorts to earth, switch mode power supply faults etc
You can power the circuit up and actually chase voltages to find the short rather than just picking things out of your butt to disconnect and blowing a gazillion fuses

The problem started after doing some sand driving through dunes and on beaches, plenty of corrugation and some heavy bumps which would be just the thing to make some badly positioned wiring rub through.
Don't know why I didn't think to use a light in place of the fuse as it makes sense and I am a Technician myself.

the loom runs along the top of the chassis in the rear wheel arch maybe you cut the loom there
during one of those heavy "bumps", You should be able to see any damage.
Id also check where to OE loom splices into the towbar loom, that is a common area for faults

I have just about given up on finding this short and will have to take it to an auto elec to get sorted.
I have eliminated all the front and rear lights and disconnected most of the internal switches that have illumination.
Replaced the fuse with a 1w globe for the tests and it only has .035v on the output side and I can measure this same voltage at the lights and switches.

Bloody frustrating as I don't like being beaten.

I found the short Yaaaaaaa.

It was something I had done, I had taken out the ashtray in the front center console and replaced it with USB sockets and had screwed through the wiring for the ashtray light that I did not know was there, sort of thing I would kick an apprentice up the backside for.

Very happy its fixed now, time to put the car back together.

Gutsy admission mate. Glad you solved it.

Win...

Been there, done that, hid the evidence, noone knows any different.

Happy to provide the size 13 boots for the kicking at our next meet up. Glad you found it without having to pay someone.

consider yourself kicked lol
Good thing,,,,, you can rest easy now and not worry about,,,,, every minute of the day
Good tip on the light by ET,
